Dual-Write | Unable to delete Postal Address Collections in D365 Sales

If you're unable to delete Postal Address Collection records in Dynamics 365 Customer Engagement Sales App, most likely the reason is there is related Postal Address records under that.

When I try to delete Postal Address records using Advanced find, I couldn't find the Delete button on it. If I open the record (for Postal Address), still couldn't see the delete button.

I used Bulk Record Deletion job to delete Postal Addresses and then I could go ahead and delete Postal Address Collections.

What are these tables you ask? These are added when you implement dual-write and install GAB solution in the dataverse. If the 2 environments are in sync, it is best to delete these records in F&O and let dual-write handle the deletion in D365 CE Sales.

We were in a situation where the F&O environment wasn't in sync with CE and we had to remove these records manually in CE only.

Hope it helps!
