Hi, experts.

I effort to config outgo halfway goods contented process successful SAP EWM.

1.MB21 : Create reservation(movement benignant 201)
2.MIGO : Post goods contented notation to the preservation number.
         →outbound transportation is created.
3./SCWM/PRDO : Create warehouse bid & warehouse task notation to the outbound transportation number.
4./SCWM/MON : Check the outbound transportation point & warehouse task.

I would similar to cheque outgo halfway codification successful those documents, but, I tin cheque it successful the outbound transportation only.

In the outbound delivery, I tin cheque it successful the "Account duty object".

That point besides exists successful the warehouse task, but the point is blank space.
