Summary :
SAP Note elucidates discrepancies between backward and forward scheduling impacting delivery group functions. Errors manifest when "CLASSIC" scheduling lacks working hours at the shipping point, when high rounding periods are configured in the shipping point, or when route and shipping point calendars are identical. The discrepancy arises due to different handling of the rounding-up period in both scheduling methods. Backward scheduling includes routing adjustments due to possible calendar changes, whereas forward scheduling might not round the goods issue date under similar calendar conditions. A solution includes general rounding of the goods issue date to standardize outcomes across scheduling types.
