The field tax prod posting group of table contains a value (NoTax) that cannot be found in relatable table(Tax Produt Posting Group)

I tried to use Purchase order (PO).

Coud you tell me why may cause this problem and how to fix it .

Hey Rodd,

If you will Navigate to the Item card and select that particular Item and then expand Invoicing Fast Tab, you will find there Tax Prod. Posting Group. Please look that column and then choose value. Reason is NoTax value is not available in that Tables hence you are getting this error.
