Fatal — invoice rejected Currency & exchange Shared Peppol rule PINT-AE 2026.5

How to fix ibr-077 in UAE e-invoicing

What is ibr-077?

ibr-077 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 the invoice document and belongs to the Currency & exchange rule group. An e-invoice that fails ibr-077 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

Tax accounting currency code (ibt-006) MUST be different from invoice currency code (ibt-005) when provided.

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.
