Planned order without source
The standard behavior in APO is that when an order is created in APO, it creates with an internal number, then it goes to R/3 and gets the R/3 order number to APO and replaces the internal number by the R/3 number.
If I create a planned order in APO without an active PPM, then I have no source assigned in the planned order details.
Now, the question is does the system still goes to R/3 and gets the R/3 order number to replace the APO internal order? If not why?
