purchase order and workflow

Hi user

We are using purchase order approval  and the problem is that when we create a purchase order and send to approval,

it create a line in monitor approval, if we add other line to the requisition, it create other line in the monitor approval

and finilly when we approve it, one line stay as terminated, is that ok or we are missing something.

The users said say what happen when they see 3 or 4 transaction thought the monitor approval and whi it said terminated with a date or some time

say terminated and never.

there is a file attached.
