Forecast is loaded in months. When choosing weekly bucket to display in the planning book, for some products, forecast is correctly distributed equally in all 4 weeks. But for some products, whole monthly forecast is put into one (last) weekly bucket for that month. I do not know why this is happening. Since this is for some products, I assume it is due to some master data setting. What fields should I verify? Or in general also what configs or settings should I check and now, in order to solve this?
