I'm trying to grasp how the tax is being auto-determined in the Purchase Order.
Looking at the PO, it is making use of condition type TTX1 for the tax determination. From this, I quickly found out that the fields below are the ones being used by the condition type (well, more exists in the MEK2 app).
What I'm trying to figure out now is where the Tax Indicator: Plant and Tax Ind. Acct Assgt configuration steps are.
The configuration step Set Tax Indicator for Account Assignment doesn't assign the tax indicator to the AAC.
I'm just making sure that I'm not missing anything before I explain this to the users.
