Hi,
In our system the DP document type tax determination is set to "SAP Tax Determination Logic with OT Tax Table", my understanding how this works is:
The system reads the tax code from the PO line and checks if the tax rate supplied by the external system matches uniquely. If the tax code exists in the PO line item and no match is found, the tax code is considered to not determine and the system stops checking further.
The issue we have is when we have always manually enter the tax code, even when the PO line tax code % matches the tax rate supplied by the scanned invoice. For example the PO shows a single tax code fo V0, the tax on the scanned invoice is 0 but the system is not automatically pulling in the tax code V0 and we have to always enter this manually.
thanks
