Yes, Sy-UCOMM is the way to go. You need to have function code for each button presses, similary for ENTER also there should be a function code which will come into SY-UCOMM.

Hi Jesus,

Yes i think you can use SY-UCOMM.

CASE SY-UCOMM

When 'SAVE'.

WHEN 'EXIT'.

WHEN OTHERS.

ENDCASE.

If you want to capture specific actions mention them in the when clause. For other undefined keyboard actions put it under OTHERS option.

Cheers

Hi Ravi, what if im not going to press any button. the cursor is positioned in an input/output field when I press the enter key in the keyboard. when i try to check the sy-ucomm, it is empty.

In your PF-STATUS, the menu, you should have placed the ENTR function code for the tick mark button.

Only then it will work.
