S_ALR_87100833 (program RFUMSV00) problem
Hello SAP experts,
recently we've started to use program RFUMSV00 to generate a XML for our tax authorities (based on note 1598181). However, we've noticed, that this program generates incorrect/strange data.
In line items, the tax base amount is different, than in the very same accounting document, displayed in FB03. In result, simple sum of line items does not match Total within the very same report. This is very strange and I don't understand why it happens. I've noticed, that the difference for each accounting document is same, for example 5% smaller amount for doc. A, 3% smaller amount for doc. B. This happens for both input/output tax.
Thanks for any suggestions, what could cause this problem.
