PINT AE validation rule for UAE e-invoices

What it means

Each payment instruction may state the mandate reference only once.

How to fix it

Give a single mandate reference in each payment instruction.

The official wording of this rule is in the PINT AE specification published by OpenPeppol.

بالعربية
