Update on FM use cctr assigned to PA30 even input alternative acct.assgn

Hi Expert,

I create TRIP-TRAVEL REQUEST and enter alternative account assignment is different cost centre (cost centre B) than cost centre assigned to PA30 infotype 017 (cost centre A). When approval PRAP, availability control apply on cost centre A -payment budget exceeded A/commitment item ZXY, and update the business trip commitment to funds centre A even the alternative cost centre inputed is B.

It is happen also when distributing % to other cost centre, or use alternative co object like wbs element. Updating on FM using cost centre assigned to PA30.

Do you have suggestion about this issue?

    Hi Dewi,

    I was quite busy and left forums for a while but I am back and I will try to help you.

    It seems that your issue is related to the note 658163 which says:

    "This is not a program error. The FM account assignment derivation runs again, however, the already

    existing FM account assignment is treated like a manually entered account assignment. The reason is that the system can not distinguish whether the FM account assignment existing in the source code is derived or manually entered.


    Depending on your requirements the following options are possible:

    o Delete the FM account assignment before you change the account

    assignment element. Then the FM account assignment is derived

    from the changed account assignment element again.

    o Set the assignment of the FM account assignment to be definite

    for the corresponding account assignment element in the

    Customizing of the FM account assignment derivation.

    o Check the derived account assignment in enhancement SAPLFMCH001,

    component EXIT_SAPLFMCH_001.

    o Include a customizable warning message (for example FICUSTOM001)

    to warn the users about incorrect entries. In Releases IS-PS

    4.62, EA-PS 1.10 or higher the message can be issued in user

    exit EXIT_SAPLFMCH_001."


    Please consider the options listed as FMDERIVE will not overwrite the already filled value since it does not know if it was manually entered or not.

    I hope it helps you 😊

    Best Regards,
