Microsoft Dynamics 365 and Power Platform Library

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 . public void ttsNotifyPreCommit()     {         if (!isInTtsNotifyPreCommit) ...

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.
