Data not displayed in tablecontrol in abap modulepool after change_col_attr

[former_member38147]

I am fetching and displaying data in table control. If I don't change the column attribute then it is displayed fine with the data. All columns are input enabled by default.

However, if I try to change it; no data is displayed. In debug, data is present in the table.

The below code is written in the change_col_attr module inside a loop at table control columns for the screen in the PBO. I am calling the below in a form since I need multiple logic. And those forms are in the loop. What am I missing?

IF p_screen-screen-name IN lr_invisible. "range containing fields
    p_screen-screen-active = 0.
    p_screen-screen-invisible = 1.
    p_screen-invisible = 1.
  ELSEIF p_screen-screen-name IN lr_inactive.
    p_screen-screen-active = 0.
    p_screen-screen-invisible = 0.
  ELSE.
    p_screen-screen-active = 1.
    p_screen-screen-invisible = 0.
  ENDIF.

Hi arunk89

In your PBO of screen you might be code like below:

PROCESS BEFORE OUTPUT.

 MODULE inits_0100 OUTPUT.

*&SPWIZARD: PBO FLOW LOGIC FOR TABLECONTROL 'TC_DATA'
  MODULE TC_DATA_CHANGE_TC_ATTR.
*&SPWIZARD: MODULE TC_DATA_CHANGE_COL_ATTR.
  LOOP AT   IT_DATA
       INTO WA_DATA
       WITH CONTROL TC_DATA
       CURSOR TC_DATA-CURRENT_LINE.
    MODULE TC_DATA_GET_LINES.
*&SPWIZARD:   MODULE TC_DATA_CHANGE_FIELD_ATTR
  ENDLOOP.

In the module inits_0100 output. you write a perform statement called PERFORM hide_display.In the hide_displayyou write your hide code. However, I am not sure about what you are trying to do.If you want to make readonly, then put only input = 0.Regards,Venkat
