Hi,

Good luck

No.Field exit can not debug. Field exits have to be tested in isolation in the development environment. To analyze problems that occur only in the screen environment, the relevant variables can be written to the file system using TRANSFER... and can be analyzed there.

Check whether you have assigned a value to the OUTPUT field.

The following ABAP statements are not allowed in the function modules of field exits:

BREAK-POINT,

CALL SCREEN, CALL DIALOG, CALL TRANSACTION, SUBMIT,

COMMIT WORK, ROLLBACK WORK,

COMMUNICATION RECEIVE,

EXIT FROM STEP-LOOP,

MESSAGE I, MESSAGE W.

Hi again,

I am entering the outline agreement no. in the item list.

When I press enter it should display the amount corresponding to the no. Till this step its going fine however when by mistake an enter is pressed again it takes amount as outline agreement no. and output is going wrong.

I tried writing Field Exit for the same but didnt help much. So I have taken up writing a BADI. Can anybody tell me a BADI for subscreen(Item List).

Thanks,

Hi Rinku

You can put message 'E' statement in your field exit and display the values in message statement. this is the good way of debugging field exits.
