Ap has been running too long since last night it is still running. What should i first consider, what is the must not do. if anyone has had this issue in the past.

its holding up all of the production activity in AP.

The create accounting initiated the create accounting program .

now the creat accounting program is terminated

and the create accounting completed in warning.

 the create accounting was in Final Mode and NO for post to GL.
