How to fix ibr-sr-07 in UAE e-invoicing

What is ibr-sr-07?

ibr-sr-07 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 References & codes rule group. An e-invoice that fails ibr-sr-07 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

If there is a preceding invoice reference (ibg-03) , the preceding invoice number (ibt-025) MUST be present

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.
