101 movement & G/L A/C Contract & WIP

Dear SAP Friends,

In the system when we do the production confirmation thro T-code CO11N our accounting documents updated thro movement type 101

Also when we enter the subcontaracting material , Material inward (MIGO) with same movement type 101 also our standard purchase also enter in the system by 101 movement and same G/L account is updated.

All these Transaction are link with One G/L A/C name as Contract & WIP.

Now please tell how can I differentiate all these 3 Document?

Please reply.

Regards,

Chandra.
