Hi vinod,

ABAP gives you a structure called SCREEN. It contains all the screen variables.Find out the field names and put it in the loop and make its visibility property as 0.

loop at screen.

if screen-name = ''.

screen-visible = 0.

endif.

modify screen.

endloop.

Hi Ravi,

            as you said i had given SCREEN-VISIBLE but it is showing me error as screen doesn't contain component called visible,but there is a component called INVISIBLE.

Hi Vinod

Please provide the complete details. Where is this radio button..? Are you calling TMG via call transaction or some FM?

Hi vinod

     when you are creating tmg , you will specific a function group name  and sap generate a func group which contains that tmg . you can view in se80 , specifying function group name. In that , screen contains single screen 100 or two screen 100,200 .

     screen you can create module in pbo .u can find all field name in that screen.

    loop at screen.

   if screen-name = ''.

   screen-visible = 0.

   endif.

   modify screen.

   endloop.

Hello,

It is very difficult and unacceptable to make modification to generated code of TMG.

Also there will be a risk involved if the TMG is regenerated then custom code may be over written.

Better you develop a simple ALV grid report to maintain the table rather than going for changes into TMG.

      After Writing this code i got only the empty values for that particular field but i dont want the whole column.

Can any one help me in this.

Hi vinod,

Use screen-visible = 0. not screen-invisible.

Screen-invisible means data will not be visible. To hide column we have to use screen-visible = 0.

hi ravi ,

          i accept your point but the thing is showing error as invisible doesn't exists.

Hi,

we can control how to access a field of TMG with the maintenance attribute.

Maintenance Attribute of a View Field - BC - ABAP Dictionary - SAP Library

Thanks

Did you try to modify the table-control itself tctrl_<view name> in PBO.

Its subfield CXTAB_COLUMN is an internal table of column, you can modify field INVISIBLE to disable display of a column. Do it before the LOOP AT EXTRACT WITH CONTROL tctrl_<view name>.

HI Vinod,

There might be few things which could be a problem,

1. Just check whetehre the field name is correct.

2. You can use only active property not invisble.

3. Just check in debug mode whether the code is executing perfectly.

Just make sure these things. Because i think except these there is no other mistake in code.
