Sometimes users may need a negative payment in a document. Such as when they receive a refund from vendors, or when the customer returns the item for a refund. With many systems this record needs to be entered manually and can be annoying sometimes. SAP Business One, however, offers an option to generate negative payments in the document, which settles the problem more efficiently. This function is available after SAP Business One version 9.1.
Go to Administration > System Initialization > Document Settings and click “Enable Negative Payment for Payment Wizard.” The system will notice that the negative payment method is only used when the document total is negative. Then users can have negative payment. The system will notice if the document total is negative as shown above.
