    Hi Javier,

    try with below links

    hope this also helps you.

    Create project, Subproject, Object (freely definable, for the purpose of

    identification) – Use create icon in the menu. For example

    Project FI Finance

    Subproject GL GL MASTER

    Object GL GL Master

    2. Continue F8, Now you will see series of steps. Select the step and execute

    it (Ctrl-F8). In each steps, we will do some activity and save it. Then

    system prompts for the next activity.

    3. Maintain object attributes. By default the screen in display mode, Click

    on ‘pencil button’ to get into change mode. (This is applicable to upto the

    activity assign files). In this screen select ‘Batch input recording’ and

    in ‘Recording’ give name (freely definable) sal ‘GL01’ and click on Overview.

    In this screen button (Recordings overview). Now click on create button for

    recording. Give name and description, Now it will ask for the transaction

    code, enter the transaction code and enter the data, the way you want fill in

    the SAP screens/fields with legacy data. Then save the transaction. Now save

    again to save the recording. After that you select the button ‘default all’,

    then save it. And come back, now the cursor is on next activity.

    4. Maintain source structures. Here create the structure by specifying name

    (freely definable).

    5. Maintain source fields. In this screen, click on ‘copy fields’ (Ctrl+F8),

    here select ‘From data file(field names in 1st line)’. Now the system asks

    for the file, select your text file, the system will copy the fiedls from

    text file (tab delimited file. It contains field names in the first row).

    Save it.

    6. Maintain structure relations. Generally, we need not do anything here.

    7. Maintain field mapping and conversation rules. Here put the cursor on the

    field and click on source field, now you can see the list of field available,

    from which select one which is equal to the field on which you out the

    cursor. You can also write coding (ABAP Code) on any field for the purpose of

    validation of data. Save it.

    8. Maintain fixed values, translations, user-defined routines. Here also you

    can maintain values, if required.

    9. Specify files. In this screen, place the cursor on Legacy data, then click

    on create button. The system asks for the file name, (the text file, in which

    the legacy data is there), enter the file name, description and select Data

    for one source structure (table), delimiter as ‘Tabulator’, file structure

    as “Field names at the beginning of the file”.

    10. Assign files. The file name you specified in earlier step comes

    automatically here, If the file name does not come, then click

    on ‘assignment’ button and assign the file.

    11. Read data. Here specify the ‘transaction number’ (the number not less

    than the number of rows in the text file). Execute it.

    12. Display read data. Here, you can see the values, how the system read the


    13. Convert data. Here specify the ‘transaction number’ (the number not less

    than the number of rows in the text file). Execute it.

    14. Display converted data. Here, you can see the values, how the system

    converted the data, after interpreting conversion rules specified in the

    earlier steps. This is the data that is actually goes into SAP, once the

    Batch Input session is run.

    15. Create batch input session. Specify the ‘batch input session’ name for

    identification and also select the ‘keep session’.

    16. Run Batch Input Session. Select the batch input and click ‘Process’, from

    there select ‘foreground’ or ‘background’. Now the program runs and update

    the data in to SAP. You can analyze the batch input for the successful

    postings, errors.
