MASAV Supplier-Payment Files: File Structure and Errors That Reject a Whole Batch

In a MASAV supplier-payment file, each row is not simply a transfer. It belongs to a batch created from approved payments, beneficiary details, amounts, and execution date. MASAV publishes technical specifications, record structures, codes, and transmission instructions. Do not build a file from an old example or from a one-time export of another system.

A batch failure is more dangerous than a single supplier error. It can delay multiple payments, create pressure-driven manual handling, or cause a user to transmit again without knowing what was accepted. Add controls before file generation and retain the relationship between every payment and its batch number.

Four controls before generation

1. Confirm every approved payment appears once and has not changed since approval.
2. Validate beneficiary data under the business approved rules before file creation.
3. Reconcile the batch total to the payment list approved by finance.
4. Store the batch number, specification version, execution date, generator, and approver.

After transmission, update status only from the process response or return file, not merely because the file was created. When a batch is rejected, do not immediately create another one. First determine whether the issue is structural, isolated to a payment, or concerns an action already accepted.
