Luan,
Our desire is to make it possible for the planner to clearly identify which sales order a certain receipt refers to, similarly as we see the link between a stock transfer order and the requirement that it generates in a source location.
This business functionality is normally met through the establishment of either a fixed or dynamic pegging structure.
Do you see a way to do this?
The solution would depend upon many factors, including the planning engine you are using. Since your existing solution is achieved through enhancement, creation of a corresponding pegging structure will probably require more enhancement. Create the functional spec and hand it off to your programmers.
Best Regards,
