Our CRM experienced an error and cannot update the record and experienced this error:
`

this happened when we try to update an existing record from in process to approved.

Answer 1

The error is pretty self-explanatory I think:
workflow 'Ph2 CSF Status' terminated with error 'Cannot update Closed or Cancelled Activity'
Your workflow has a step ("If RM approves the CSF") which is trying to update an activity which is already close/cancelled. You will need to update the activity before closing it or change the status to an active on before updating it (and then close it again).
