We are creating a Z report to calculate on-time shipments:
We need to know when the item was shipped out (we can get the GI date)
We need to know when the item was _supposed_ to be shipped out (schedule line date in sales order)
From the delivery item data, we can get the sales order number and line item number, but there doesn't seem to be any way to link to a schedule line (in case multiple ones exist) against which the delivery was made.
Am I missing something? This is a basic requirement and I can't find a clear answer - I must be missing something!
Thanks!
