Hello Jamie,
EWM delivery document works with Dates/Times from customizable table /SCDL/TDTTYPE, basic EWM system provides 25 basic Date/Time types.
Into the delivery document you may assign as many Date/Times as you need. Furthermore you can define them as Planned or Actual. They appear as sub-item table to the delivery header.
Delivery split is also supported in case Date/Times differ for delivery items.
Regards,
Petr
