AX - Error message: "Cannot delete a record in Raw registrations (JmgTermReg). An update conflict occurred due to another user process deleting the record or changing one or more fields in the record."

This error shows in "Job registration" module for worker.

The reason is probably in "optimistic concurrency model" on the table JmgTermReg (table part is locked for changes)".

My solution:

1) Set JmgTermReg.OCCEnabled to No. Save it.
2) Connect with worker to "Job registration", and run action for him again (for example - clock out).
3) Set JmgTermReg.OCCEnabled again back to Yes. Save it.

Note: The reason could be bad session time on some client.
