Tanja:

As these transactions don't impact BankRec you can just do them in an AR Cash batch.

The other option is to use the Write Off function in AR to write off all accounts with a balance from $0.00 to $0.00 (be very careful that you ste the from and to amounts correctly as by default you could write off everything outstanding). The net effect of this will be to match up all of the outstanding transactions.
