Hi, 

In IFS the Tax Code can be set on supplier level. Whenever using a different tax code in the supplier invoice it's not possible to proceed that invoice in the posting proposal whenever the tax code is blocked at supplier level.

The following error will appear in that case:

“You are not allowed to enter a tax code with tax type No Tax/Calculated Tax together with a tax amount. Please either change the No Tax/Calculated Tax tax code to a Taxable tax code or revise the tax amount to 0 for Item No 1”

However, whenever tax is allowed (for example 21%) on supplier level it's possible to proceed the supplier invoice without any error message.

Why doesn't this error occur in both scenarios, so also when a tax free code (0%) is used with a tax code on supplier level?
