Use manual tax from IDOC WPUUMS



Currently the business is posting aggregate sales order details using IDOC WPUUMS. One segment of this, E1WPU04, contains the tax information for the line item. As things stand now, SAP is calculating the tax internally and posting to a G/L Account, however we would like to use the value coming in from the IDOC segment E1WPU04 instead. The caveat here is that we can't just turn off automatic tax calculations since we need them for creating PO's, so we need to find another way to either: a). stop SAP from overwriting the tax data from E1WPU04, or b). Overwrite the calculated tax amount with the IDOC tax value.

I had originally thought to try option B but since we're using aggregated data I'm not sure that this would be feasible.

Does anyone have any suggestions on how I might go about accomplishing this?
