I have imported opening balances for a custimer ie C0002 (Apex Ltd) and created some invoices for this customer.
Meanwhile a master data has already been created for the same customer (Apex Ltd) with a different code C0078. the
payment for this customer was then entered as payment on account for the C0078. But it should have been entered for
C0002. How do I resolve this to remove C0002 customer and work with the old one, that is C0078.
