I need to update the payment block field through SAP development rather than doing it manually in the MIRO transaction. I’m working on an automated process where invoices should have their payment status modified based on certain business conditions.
Has anyone found a way to programmatically change this payment block setting? I’ve been looking for suitable BAPIs, function modules, or direct coding approaches that would allow me to update this field automatically.
The payment block field I’m referring to is the one shown in the invoice document where you can set different block codes. Any suggestions on the best technical approach for this requirement would be really helpful.
I recommend using BAPI_INCOMINGINVOICE_CHANGE for updating the payment block in MIRO, as it provides a straightforward way to adjust the payment status programmatically. You will need to supply the invoice number along with the desired payment block code in the PAYMENTBLOCKING parameter. For more advanced control and error handling, MRM_INVOICE_CHANGE_SINGLE might be a better choice, allowing updates to multiple fields simultaneously. Just remember to commit your changes with BAPI_TRANSACTION_COMMIT to ensure they are saved. Although it’s possible to modify the RBKP table directly, using BAPIs is a safer practice in line with SAP guidelines.
You can also try the CHANGE_POINTERS method through ALE/EDI if you’re modifying invoices across multiple systems. I’ve had success calling BAPI_INCOMINGINVOICE_CHANGE inside a custom function module that validates business logic before changing payment blocks. Just populate the INVOICEHEADERCHANGEX structure - set the payment block indicator to ‘X’ and specify your new block code in INVOICEHEADERCHANGE. Handle exceptions properly since these changes fail if there are authorization issues or the invoice is stuck in workflow. Test in dev first - screwing up payment blocks can mess with cash flow big time.
