Calling User Exit in SNP CTM
I have a requirement as detailed below.
The supply chain is multi-echelon. The product nature is MTO. The demand is captured in UOM 'Each'. The finished product has a bill of material of a returnable packing material and an actual sellable product measured in 'concentration'. This concentration reduces progressively day-by-day. The sales order carries the date of requirement at customer place and concentration required on a date of measurement. The supplier needs to back calculate the concentration, considering all his lead-times, and derive packing date, nearest dispatch date and concentration on packing day.
As the client has demand prioritization and production resource constraints, CTM is planned as RCCP solution. If user exit BAdI is created, how best we can call this BAdI and when can we call the same?
