Hi,

Change here for 'YTC2' : select-options s_matnr for mara-matnr.

As matnr is alsready declared when 'YTC1'.

since it is the same program, you will have to rename your variables...you can still have the same type so that you are not affected.

case sy-tcode.

when 'YTC1'.

selection-screen begin of screen 0100.

selection-screen begin of block b1 with frame title text-001.

select-options matnr for mara-matnr.

select-options lifnr for lfa1-lifnr no intervals.

selection-screen end of block b1.

selection-screen begin of block b2 with frame title text-002.

parameters r1 radiobutton group g.

parameters r2 radiobutton group g.

parameters r3 radiobutton group g.

selection-screen end of block b2.

selection-screen end of screen 0100.

when 'YTC2'.

selection-screen begin of screen 0200.

selection-screen begin of block b3 with frame title text-003.

select-options s_matnr for mara-matnr.

selection-screen end of block b3.

selection-screen begin of block b4 with frametitle text-004.

Hi,

Write all the parameters and selection-screen.

use selection-screen output event

ie select-options : matnr for mara-matnr modif id 'MRN'.

at selection-screen output.

if sy-tcode = 'YTC1'.

loop at screen.

if screen-group1 = 'MRN'.

screen-active = '0'.

modify screen.

endif.

endloop.

endif.

regards,

The program will not allow to declare same variable twice. so you need to change the matnr with a cnange (i.e. s_matnr) in 'YTC2'.

when 'YTC2'.

selection-screen begin of screen 0200.

selection-screen begin of block b3 with frame title text-003.

select-options s_matnr for mara-matnr.

selection-screen end of block b3.

selection-screen begin of block b4 with frametitle text-004.

parameters r4 radiobutton group g1.

selection-screen end of block b4.

selection-screen end of screen 0200

Selection-screen, parameters and select-options define the screen for the abap interpreter. They are NOT executed ABAP commands, and as such will ignore any control structures.

e.g.

IF 1 EQ 1.
  PARAMETERS p_1 TYPE c.
ELSE.
  PARAMETERS p_2 TYPE c.
ENDIF.

Will produce a selection screen with two parameters - p_1 and p_2.

So, your "WHEN" structure is useless. You have to define both screens. You can't make it conditional.
