I could not locate any useful exit or enhance-point too. As per my understanding, what is required at the basic level is that I'll pass the details to my custom FM (same import parameters as SD_BACKORDER_UPDATE) for the scheduling agreement and then I need to check for the material availability date and confirmed quantity to update the same in JIT Delivery Schedule or Forecast Delivery Schedule as per my requirement.
Are there any other standard FM's which can help me achieve this requirement?
