Fatal — invoice rejected Invoice lines & items UAE-specific rule PINT-AE 2026.5

How to fix ibr-189-ae in UAE e-invoicing

What is ibr-189-ae?

ibr-189-ae is a fatal validation rule in the UAE's Peppol PINT-AE e-invoicing specification — one of the UAE-specific rules. It is checked against the invoice document and belongs to the Invoice lines & items rule group. An e-invoice that fails ibr-189-ae is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

The scheme identifier (BTAE-17-1) MUST be SAC when Service accounting code (BTAE-17) is provided.

UAE impact: this is a fatal rule specific to the UAE PINT-AE 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.
