How to fix ibr-cl-20 in UAE e-invoicing

What is ibr-cl-20?

ibr-cl-20 is a fatal validation rule in the UAE's Peppol PINT-AE e-invoicing specification, inherited from the shared Peppol layer. It is checked against allowances and charges and belongs to the Allowances & charges rule group. An e-invoice that fails ibr-cl-20 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

Coded charge reasons (ibt-105), (ibt-145) MUST belong to the UNCL 7161 code list
UAE impact: this is a fatal rule from the shared Peppol layer, enforced in the UAE profile — an invoice failing it is rejected at the Accredited Service Provider gateway before it ever reaches the FTA. A rejected invoice means resubmission delays, and late transmission risks the AED 100-per-invoice penalty under Cabinet Decision No. 106 of 2025.

Where it applies

This rule is checked against allowances and charges of your UBL 2.1 invoice: 

cac:AllowanceCharge[cbc:ChargeIndicator = true()]/cbc:AllowanceChargeReasonCode
