Hi,
we are using IDOC WPUUMS01 for posting agg.sales from POSes. Problem is if on POS is given some amount of rebate to customer, SAP by posting always calculates the tax amount, which is in this case not correct. SO my question is can I with some user-exit, badi or something influence on tax calculation and overwrite it with one that came from POS. I have activated customer routine in pricing and with help of VOFM, and I'm writing the proper value into amount of tax, but somehow system again recalculates tax amount, according to SAP rules and this is not working. Any suggestion?
thx
