Is there anyone can guide me how to apply the open credit note to A/R invoice in SAP BUSINESS ONE? ( the credit note was not generated from that particular invoice)
appreciate your answer.
You could use automatic internal reconciliation, where the credit memo is not based open A/R invoice. It is on the banking module --> bank statements and reconciliations --> automatic reconciliations.
In reconciliation selection criteria --> choose BP and its code according to your credit memo and ar invoice bp cardcode.
In tab general/manual select internal and then click reconcile. The reconciliation windows will appear and your AR credit memo will be located in the open transaction in credit side and vice versa for A/R invoice.
