We are in classic scenario.
For certain material group and purchasing group though we have maintained the "Always external procurement" and "Always purchase requisition" setting in the following config. but it still creates a Reservation for that material.
>Cross application basic settings
>Define Objects in Backend System (Purch. Reqs, Reservations
that specific material has a material master maintained for it in backend R/3. Does any of the config. in material master overrides the above mentioned SRM config. ?
Please reply back.
