error in workflow sumbission

When ever I am trying to sumbit workflow I have this error in ax 2012 cu 10: Stopped (error): X++ Exception: Cannot create a record in Alerts - event inbox data (EventInboxData). Inbox ID: 5638308102.
The record already exists.
I did not have permissions to delete all records from table

I found the solution from this link
