If you happen to face this error message "Copying pre-existing data completed with error, For additional details, go to initial sync details tab" while starting the dual-write entity map then please check you have setup the cross company data sharing policy for the underline table of the entity map (which is a data entity in D365 FO).
To resolve this issue, Go to System Administration | Setup | Configure cross=company data sharing screen and look for policy where you may have setup the underline table of the data entity used for dual-write entity map. Disable the policy and then run the dual-write job again, wait until it turns to running state. Enable the cross-company data sharing policy again choose No on the next open pop-up window otherwise it will run against all data across all legal entitles which might not be necessary for this exercise as you just disabled it to start dual-write entity map.
Being a developer I have to explore how a new feature or a framework has been developed and how can this be extended when needed. While working on dual-write implementation I came across many technical difficulties as the framework was not mature enough at that time since the dual-write is only generally available in end of March 2020 and I have been working on dual-write since mid-year 2019.
I must say MS has done tremendous amount of work to make the integration with Microsoft Dynamics 365 Finance Operations apps and Common Data Services via Dual-write
Bunch of AOT objects have been added at D365 FO side - screen shot taken from 10.0.13 these can grow with future releases if needed.
Application class has also been modified for dual-write, below method gets called when the database transaction tries to get committed, between ttsbegin and ttscommit.
publicvoid ttsNotifyPreCommit()
{
if (!isInTtsNotifyPreCommit)
{
try
{
isInTtsNotifyPreCommit = true;
if(sysTransactionScope)
{
sysTransactionScope.onTtsCommitting();
}
super();
if(this.canRaiseEvent())
{
this.onTtsNotifyPreCommit();
}
// Checks that all suspension of recId allocation invoked by calling appl.SysRecIdSequence().suspendRecIds() have been removed.
if(sysRecIdSequence)
{
if (!this.sysRecIdSequence().areAllRecIdSuspensionsRemoved())
{
throw error("@SYS344764");
}
sysRecidSequence = null;
}
if (this.ttsLevel() == 1)
{
DualWriteChangeProcessorBase::processTransactionPrecommit();
}
}
finally
{
isInTtsNotifyPreCommit = false;
}
}
}
Dual-write triggers only at ttsLevel 1, to understand this concept I did a small test.
From the trace log I can see that before ttscommit it goes to Application::ttsNotifyPreCommit and from there is makes a call to DualWriteChangeProcessorBase and in my scenario it goes to DualWriteSyncOutbound class.
If you dig deeper in this class, this creates the complete JSON message and sync this to CE.
In my next post, I will show what tables, entities, classes are involved and how you can see what JSON message is going out from FO to CE. Stay tune.
Let's continue where we left in first post "What got changed (Technical) in D365 Finance Operations with dual-write" our journey to understand what are the technical changes being done for dual-write framework.
This post we will look at what are highly used tables, entities, and classes involved for dual-write sync. I will only cover few tables, classes, and data entities but complete list of objects can be explored from AOT as shown below.
Business scenario: Create or update Vendor Groups in FO and sync over to CDS and vice versa.
Open Vendor groups screen - Accounts Payable > Vendors > Vendor groups
These fields are mapped between Finance and Operations apps and Common Data Service for Vendor groups dual-write template.
NOTE: only data will sync between apps only for mapped fields and the integration will also only trigger when we change data for these mapped fields in either side of the integration apps (FO or CDS) provided the sync direction is set to bi-directional (which is set for this scenario).
Requirement:You want to debug the integration (outbound or inbound)
Two important classes:
1. DualWriteSyncInbound
2. DualWriteSyncOutbound
If you want to debug data going out of FO to CDS (Outbound) then put a breakpoint at method WriteEntityRecordToCDS() of class DualWriteSyncOutbound.
This is quite extensive method and also gets a payload going out of FO to CDS, this payload can be watched and changed using all debugging features of D365 Finance and Operations.
Method BuildCDSPayload() being called inside method WriteEntityRecordToCDS() creates complete payload.
Pasting this just for reference purpose, this is subject to change at anytime so always refer to the updated code.
internalstr BuildCDSPayload(str cdsLookupUrls, common
entityRecord, str fieldMappingJson, ICDSSyncProvider
syncProvider)
{
var executionMarkerUniqueIdentifier
= newGuid();
DualWriteSyncLogger::LogExecutionMarker('DualWriteOutbound.BuildCDSPayload', true, strFmt('Execution start for record %1 with
uniqueId %2',
entityRecord.RecId, executionMarkerUniqueIdentifier));
CDSPayloadGenerator payloadGenerator =
syncProvider.CDSPayloadGenerator;
responseContract.DualWriteProcessingStage =
DualWriteProcessingStage::TransformingSourceData;
FieldMappingIterator fieldMappingIterator = FieldMappingIterator::ReadJson(fieldMappingJson);
if (fieldMappingIterator == null)
{
responseContract.AddRecordResponse(ExecutionStatus::Failed, strFmt("@DualWriteLabels:InvalidFieldMapping",fieldMappingJson), '');
DualWriteSyncLogger::LogSyncError('BuildCDSPayload', '', '',
strFmt('Failed to create CDS payload.
Error reason %1',
responseContract.GetFormattedResponseObject()), DualWriteDirection::Outbound);
}
while
(fieldMappingIterator.MoveNext())
{
FieldMapping fieldMapping =
fieldMappingIterator.Current();
var valueTranforms = fieldMapping.ValueTransforms;
var sourceValue = this.FetchSourceFieldDataFromMapping(entityRecord,fieldMapping);
// If there is a value default value transform then
the payload creation is skipped
// The payload gets added in CDSSyncProvider
boolean
skipPayloadCreation = false;
if (valueTranforms != null)
{
var
transformEnum =
valueTranforms.GetEnumerator();
while
(transformEnum.MoveNext())
{
IValueTransformDetails
transform = transformEnum.Current;
sourceValue = this.ApplyValueTransform(transform, sourceValue);
skipPayloadCreation =
(syncProvider.GetProviderType() != CDSSyncProviderType::CDSQueueSync &&
transform.TransformType
== ValueTransformType::Default);
if (transform.HasTransformationFailed)
{
responseContract.AddFailedFieldResponse(fieldMapping.SourceField,
strFmt("@DualWriteLabels:FailedTransform", sourceValue,
fieldMapping.SourceField, enum2Str(transform.TransformType)), '');
}
}
}
if (!strContains(fieldMapping.DestinationField,'.') || fieldMapping.IsSystemGenerated)
{
if
(!skipPayloadCreation)
{
payloadGenerator.AddAttributeValuePair(fieldMapping.DestinationField,
sourceValue,
fieldMapping.IsDestinationFieldQuoted,
this.FetchSourceFieldTypeCode(entityRecord,
fieldMapping));
}
}
syncProvider.AddSourceColumnTransformedValue(syncProvider.GetMappingKey(fieldMapping.SourceField
,fieldMapping.DestinationField) ,sourceValue);
}
responseContract.DualWriteProcessingStage =
DualWriteProcessingStage::ResolvingLookups;
var cdsPayLoad =
syncProvider.BuildCDSPayloadForLookups(cdsLookupUrls, fieldMappingJson);
DualWriteSyncLogger::LogExecutionMarker('DualWriteOutbound.BuildCDSPayload', false, strFmt('Execution ends for record %1 with
uniqueId %2',
entityRecord.RecId, executionMarkerUniqueIdentifier));
return cdsPayLoad;
}
To debug data coming in FO from CDS (Inbound) then put a breakpoint at method WriteDataToEntity() of class DualWriteSyncInbound.
Pasting this just for reference purpose, this is subject to change at anytime so always refer to the updated code.
private ResponseContract WriteDataToEntity(str entityName, str entityFieldValuesJson, str companyContext, booleanrunValidations = false, boolean isDelete = false, DualWriteTransactionId transactionId = '', str CDSSyncVersion = '', boolean isBatchCommit = true)
{
var executionMarkerUniqueIdentifier = newGuid();
this.InitializeInboundSync(entityName);
returnreponseContract;
}
After you are done with your entity field mappings for a required entity map e.g. for Vendor Groups, we started to look at in previous post to get the payload for dual-write integration, two records get created in the following tables.
1. DualWriteProjectConfiguration
2. DualWriteProjectFieldConfiguration
Records only get created when you Run the entity map and get deleted once you stopped it.
Run the entity map and check data in these tables,
1. Both tables link each other using Name field
2. For each entity map (e.g. Vendor groups) there are two records; one for Insert and Update and the other one is for delete which ends with _end
Import information about DualWriteProjectConfiguration table:
1. External URL field holds the CDS environment's URL which is linked with FO in this format https://<CDS environment URL>/api/data/v9.0/msdyn_vendorgroups. This API URL can be browsed to see available data in CDS environment
2. Project partition map field holds list of legal entities linked for dual-write, you can copy this list in notepad++ (or any where) and check all legal entities from there too - this may help you in troubleshooting
3. IsDebugMod field if marked then failure records are stored in DualWriteErrorLog table
4. Filter query expression field if you have defined Finance and Operations apps filter for entity maps it stores here
Import information about DualWriteProjectFieldConfiguration table:
Filter records from this table based on the project name you have retrieved from DualWriteProjectConfiguration table as shown below as an example
1. External lookup urls field holds information how different lookups from CDS tables are linked for this integration.
Trick and Tip: Copy data from this field and paste into Notepad ++, data looks like this
Format JSON and you can review all data easily in JSON viewer
2. Field mapping field holds information on how fields are mapped between both apps (Finance Operations app and Common Data Service)
Trick and Tip: Copy data from this field and paste into Notepad ++, Format JSON and it shows like this
DualWriteProjectConfigurationEntity data entity is the triggering point to sync data across based on pre-defined sync direction as discussed above.
In case you want to debug outbound call for vendor groups this will be the stack trace.
If you experience below error message when trying to import bacpac file into tier 1 (DEV) environment then use the suggested steps to get over this error and get your database imported.
Importing to database 'AxDB_Daxture' on server '.'.
SqlPackage.exe : *** Error importing database:Could not load package from 'C:\Users\Adminb1c06345af\Downloads\daxturebackup.bacpac'.

File contains corrupted data.
Based on this docs link https://docs.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/database/import-database, download the .NET CORE version of SqlPackage.exe.
This is the .zip file that can be extracted to C:\Temp\Sqlpackage-dotnetcore
From there, instead of using the Sqlpackage.exe under C:\Program Files (x86), use the Sqlpackage.exe in C:\Temp\Sqlpackage-dotnetcore.
Command will be:
C:\Temp\Sqlpackage-dotnetcore>SqlPackage.exe /a:import /sf:D:\Exportedbacpac\my.bacpac /tsn:localhost /tdn:<target database name> /p:CommandTimeout=1200
Dual-write does not work with the cross company data sharing policies in D365 FinOps (there are so many names but I am using this name for reference 😊).
Brief overview about cross company data sharing policy first to set the base for the readers, the Cross-Company data sharing lets you have your data accessible from multiple legal entities (companies in D365 FinOps). For example, if you setup a policy for vendors to be crossed-company then whenever you create a new vendor it will be created in all data sharing legal entities.
Now, What happened when you a table under cross-company data sharing (e.g. VendTable) and want to sync vendors through dual-write?
Since, VendTable is one of the data sources for Vendors data entity (dual-write entity map) and we know dual-write does not work well with cross-company data sharing by design. You get following error message when you try to Run the entity map.
"Copying pre-existing data completed with errors.
For additional details, go to initial sync details tab."
The error message is confusing and does not reflect the actual issue behind the scene - you will never be able to figured it out what is wrong until you raise it with MS dual-write team and share the activity Id of the job with them to investigate the telemetry (you don't have access to check this one 😒) then they share the root cause.
However, You can also investigate by putting a breakpoint in method validateDataSharingEnabledForEntityTableBeforDualWriteEnable() of class SysDataSharingValidation.
/// <summary>
/// Validates that cross company data sharing is not enabled when enabling Dual Write.
/// </summary>
/// <param name = "_entityName">The name of the entity containing the table being enabled</param>
/// <param name = "_tableName">Table in entity</param>
/// <param name = "_dataAreaId">Company info</param>
[SubscribesTo(classStr(BusinessEventsRegistrationBase), staticdelegatestr(BusinessEventsRegistrationBase, onTableEnabled))]
publicstaticvoidvalidateDataSharingEnabledForEntityTableBeforDualWriteEnable(str _entityName, str _tableName, DataAreaId _dataAreaId)
{
SysDataSharingOrganization sysDataSharingOrganizationTable;
SysDataSharingRuleEnabledsysDataSharingRuleEnabledTable;
selectfirstonly SharedTableName from sysDataSharingRuleEnabledTable
wheresysDataSharingRuleEnabledTable.SharedTableName == _tableName
join DataSharingPolicy, DataSharingCompany from sysDataSharingOrganizationTable
where sysDataSharingRuleEnabledTable.DataSharingPolicy == sysDataSharingOrganizationTable.DataSharingPolicy
&& sysDataSharingOrganizationTable.DataSharingCompany == _dataAreaId;
if (sysDataSharingRuleEnabledTable)
{
throwerror(strFmt("@DataSharing:CrossCompanySharingError", _entityName, sysDataSharingOrganizationTable.DataSharingPolicy));
}
}
Scenario:
The D365 finance & operations app is linked to Common Data Services through dual-write in development or sandbox environments. You are required to refresh databases in D365 FO and CDS both from another production environment (dual-write integrated (linked) environments in the scenario)
Steps to follow:
Scenario:
Project groups are shared across all legal entities in D365 finance & operations app so have setup under one of the cross-company data sharing policies. You are also required to setup dual-write table map for project groups to sync from FO to CDS. However, you get following error message when you try to Run the table map
"Copying pre-existing data completed with errors.For additional details, go to initial sync details tab."
Follow these steps to overcome this issue as a workaround.
Steps to follow:
Scenario:
There are times when you want to delete an entity from target entity list and when you do so, you face an error message which does not tell you where exactly the entity has been used.
"Entity cannot be deleted while dependent Entities for the processing group exist. Delete dependent Entities for a processing group and try again."
Solution:
Browse the environment by appending this part /?mi=SysTableBrowser&TableName=DMFDefinitionGroupEntity&cmp=USMF at the end.
For example; if the environment URL is https://daxture.sandbox.operations.dynamics.com then the complete URL will be https://daxture.sandbox.operations.dynamics.com/?mi=SysTableBrowser&TableName=DMFDefinitionGroupEntity&cmp=USMF
Filter for Entity and it will give you the DefinitionGroup where the entity has been added or used in data management import/export projects.
Get the DefinitionGroup name and search in the export/import projects under data management and either delete the whole project or remove the entity from the group. Try deleting/removing entity from target entity list and it should be good now.
This post focuses on the integration technologies available to have the Microsoft Dynamics 365 Finance Operations data available in Dataverse/Common Data Services/CDS. What could be better then having The biggest ERP system's data in Power Platform. You can Power Portals, Power Apps, Power BI analytical reports, use power virtual agents for inventory closing and year end closing processes, manage expenses and employee/contractors time entry processes, most of these processes can be even without logging to MS ERP (Dynamics 365 Finance Operation) so can safe on license cost too.
Let's see what options are available to integrate F&O data with Power Platform however, this post is dedicated to Virtual Entities.
3 Options available out-the-box to integrate F&O data with Power Platform;
👉 Data Integrator - Click on link to read more
👉 Dual-Write - Click on link to read more
👉 Virtual Entities - MS Tech Talk on Virtual entities
Before we jump to the installation and configuration part, let's see when were the virtual entities available and what features these have come up with compared to other two integrations technologies.
Virtual Entities Generally available
✔️ Finance and Supply Chain Management App: 10.0.12 or later
✔️ Dataverse: Service update 189 or later
✔️ Finance and Operations is available as a data source in Dataverse
✔️ No Finance and Operations data replication in Dataverse
✔️ Access all public data entities of Finance and Operations in Dataverse
✔️ Support all CRUD operations
Head to this link https://appsource.microsoft.com/en-us/product/dynamics-365/mscrm.finance_and_operations_virtual_entity and Get it Now
Enter your work or school account and Sign in
Choose the environment where you want to install this solution
Finance and Operations Virtual Entity solution shows as Enabled
Finance and Operations Virtual Entity solution is installed successfully - Hurray!! that was easy
The AAD application must be created on the same tenant as F&O.
Create a symmetric key for the application, Save and note it for later use.
Last week I explored very Interesting feature especially for developers where you right click on any field/control on the form and follow these steps.
One of the features of the dual-write is initial sync where you copy data from the source app (Finance Operation OR DataVerse) to the target app (Finance Operation OR DataVerse) depending on the selection in Master for initial sync option.
This initial sync is the Data Integrator service running behind the scene and copies your data over. You configure the application id for data integrator and add it both apps (Finance Operation OR DataVerse), I have documented it my previous post The Dual Write implementation - Part 2 - understand and action pre-requisites
Master for initial sync can be either Common Data Service (Dataverse) or Finance and Operations apps. For example, If I choose Finance and Operations app in below example where I am syncing Functional Locations then all records will be copied from Finance and operations to Dataverse.
Initial Sync is a full push means if an individual row fails to sync, you cannot resync only failed ones. If the initial synchronization only partially succeeds, a second synchronization runs for all the rows, not just the rows that failed to be synced during the initial synchronization.
For example;
1st initial sync Run for 1000 records from FO to CDS à 700 passed and 300 failed
2nd initial sync Run will again run for 1000 records
Do check Considerations for initial Sync from Microsoft Docs
Initial Sync runs against all legal entities configured for dual-write. If you have entered a filter for a specific legal entity in a table map at Finance and Operations app side, as shown below as an example, this will not work for initial sync as it will run against all legal entities configured for dual write under environment details.
Scenario:
Database synchronization failed with following error message.
It happened after I refreshed the tier 1 (DEV) environment of MS D365 FinOps from a sandbox environment database. The original database was named to AxDB_Orig as part of this refresh process.
Scenario:
You are willing to work on Microsoft Dynamics 365 Finance Operations product and want to get your hand dirty with some development. You are hearing so much about this product but never got a chance to work on this MS ERP.
Andre wrote a detailed post on how you can setup a trial environment for MS D365 Finance Operations
Solution:
With this post I will explain a step-by-step guide on how;
NOTE: You would need Azure Subscription to deploy VM
First create new domain to perform all above steps - its easy just follow following steps
1. Open this site Office 365 E3 in cognitive mode or as guest and go with Free Trial option
2. Fill in details - you can use your personal email or sign up for a new email account and use that one
3. Provide as much as information you can - it will be good for you :)
4. Choose verification method, I always select text me
5. Provide Once verified enter your business details and check the availability
6. Sign up and you are ready to use this account to perform all above steps mentioned under solution section
Manage your subscription option will take you to Microsoft 365 admin center where you will have 25 free user license for the whole month. You can use this account to sign up for teams and enjoy all features for the whole month FREE!!
Log on to LCSlcs.dynamics.com using above created account
Create new project by clicking on + sign and fill information - product name should Finance and Operations
Your LCS project is ready, click on hamburger sign and go to Project setting
Under Organization and ownership the type should be either customer or partner which will be one of them based on the account you have used to log on to LCS. If your account is linked to a partner organization then this will be partner and it will be customer if your account is of type customer.
Remember, the created account in post is not linked to either Partner or Customer so we cannot deploy any tier 1 environment in LCS as in order to connect to Azure portal with LCS the company account should be either customer or partner.
So, we are blocked here :(
Here is the trick to convert this prospect account to customer account to unblock ourselves.
Browse https://trials.dynamics.com/ and choose Finance and Operations, enter your new account and hit Get Started. This will deploy a new trial environment with demo data in next 30 minutes. Read Andre's post to find the downside of this environment.
After trial environment deployed, refresh project settings page (you can sign out and sign in again in) to see the changes where it has changed type from prospect to customer
Now you are the customer so let's continue our journey of completing our solution but this is it for this post and we will continue deploying cloud hosted environment through LCS in azure portal in next post.

Complete all steps and verify your account either via email or SMS.
Get Started
Choose region on next screen and Submit
Log on to Lifecycle Services https://lcs.dynamics.com with an account you created above (e.g. I created this account 1DynamicsDaxture@1dynamics675.onmicrosoft.com). First time you will following screen
Click on + sign to create new project (Select product of your choice - I have chosen Finance and Operations)
Project is created, click on Project onboarding and follow the documentation to complete project onboarding. This is a must step before environments will get deployed. Comment to discuss more about this process with me.
Upon project onboarding completion, the configure button will be enabled (note for this example, I have not completed the onboarding process hence the configure button is disabled)
As the LCS website gets slower and slower and the database backups get bigger and bigger. Use AZCopy to download objects out of LCS asset library. it is an incredibly quickly vs manually downloading the files (>1min for a gig vs 1 hour+)
Download AZCopy to the environment (https://docs.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-v10?toc=/azure/storage/files/toc.json#download-azcopy) and user the PowerShell command: .\azcopy copy "LCS SAS Link""LocalPath"
D The only issue I noticed is that the local path had to be into a folder, not the root of the drive (so "C:\Temp" not "C:\" which is more related to windows security then anything else.
Below is the example:
Extract AzCopy zip folder to C:\Temp folder
