How to add new movement types when creating reservation?
When creating reservation(MB21), we should firstly input a movement type.
But in the entry list , there are only a few movement types available.
If we want to create reservation with other movement types, e.g. 313, 323,325,etc. how should we configure?
P.S. I've tried to add MB21 in Allowed Transactions in movement type settings. Then those new movement types will appear in the entry list, but I am still prompted error with message "Reservation for XXX is not possible. (Choose another movement type)" Message no. M7500
Please check SAP's online help on reservation with several movement types:
You can only create reservations for a particular purpose - you can only enter the one movement type and account assignment (such as a cost center) in a reservation.
Please check Ester Hernanz's professional answer - which mvt can be used for reservation:
In the standard it is only possible to create reservations for those movement types which have a value in the field 'Reserv.cat' (T156-RSTYP).
As you can see in the customizing transaction OMJJ, this field is located under the section for 'Internal control' (please do not change).
The F1-on-line-help for this field states:
"Account assignment of reservation:
Indicates the account assignment category of a reservation created with this movement type .
If the indicator has not been set, the movement type cannot be used to generate a reservation."
