Hi,

Plz find belwo simple code, which will create Fields(dynamic) for each plant , and under the plants releavnt materials will display.

let me know if any issues.


data: itab1 type table of mara with header line,
      itab2 type table of marc with header line,
      itab3 like itab2 occurs 0 with header line.


data: cl_cont type ref to cl_gui_custom_container,
      cl_grd type ref to cl_gui_alv_grid,
      scr type scrfname value 'SCR'.



DATA: t_cat TYPE LVC_T_FCAT,
       w_cat type lvc_s_fcat.
select matnr ersda from mara into corresponding fields of  table itab1 up to  30 rows.

select matnr werks from marc into  corresponding fields of  table itab2 for all entries in itab1 where matnr = itab1-matnr.

itab3[] = itab2[].

sort itab3 by werks.
delete adjacent duplicates from itab3 comparing werks.
data : n type i value 1.




loop at itab3.
w_cat-col_pos = n.
w_cat-fieldname = itab3-werks.
w_cat-coltext = itab3-werks.
append w_cat to t_cat.
clear w_cat.
n = n + 1.

Hi,

Please Test the following Code it will Create a Dynamic internal table like any DB table, you must enter the Correct DB table name in the Input Parameter.

PARAMETERS: tabname TYPE string. " DB Table Name

  DATA: itab_ref TYPE REF TO data.

   CREATE DATA itab_ref TYPE STANDARD TABLE OF (tabname).
   FIELD-SYMBOLS: <itab> TYPE STANDARD TABLE.
   ASSIGN itab_ref->* TO <itab>.

BREAK-POINT.

Kind Regards,

Faisal
