problem in screen painter

Former Member — Wed, 11 Feb 2009 09:52:51 GMT

hello!!!

i have two screens, in screen 1 i manually enter the project_no(input output field) and

press the DISPLAY button to call screen 2. in screen 2, i have drop down list boxes,

input output fields and radio buttons. all these elements are filled with information that are

retrieved from a transparent table zproject_details with project_no as its primary key...

this screen allows changes to be made in the info... thus if i change some value in this screen,

and press the SAVE button, then the change is updated in the table zproject_details...

the problem is, if i select another the value from dropdown list box the table gets updated,

if i select another radio button then also the table gets updated

but when i manually change the value from input output box, table does not change.

if the list boxes are originator and proj_type and if func_code of radio buttons is rad.

in pbo of screen 002.

data: up_originator(35) type c,

up_proj_type(15) type c,

up_radio(1) type c.

in pai of screen 002.

case ok_code.

when 'originator'.

move zproject_details-originator to up_originator.

when 'proj_type'.

move zproject_details-proj_type to up_proj_type.

when 'rad'.

if radio1 = 'x'.

up_radio = 'A'.

clear : radio2.

elseif radio2 = 'x'.

up_radio = 'B'.

clear: radio1.

endif.

when 'save'.

if not up_originator is initial.

update zproject_details set originator = up_originator.

clear up_originator.

endif.

if not up_proj_type is initial.

update zproject_details set proj_type = up_proj_type.

clear up_proj_type.

endif.

if not up_radio is initial.

update zproject_details set radio = up_radio.

clear up_radio.

endif.

endcase.

this is the logic i used, but i cannot do no_days(input output field) as

when 'no_days'.

...

plz help me out...

thx...

Hi,

Use below approch (syntax may not be correct as I have typed it in notepad but use it as guide line)

***In screen flow logic

PROCESS AFTER INPUT.
  module cancel at exit-command.
  chain.
    field: zproject_details-originator,
	   zproject_details-proj_type.
    module check_data on chain-request.	   
  endchain.
  
  module user_command_002.

***In abap code

module cancel input.
  leave program.
endmodule.

module check_data input.
  if zproject_details-originator is initial.
    message exxxx "throw error message here
  endif. 

  if zproject_details-proj_type is initial.
    message exxxx "throw error message here
  endif. 	
endmodule.

module user_command_002.
  save_ok = ok_code.  "good practice to save okcode
  clear ok_code.

  case save_ok.
    when 'save' " using constant for fcode here is better 
      perform save_data. "make it moduler instead of writing whole code in case statement
    
  enscase.
endmodule.

form save_data.
 ** do some additional checks if required before saving

 update zproject_details from zproject_details. " update database table here from work area contents
endform.

Regards,

Vishal
