So here is where I'm at with this issue.
We use a program called SQL-RD to send out automatic emails from SQL Table information.
It's sort of complicated so I'll do my best to explain. We use Dynamics GP when an EC is completed an email is sent out to a list of people. How this happens is when the EC is completed in GP it creates a row in a sql table. Every 5 minutes SQL-RD checks to table to see if there is anything new in it. If there is then it triggers a workflow which sends out the email. This is where I'm seeing an error. A few weeks back something happened and now we getting an error during the workflow.
Here is an example of the error:
Failure: ECN - Trigger Email - Task Execution: DB Modify[Insert Ready for Signoff] - [Microsoft][SQL Server Native Client 10.0][SQL Server]Violation of PRIMARY KEY constraint...
