Module Pool - Table Control - Data not getting displayed in Control

Question

Hi,
I have a table contol in my module pool program. In my processing I am filling an internal table & then in my PBO I am linking the internal table to table control. The issue is that even though the internal table is getting filled correctly (found through debugging), the data is not getting populated in table control. Nothing is populated on screen. I am writing part of code below
Declaration:
Types: begin of ty_control,
        SELECTED TYPE C,
        TEXT TYPE DPR_CAUSE_T-TEXT,
      end of ty_control.
CONTROLS :  TBL_CONT TYPE TABLEVIEW USING SCREEN '9001'.
DATA:       lt_table_cont type TABLE OF ty_control with header line.
Fields in TBL_CONT:
   TBL_CONT-SELECTED
  TBL_CONT-TEXT
PBO Flow Logic:
  MODULE STATUS_9001.
MODULE fill_data.
  LOOP AT lt_table_cont WITH CONTROL TBL_CONT cursor TBL_CONT-top_line.
  ENDLOOP.
PAI Flow Logic:
Loop at lt_table_cont.
   MODULE UPDATE_DATA.
endloop.
MODULE USER_COMMAND_9001.
PLZ let me know what might be the problem. I have been trying to figure out but cant.
Thanks.

Hi Sonali,
           When ever you need to do anything with the table control, i mean if u want to display data in table control or you want to validate the data entered in table control Should be done within Loop and Endloop.(PBO or PAI's which ever is appropriate)
Here the data is not bieng displayed in ur table control because you have not used the MODULE fill_data  between
LOOP AT lt_table_cont WITH CONTROL TBL_CONT cursor TBL_CONT-top_line.
ENDLOOP.
so do it like this
LOOP AT lt_table_cont WITH CONTROL TBL_CONT cursor TBL_CONT-top_line.
MODULE fill_data 
ENDLOOP.
this will solve your problem.
