IBR-127-AE error
Due date is required when money is owed
If the amount due is more than zero, the invoice needs a payment due date (IBT-009), unless it's a credit note.
UAE invoices often state terms ('net 30') without a date. The spec wants the date.
Fails
<cbc:IssueDate>2026-10-01</cbc:IssueDate>
<!-- no cbc:DueDate -->Fix
Add cbc:DueDate. Issue date plus your payment terms is usually right.
Passes
<cbc:DueDate>2026-10-31</cbc:DueDate>Schematron
