Exchange rate

An invoice in any currency other than the dirham must also report its VAT in AED, at a stated rate. You choose where that rate comes from, once, per entity — and an invoice already in AED is unaffected by all of it, because nothing needs converting.

One switch decides it

On the entity's own page there is a single setting, Use Central Bank exchange rate. Everything on this page follows from it.

SettingWhat happens
On (the default)The UAE Central Bank rate published for each invoice's own date, applied automatically. Nothing to configure, nothing to keep up to date, and the rate on the invoice in your accounting system is not used.
OffThe rate comes from your PINT Mapping instead: either an invoice field you nominate, or the staging area. Use this when your books must file at your own contracted or booked rate.

It is on unless you turn it off, including for every entity created before the setting existed. Nothing changes underneath you.

With it on

The rate is the one the Central Bank published for the invoice's own date — not today's, and not the date it happened to be sent — walking back to the last published business day when the invoice falls on a weekend or a holiday.

The exchange rate row on PINT Mapping is locked while this is on, and it is locked on purpose: the platform reads the Central Bank and nothing else, so a source configured there would be ignored. A screen that lets you choose something the document will not use is worse than one that does not offer the choice.

An invoice is refused only when the Central Bank published no rate at all for that currency on or before its date — a currency they do not list, or a date far enough ahead that nothing has been published yet.

With it off

Turn it off and the choice moves to PINT Mapping, on the Currency exchange rate row. There are two ways to answer it.

What you chooseWhat happens to each invoice
Point it at an invoice fieldPick any field your accounting system sends — an exchange rate, a currency rate, a custom field. Every later invoice is converted at whatever that field holds, with nothing to type.
Will be provided at invoice levelNo field is read. Each foreign-currency invoice waits in Staged Invoices until you enter the rate yourself. An AED invoice never waits, because it needs no conversion.

A missing or unreadable rate is never guessed.If the field you nominated is empty on a particular invoice, holds text, or holds zero, that invoice is held in Staged Invoices exactly as if you had chosen to provide it by hand — it is not quietly filed at the Central Bank rate instead, because an entity that turned this off did so to file at its own.

Which one you want

Leave it on unless you have a reason not to. It is the rate the authority expects, it needs no setup, and it cannot drift.

Turn it offwhen your ledger has already booked the invoice at a particular rate — a contracted rate, a group rate, or one your accounting system fixed at the time — and the AED figures you file have to match your own books rather than the published rate for the day.

The setting is per entity, so entities that need different answers can have them. Changing it affects invoices processed from then on; documents already filed are untouched.
