This is because of header line issue if mara table:

CALL METHOD oref1->set_table_for_first_display
      EXPORTING
        is_layout                     = wa_layout
      CHANGING
        it_outtab                     = i_mara[]"--<<<This is Body of Internal table.
        it_fieldcatalog               = fieldcat

Hello

If you like to have weird errors due to faulty fieldcatalogs then you should create it manually otherwise I recommend to use fm LVC_FIELDCATALOG_MERGE.

If you are still using itab's with header lines then you have missed an important restriction that fortunately has come with ABAP-OO: header lines are banned from ABAP classes (and they should be banned from any programming object as well).

The EXPORTING parameter IS_LAYOUT describes the layout of your ALV list (e.g. which columns are displayed, column width optimization, subtotals, etc.).

Your data itab has to "feed" to CHANGING parameter IT_OUTTAB.

Regards

Uwe
