Question

how to change confirmed qty in schedulline?

Answer 1

SAP would normally have you accomodate this requirement by generating non-convertible planned orders that drive the ATP (use planning via planning materials or the like).But,if your offline ATP is sufficiently robust (with market penetration strategies,component allocations by segment,etc),this will probably not suffice.In this case,either use the ATP user exit,use product allocation instead of ATP,or store the original customer request date in a custom field and set the requested date = offline ATP date.
