Identify from where Table update is being done

Hi Mentors,

We have a situation where GL is hit when Parts are Issued in Work Order transaction. As a standard process, the SBL is updated with Work Order No for either debit/ credit transaction. But in our case both the debit and credit lines are updated with SBL Value. When we captured the debug logs when we see the Insert or update statements for F0911, only 1 line is updated with Work Order No in F0911.SBL.

Question:,

We suspect that there could be table trigger which would be doing that for us but how do we know and find that table trigger. how do we find which table trigger might be doing this. Is there any log which can help us find that?
