    there are different ways for it out of which one is LSMW (Legacy System Migragtion Workbench).

    For uploading we can follow 4 methods in LSMW

    1. Objective method

    4.IDOC

    With the use of any one of the above method, we can record in SAP System. For Recording Go to

    1. TCode : LSMW.

    2. Enter Project name, sub project name and object name.

    Execute.

    3. Maintain object attributes.

    Execute

    select Batch Input recording

    goto->Recording overview

    create

    recording name.

    enter transaction code (say FK01)

    start recording

    do recording as per ur choice.

    save + back.

    save + back

    5. MAINTAN FIELD MAPPING & CONVERSION RULE

    display change

    click on source field, select exact field from structue and enter

    repeat these steps for all fields.

    save+back

    6. MAINTAIN FIXED VALUES, TRANSACTION, USER DEFINED
