When a user posts in Apps, an error message pops up stating: "Violation of PRIMARY KEY constraint."
This issue is related to a bug with SQL Server. You'll need to manually reset the identity column for the table with the issue.
1. Open SQL Server Management Studio (SSMS).
2. Use the following query to check the current identity value of the fact table stated in the message.
3. Set the identity value to a number that is greater than the current value.
DBCC CHECKIDENT('TableName', RESEED, NewValue)
