AFAIK PAI is triggered after you press the ENTER key. may be in the code you are clearing the values in the PAI.

Hi,

The keyboard event 'Enter' does not have a default sy-ucomm or a Function code associated with it.

So, whenever you press Enter, it triggers the PAI (sy-ucomm would be blank) and somewhere in your code the value is being refreshed. You can debug thoroughly to find where the problem is.

You can assign a Function code for Enter. Go to the GUI Status of the Screen -> Function Keys -> You will find a icon Enter (the one with the tick mark in a green circular background) -> Assign Function code like 'ENTER'.

Now in your PAI, restrict your code saying

if sy-ucomm = 'ENTER'.
 "Logic
endif.

Great Dude. You have done it.

FYI...

DATA ok_code LIKE sy-ucomm.

DATA save_ok LIKE ok_code.

........

........

MODULE user_command_1000 INPUT.

save_ok = ok_code.

CLEAR ok_code.

CASE save_ok.

WHEN 'ENTER'.

........

........

ENDCASE.

ENDMODULE.

Now if you enter something in your I/O field and press enter then data wont get cleared.
