derivation of commitment Item in the reservation (MB21) automatically

Dear Expertise

In spite of activating fund management and have the derivation rules based on valuation class or material number to read the commitment Item automatically, the commitment Item has been set as mandatory field for movement type 201 and the GL account related to the materials. when creating a reservation in MB21, the system doesn't derive the commitment item for the material which was selected and need to select manually. but we want it to be derived. how can I solve this problem?

I will appreciate any kind of guide.

Best regards

Anahita

    hi Anahita,

    please follow the snote below,

    128370 - FM a/c assignmt derivation for material reservations

    if you set:

      1. Set the field control of the FM account assignment fields in Customizing to 'optional entry' (Transaction OMBW).

    This allows you to create a reservation even without FM account assignment.

    and also look at the snote

    1321375 - Materials Reservation MM and Funds Management

    content is,

    Symptom

    Materials Reservation does not update Funds Management.

    Other Terms

    MB21, Material Reservations, MRP, Plant Maintainance orders, Integration.

    Reason and Prerequisites

    Clarify the Materials Reservation and Funds Management integration in different releases.

    Solution

    Until EA-PS 603, the material reservations were not integrated to FM.

    Before EA-PS 603:
    The material reservations(Created manually or generated from MRP or PM orders) did not update funds management.

    It is possible to set the Funds Reservation field as Optional field via OMBW for MM Movement Types because it is part of the general coding block fields, however, there was no integration between MM and FI-FM on that level.
    MM does not include any program logic for the 2 EMF fields ( KBLNR & KBLPOS ).
    So, before EA-PS 603, no integration existing between MM reservations and Earmarked funds processing.

    As of EA-PS 603:
    Refer to note 1278967. The integration of materials management to Funds Management is available via Business function PSM_FM_CI_1. When you activate this Business function an earmarked fund is generated when you create a material resrvation document. Funds Reservation field has to be Set as Optional field via OMBW for MM Movement Types as it is part of the general coding block fields. And Funds management should update at Goods Receipt or Goods receipt and invoice receipt(You can check in transaction OFUP).

    However, even when you have the business function turned on, the material reservations generated from Materials Requirement Planning(MRP) and Plant Maintainance orders are not integrated to FM. This happens, due to some technical limitations.
    These material reservations can be updated to Funds management and can be run through Availability control(AVC) by using program RFFMRP_MAT_RESERVATION.

    If you are in EA-PS 603, you may also check the related notes section in order to avoid known issues.

    Best Regards,
