Hi Andreas,
When I change it to overwrite, do I have to remove the reversal indicator or leave that as it is. We are using 3.5 version. Could you explain what do you meant by if there is a reversal? Does additive brings the number with negative sign if there is a change to the existing record? Like, first record was 20, second 19 so -1, third record changed it to 15 so became -4 so total -5? If it was overwrite, it would have come back with 15. I checked ROOSOURCE table, in the source system, this data source is ABR image. This is a customized ODS with lot of key figures with addition instead of overwrite. Does the reversal indicator routine could cause any conflict if changing to overwrite to the update rule for order qty?
