What is MR BR in SAP?

MRBR in SAP stands for "Manage Blocked Invoices." It is a transaction used to manage and release blocked invoices in the system. When invoices are blocked due to discrepancies such as price variances or missing purchase orders, MRBR allows users to review the reasons for the block and take appropriate actions to resolve the issues, enabling the invoices to be processed for payment. This function is essential for maintaining efficient Accounts Payable operations.
