Hello Chandra,
Yup, i have coded under the ZPnnnn00, and yes, Screen 200 is also available.
here is the code that i have developed so far.(this is only for the pop up screen part)
Mod. Pool        ZP049400                       Active
INCLUDE zp049410.
INCLUDE mppdat00.
INCLUDE fp50ppsb.
INCLUDE mppers00.
INCLUDE zp049420.
INCLUDE zp049430.
INCLUDE zp049440.
*&      Module  USER_COMMAND  INPUT
      text
MODULE user_command INPUT.
  IF sy-ucomm = 'RNE'.
    CALL SCREEN '201' STARTING AT 1 1
                         ENDING AT 50 5.
*&      Module  USER_COMMAND_0201  INPUT
      text
module USER_COMMAND_0201 input.
if ZROUTE_BTN = 'X'.
  ZNEWEVAL = gt_p0490-ZZCURREVAL.
endif.
endmodule.                 " USER_COMMAND_0201  INPUT
i was advised to create a similar functionality that FM: 'TRM_POPUP_TEXT_INPUT' is producing.
the pop up screen is similar to my requirement where i have to input a text.
i wanted to avoid that suggestion because recreating an FM is none of my capability yet.
if there really is a way to do it, that is not time consuming... i would go for it.
initially, what i have in mind is:
Since:
screen 200 is a subscreen of screen 2000,
that makes 201 NOT part or NON existing in MPnnnn00.
right? or i have it wrongly?
thanks again.
