Journal Entry Approval and editing

Jenny O'Neill

I do not understand why a journal entry can be edited after it has been approved! What prevents someone going into the entry and changing it in between being approved and being posted, when the approver and the poster are two different people? That seems to limit the usefulness of the approval. Also, if someone does edit a journal entry after it has been approved, why does the status not automatically revert to Pending Approval? How would someone know if a journal entry had been altered in between the approval and the posting without this requirement?
