SAP Note 23547 - Movement type for goods movements w. ref. to reservations

Symptom:

In the process of transactions MB1A (goods issue), MB1B (transfer posting), MB1C (other goods receipt), and MB11 (goods movement), the user enters a movement type (e.g. 201) and presses the "Reservations..." pushbutton (or chooses Goods movement --> Create with reference --> To reservation... from the CUA menu). In the dialog box which then appears, a reservation is entered or selected that has been created with a different movement type (e.g. 261).
The system carries out the goods movement on the basis of the movement type used for creation of the reservation (in the above example: 261). The system ignores the specified movement type (in the example: 201).
The system proceeds in the same way for movements that are entered with reference to an order or material document.

Cause and prerequisites

This process has been designed this way, because it should not be possible to change the original purpose of a reservation (in the example, it was created for a production order) by specifying a different movement type (in the example, for a cost center).

Solution
1. When entering a goods movement for a reservation, specification of a movement type is not required.
2. If you wish to reverse a goods movement for a reservation, you can do so by selecting Goods movement --> Reverse with reference --> To reservation... from the CUA menu. In this case, the goods movement is carried out with the relevant reversal movement type (in the example: 262).
