When creating a PO with schedule lines and outputting it via ORDERS or ORDCHG, we noticed that the schedule line numbers aren't included in the IDoc, and the schedule lines are simply sorted in chronological order. This isn't a problem if the original schedule lines were chronological, but sometimes they're not.
So when the PO comes back from the external system, SUS in our case, there doesn't appear to be an easy way to correlate the dates going into EKES with the dates in EKET.
Has anyone addressed this issue in the past? Or have any ideas on how to address it?
