Hi Raf,
Thanks.
Actually the business scenario if of MTO, whereas material (RM) is procured with SO assigned. Subcon PO is also created with SO assigned. Thus the requirement of 541 E comes here. That is why this requirement is there. I tried to make the "SC Vend" check editable through ABAP, but
default setting getting restored.
Please see if any option / alternative you have.
thanks
