I can't understand what is the problem here. Are you trying to create a parameter with dropdown option but have no idea how?

[aboooood]

the normal screen: 0100

subscreens: 0001, 0002, 0003, 0004.

so when is start the programm there is a dropdown box and if is select the first opstion it should call subscreen 0001 and the second option should call subscreen 0002 and so on...

but when i change the option it gives me a error that is the problem

[xiswanto]

is it run time error? please provide screenshot of it as it might give clearer information. Also, if possible, do provide the syntax for screen 0100 for both PBO and PAI.

Is the dropdown field name GS_BOTTLR_DATA_S-PREFORM? and is it being declared and used in screen 0100?

[aboooood]

the dropdwon box names GS_BOTTLR_DATA_S-PREFORM.

error is : dynpro 0006 is not found even tho i dont have that dynpro

this is my include i did some updates:

this is from normal screen :

[xiswanto]

the error does not make sense indeed. It is impossible to change into unknown screen without any code interferences.
Have you tried to debug the moment you change the dropdown value to check at which point the gv_screen value changed into 0006?

[Sandra_Rossi]

It's not recommended to have duplicate code: it's the same to initialize GV_SCREEN in PBO and PAI. Anyway, you should initialize GV_SCREEN only in PBO.

[aboooood]

xiswanto this is the problem, in user_command_0101 the gv_screen changes to the right screen but after the module ends the error comes. i cant track the gv_screen after this module.

[xiswanto]

aboooood did it changed into 0006 value or the correct screen value? also, try to rearrange the line position of the code below

PAI

MODULE user_command_0100.
MODULE user_command_0101.
CALL SUBSCREEN SUB

into these

PAI

CALL SUBSCREEN SUB
MODULE user_command_0100.
MODULE user_command_0101.

xiswanto i tried this before but didnt work. guess what, i just made a new report and mad a copy of the old report and now it works somehow 😕

[aboooood]

xiswanto sandra.rossi thx for all the comments ❤️

[Sandra_Rossi]

aboooood Thanks for feedback. By the way, I see that xiswanto typed manually the code, so please in the future paste ABAP code as text instead of image, so that it's easier for anyone to rearrange your code.

sandra.rossi oh my bad wont happen again

[Sandra_Rossi]

Oh, you even did it in the current question, thanks a lot!
