Hello,
I have a purchase order where I can complete the warehouse receipt, but when invocing the PO using the post function I get the following error:
Every sales line must have same Tax Calculation Type = SalesTax.
I can see no issues with any of the tax posting groups or set ups, and no differences between the items on this PO and other items, or other PO's. Further, the error references the purchase header which contains no fields for tax groups or calculations anyway. I'm at a loss to understand what is preventing the posting of invoice for this purchase order.
