Each of these has one cause far more often than any other. Work down the list.

1. The report menus are missing entirely. You are not in the UAE Tax Reports privilege, which gates both menu items. Under Settings → Users, set the role to User (reports, drill-down, export, record filings) or Manager (all of that, plus the Configuration → UAE Tax Reports group). Then reload the browser — the menu is built at page load.

2. The report opens and every figure is zero. Three candidates, in order of likelihood: - The period contains no posted journal items. Widen the dates. - The entries are still in draft. Turn on Include draft. - Your invoices use taxes that do not carry the UAE tax tags. Check them against VAT Box Mapping — this is the Lesson 4 problem, and it is the one that produces a report that looks fine and is quietly incomplete.

3. Every standard-rated supply lands in one Emirate box. Your customer contacts have no Emirate, so everything is taking the Default Emirate fallback. Fix the contacts first, then the default, then check Emirate Mapping. Lesson 7.

4. Draft invoices are not counted. By design — the reports read posted entries only. Toggle Include draft for a one-off view, or set Include Draft by Default in UAE Tax Settings if that is how you always want to work.

5. The TRN will not save. It is validated as exactly 15 digits. Enter the FTA TRN with no spaces, no dashes and no prefix.
