What it means

BR-KSA-EN16931-04 is one of the validation rules for the e-invoice. A warning: the invoice is accepted with a note; fix the cause in the next invoices. The severity comes from ZATCA's own SDK.

Fields the rule names

The rule text names 8 fields. BT is a single invoice element, BG is a group of elements and KSA is a Saudi-specific element.

• BT-93
• BT-100
• BT-137
• BT-142
• BT-94
• BT-101
• BT-138
• BT-143

How to fix it

The steps follow the wording of the rule only; we add nothing ZATCA did not say.

1. Open the invoice XML and find the fields the rule names: BT-93, BT-100, BT-137, BT-142, BT-94, BT-101, BT-138, BT-143.
2. Correct the value or element in the XML, or in the POS setting that writes it, then generate the invoice again.
3. Check the corrected file with ZATCA's SDK 238-R3.3.8 before you send it.
4. This is a warning and the platform accepts the invoice with it. Fix the cause so it does not repeat in the next invoices.
