Duplicate Controlling Document (FI)

HI All,

When we park our document using fv60 system also create a controlling doucment for it. tables for controlling document are COBK, COEP. Now when we post our document normally through fv60 it works fine. But when we create batch input session for document using FBV0

and then process the session it creates another controlling document for it.

Can some one explain the process or give solution

Thanks
