I need to update the payment block status through programming instead of doing it manually. I have been working on an automation project where I need to set or clear payment blocks for vendor invoices during MIRO processing. Does anyone know if there are any function modules, BAPIs, or custom code approaches that can handle this? I tried looking through the standard SAP documentation but couldn’t find a clear solution. I’m specifically looking for ways to: - Set payment block codes automatically - Clear existing payment blocks when certain conditions are met - Update the block status based on business rules Any code examples or guidance would be really helpful. Thanks in advance!
I’ve dealt with similar automation requirements in our SAP environment. The most reliable approach I found was using BAPI_INCOMINGINVOICE_CHANGE after the MIRO transaction has been posted. This BAPI allows you to modify the payment block field in the invoice document header. You’ll need to pass the invoice document number and specify the payment block code in the INVOICEHEADER structure. For clearing blocks, just pass an empty value to the PAYMENTBLOCK field. I also implemented validation logic using user exits in the MIRO transaction itself, specifically in enhancement MRM_WORKFLOW01, which lets you set blocks during the posting process based on your business rules. Make sure to handle the BAPI return messages properly and commit the changes using BAPI_TRANSACTION_COMMIT. The key is ensuring your automation runs after the invoice document is fully created but before the payment run processes it.
