Hi,

Can you be more clear on this .....

Is it a custom screen or a standard screen.

In any screen you can find the field names in the menu painter. Have a look in to that......

Venkatesh

Hi,

When you define a paramter or select-option on the selection screen, the % is prefixed to the field name. These elements of the screen are used to name the field labels on the screen.

You should ignore these and only use the the name of the screen elements that you have defined in the selection screen when you are processing the screen in the loop at screen code block.


parameters p_matnr like mara-matnr.

"Now here %p_matnr will be the screen-name for the text label of the field p_matnr ( selection text that is displayed in the screen

loop at screen.
 case screen-name.
  when 'P_MATNR'.
    " do the processing for the field matnr
 endcase.

Looking at your code , I can see that you want to probably hide some fields or block.

What you can do is assign a modif id to each of the screen element that you want to hide. This modif id is then stored in the group1 attribute of the screen table at runtime.

So you can do something like this :


selection-screen begin of block b1
parameters p_matnr like mara-matnr modif id mat.
parametsr p_werks like mara-werks modif id mat.
selection-screen end of block b1.

at selection-screen output.


loop at screen.
  case screen-group1.
    when 'MAT'
       screen-active = 0.
 endcase.
endloop.

The above code loops at the screen and makes both the parameters invisible and since there is nothing left on the screen, the block will also be made invisible.

Hope this helps.

regards,

Advait
