R12 AP validation adjusting tax even if automatic tax not used
1. An AP invoice is created with one item and one tax row - both manually created.
Automatic Tax Calculation is not used (Allow Tax Applicability under Configurarion Owner Tax Option is disabled)
2. Item row is discarded.
Tax row is automaticly discarded.
3. A new item row is created.
The LOV for Type (Item, freight for example) does not contain Tax - for that reason new tax row is not possible to create and the old tax row is locked not possible to update.
Any ideas what the issue might be?
