I’m working on a project where I need to update the payment block status automatically instead of doing it manually through the MIRO transaction. I’ve been trying to find a way to programmatically modify this field but I’m not sure what’s the best approach. Has anyone worked with this before? I’m looking for options like: - Any standard BAPI that can handle this - Function modules that might be available - Custom ABAP code solutions - Table updates if that’s safe to do The goal is to set or remove payment blocks on vendor invoices based on certain business rules. Any guidance on the proper SAP-recommended way to achieve this would be really helpful.
For payment block changes, try FI-CA function modules if you’re working with contract accounts, or standard posting FMs like FB_CHANGE_DOCUMENT. I’ve had better luck with ACCOUNTING_DOCUMENT_CHANGE than BAPIs in some cases. You could also use the BTE framework to automatically update payment blocks based on your business rules. The main tables are BSIK/BSAK for vendor line items, but don’t update them directly - it’s too risky. Test everything thoroughly in dev since screwing up payment processing can cause serious financial problems.
Had the same issue last year. I used BAPI_INCOMINGINVOICE_CHANGE to modify payment blocks on vendor invoices. This BAPI lets you update invoice fields including payment block status without touching database tables directly. You need to populate the INVOICEHEADERX structure with change indicators and pass the new payment block value in INVOICEHEADER. Don’t forget BAPI_TRANSACTION_COMMIT after to save changes. Way more reliable than direct table updates, which mess up data integrity. The BAPI handles validations and workflow triggers that manual updates miss. Check out CHANGE_DOCUMENT function modules too if you need audit tracking.
