Creating a credit memo for a specific prepayment invoice in Dynamics 365 Business Central

Creating a credit memo for a specific prepayment invoice in Dynamics 365 Business Central can indeed be tricky when multiple prepayment invoices exist for a single sales or purchase order. According to Microsoft's standard functionality, generating a credit memo will typically reverse all posted prepayment invoices associated with the order.

This default behavior ensures that all prepayment amounts are reconciled correctly, but it might not align with your unique business needs where individual prepayment invoices require separate handling.

For those who need more tailored solutions, customization is the way forward. Engaging with a Business Central partner or looking into the AL development environment might provide the flexibility you need.

For a deeper dive into the standard processes and potential for customization, referring to Microsoft's official documentation can be a valuable resource. Remember, aligning your system to your business processes is key for operational efficiency.
