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.
