COPA Reconciliation with GL Account - Value Fields many to many relationship

Hello Gurus,

I wante to see if there is way to reconcile numbers in GL Account/Value Fields mapping in many to many relationship.

Here is the scenario:

When I run a gross profit report developed based on value fields calculations as well as postings from CE11000  and try to reconcile against income statements, there are differences. In a perfect world, I would have had one value field mapping to one GL account but with this setup, I am trying to come up with some sort of process where I can isolate postings and nail down where the differences are originating from. Any suggestion on how I can go about doing this?

Thanks in advance for your response.

Regards,

Sagar
