Would anyone have an answer or be able to comment as to why when stock materials are planned in a Plant Maintenance Work Order and Res./Purc. req. is selected as NEVER a Reservation is still generated. Should it not behave with the expectation that it would never create a Reservation????

Any feedback would be greatly appreciated.

When the Never option is used, the system will always create a reservation in table RESB, but the Movement Allowed (RESB-XWAOK) is not active so it cannot be used.

This is standard SAP, and I don't know why they did it this way. It maybe for performance, or database consistency reasons..
