Reservation creation for Network order in MB21

[Former Member]

I have requirement in which Reservation for Network orders need to be created in MB21 transaction code (Manual reservation creation). Currently reservation are created in CN21 or CN22 transaction automatically. When I am trying to create Manual reservation through MB21 I am getting error message "Manual reservation for order category 20 is not allowed". Whether it is possible to create manual reservation for network order by any other way or by config change?

Hi,

Unfotunately, the process of manually creating reservations is not allowed for order categories 10 - 50.

The message M7 126 cannot be customised. It is a fixed program message that cannot be altered by the user. It is therefore not possible to bypass as you have tried. This restricted was added via note 305231.

best regards, Takashi
