Troubleshooting Synchronisation Errors


Effective November 2020:

  • Common Data Service has been renamed to Microsoft Dataverse. Learn more
  • Some terminology in Microsoft Dataverse has been updated. For example, entity is now table and field is now column. Learn more

There are lots of moving parts involved in integrating Business Central with Dataverse, and sometimes things go wrong. This topic points out some of the typical errors that occur and gives some pointers for how to fix them.

Errors often occur either because of something that a user has done to coupled records, or something is wrong with how the integration is set up. For errors related to coupled records, users can resolve those themselves. These errors are caused by actions such as deleting data in one, but not both, business apps and then synchronising. For more information, see View the Status of a Synchronisation.


This video shows an example of how to troubleshoot errors that happened while synchronising with Dataverse. The process will be the same for all integrations.

Errors that are related to how the integration is set up typically require an administrator's attention. You can view these errors on the Integration Synchronisation Errors page. Examples of some typical issues include:

  • The permissions and roles assigned to users are not correct.
  • The administrator account was specified as the integration user.
  • The integration user's password is set to require a change when the user signs in.
  • The exchange rates for currencies are not specified in one or the other app.

You must manually resolve the errors, but there are a few ways in which the page helps you. For example:

  • The Source and Destination fields may contain links to the row where the error was found. Click the link to investigate the error.
  • The Delete Entries Older than 7 Days and the Delete All Entries actions will clean up the list. Typically, you use these actions after you have resolved the cause of an error that affects many records. Use caution, however. These actions might delete errors that are still relevant.

Sometimes the timestamps on records can cause conflicts. The "CDS Integration Record" table keeps the timestamps "Last Synch. Modified On" and "Last Synch. CDS Modified On" for the last integration done in both directions for a row. These timestamps are compared to timestamps on Business Central and Sales records. In Business Central, the timestamp is in the Integration Record table.

You can filter on records that are to be synchronised by comparing row timestamps in the table "Integration Table Mapping" fields "Synch. Modified On Filter" and "Synch. Int. Tbl. Mod. On Fltr.".

The conflict error message "Cannot update the Customer record because it has a later modified date than the Account record" or "Cannot update the Account record because it has a later modified date than the Customer record" can happen if a row has a timestamp that is bigger than IntegrationTableMapping."Synch. Modified On Filter" but it is not more recent than the timestamp on Sales Integration Record. It means that the source row was synchronised manually, and not by the job queue entry.

The conflict happens because the destination row was also changed - the row timestamp is more recent than Sales Integration Record's timestamp. The destination check happens only for bidirectional tables.

These records are now moved to the "Skipped Synch. Records" page, which you open from the Microsoft Dynamics Connection Setup page in Business Central. There you can specify the changes to keep, and then synchronise the records again.

Remove Couplings Between Records

When something goes wrong in your integration and you need to uncouple records to stop synchronising them, you can do so for one or more records at a time. You can uncouple one or more records from list pages or the Coupled Data Synchronisation Errors page by choosing one or more lines and choosing Delete Coupling. You can also remove all couplings for one or more table mappings on the Integration Table Mappings page.

If an entity with a unidirectional coupling is deleted in Business Central, you must manually delete the broken coupling. To do that, on the Coupled Data Synchronisation Errors page, choose the Find for Deleted action, and then delete the couplings.
