Screen exit (VA42) Additional Data B screen

Hello all,

I have created a button on additional data B screen of a contract (VA42) and have written code in its PAI to update some database tables.

The update takes place properly but after clicking the button the screen goes in display mode and gives the error message as 'Requested function SET is not available here'. (SET is the function code of the btn created)

Please suggest some solution for this.

thanks in advance.

Regards,

Neelambari.
