PINT AE validation rule for UAE e-invoices

What it means

Every attached file must state its file type (mime code).

How to fix it

Add the file type to each attachment.

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

In Alya Books

Alya Books builds the invoice XML so this holds; the official rule files confirm it on our sample documents.

بالعربية

يجب أن يذكر كل ملف مرفق نوع الملف (رمز mime).

أضف نوع الملف إلى كل مرفق.
