How Add TRN In Purchases & Sales Order

Dear Sir,

we ( UAE ) added Supplier TAX Number in purchases order but when we want to printing its not showing on printed page. how to setup in printing TAX Number.

Hi,

Supplier’s tax ID is fetched into Purchase Invoice only, and not in the Purchase Order. You can insert a Custom FIeld to have it fetched into Purchase Order as well.
