Hi John,

When you want to call the function when you press enter,

you need to keep the function code of the button used in that screen as enter and write the code regarding that in the PAI of that screen.

OR

If you want the functionality to happen when you press enter,then check the function code of enter in the debugging and put that value in the cases you write in the PAI module.

Reward if useful.

Thanks & Regards,

Khan.

Hi John,

You are not getting any value in SY-UCOMM when you press "Enter",because the function code is not set for 'Enter" key in "Function Key" of the GUI-STATUS..

First define some fucntion code say 'ENT' for the Enter button available in "Fucntion key" of the GUI status.Once you done and activate the program and test it.The function code which u defined will be coming to SY-UCOMM field when you press 'ENTER" button and you can handle the various fucntionality whichevcer you want on "ENTER" .

Eg:

case sy-ucomm.

When 'ENT'.

..............

..........

Endcase.

the only way for this is to use the sy-ucomm and clear before it is calling ...then there is nothing to bother ...

check this ..

case sy-ucomm.

when 'ADD'.

write some thing to do..

when 'DEL'.

write some thing to do..

endcase.

Hi John,

Following snippet might help:

In PAI section

V_FCODE = OK-CODE.

CLEAR: OK-CODE.

CASE V_FCODE.

WHEN 'BACK' OR 'EXIT' OR 'CANC'.

LEAVE TO SCREEN 0.

WHEN ' ' . " for <enter>

"Write your validations & processing here

ENDCASE.

Cheers,

Vikram
