Assign internal table name passed through routines

[Former Member]

Dear experts,

How can i pass the name of P_TAB in from fieldcat_init ?.

i call the method of an object(ob) of class .

If i call debugger on p_tab in form fieldcat_init ,i can see the data.

But how to assign it

wa_fieldcat-tabname = P_TAB.

I tried this but gives me dump.

CALL METHOD OB->printalv( exporting alv_data = t_excel ).

method printalv.
perform printing tables alv_data.
endmethod.

form printing tables p_tab like t_excel.

#  PERFORM fieldcat_init tables p_tab USING gt_fieldcat .
  PERFORM eventtab_build USING gt_events[].
  PERFORM comment_build  USING gt_list_top_of_page[].
  PERFORM disp_rep tables p_tab.

endform.


FORM fieldcat_init tables p_tab USING  p_gt_fieldcat .

  CLEAR wa_fieldcat.
  wa_fieldcat-fieldname    = 'MATNR'.
  wa_fieldcat-tabname      =  P_TAB.
  wa_fieldcat-seltext_m    = text-001  .
  wa_fieldcat-outputlen = 18.
  wa_fieldcat-emphasize    = 'C410'.
  APPEND wa_fieldcat TO it_fieldcat.
ENDFORM.

Line with # needs clarification.

Hi Aditya,

You described your "p_tab" in TABLES section

describe your form like that :

FORM fieldcat_init USING p_tab p_gt_fieldcat .

ENDFORM.

and give the name of your table to this subroutine

not the table itself :

PERFORM fieldcat_init USING 'ITAB' p_gt_fieldcat.

wrong : PERFORM fieldcat_init USING ITAB p_gt_fieldcat.

I hope it helps.

Hi,

Look at the way you append fieldcat:

  APPEND wa_fieldcat TO it_fieldcat.

please try to append right subroutine parameter

I did by decalring thing as follows

alv_tab like (type of p_tab)

append lines of p_tab to alv_tab.

then talking only for ALV_TAB.
