ABAP Looping in internal tables

Question

Hi,
I am working on alv report which fetches matnr with no transaction data by passing in ekpo,mseg,ekko tables and query is working is fine and append matnr in it_final to display.
But now I want to display matnr & matkx-makt but to get this field I have to compare with it_final-matnr to get the corresponding material description. correct values are fetched but issue is with display.
Code attached in file below.
Any help to sort out this would be appreciated.

You could simplify you report
- Join MARA and MAKT
- Check non existence of records in subquery
Sample :
TYPES: BEGIN OF record,
          matnr TYPE mara-matnr,
          maktx TYPE makt-maktx,
        END OF record.
DATA: itab TYPE TABLE OF record,
       lo_table TYPE REF TO cl_salv_table.
PARAMETERS: p_mtart TYPE mara-mtart.
START-OF-SELECTION.
   SELECT * INTO CORRESPONDING FIELDS OF TABLE itab
     FROM mara
     JOIN makt
       ON mara~matnr EQ makt~matnr
     WHERE mara~mtart EQ p_mtart
       AND makt~spras EQ sy-langu
       AND NOT EXISTS ( SELECT * FROM ekpo WHERE matnr EQ mara~matnr )
       AND NOT EXISTS ( SELECT * FROM ekbe WHERE matnr EQ mara~matnr )
       AND NOT EXISTS ( SELECT * FROM mseg WHERE matnr EQ mara~matnr ).
END-OF-SELECTION.
   cl_salv_table=>factory(
     IMPORTING
       r_salv_table   = lo_table
     CHANGING
       t_table        = itab ).
   lo_table->display( ).
Now execute some performance comparison with your FOR ALL ENTRIES options, and decide yourself.
(How did you choice the tables to check EKPO & EKBE but no EBAN, no RESB ?)
