I am facing a problem when analyzing KE24 and KE30 reports for a specific period, customer and article. Some characteristics have assumed negative values, since the bases of sales for them were all positive in the period. I am trying to search for the source of the CO-PA postings for the Top-Down and I couldn't find any negative value. Have you ever faced a problem like this? Would you help me to analyze this kind of problem?
Any help is welcome and points will be awarded.
