I have a tcode ME22n (Function Grp IPW1) serial number popup (screen 0300) with 9 buttons. However, it is not showing the function code +ZUD, yet it is defined for the Gui Status SNH? Furthermore, in the PAI of screen 0300 in MODULE ablauf_liste it has ok_code check that will do a PERFORM fcode_zud. I like to know how to get this button to show since it is active and use it to Import Serials. Also, 1) how did you add your custom buttons to MB52 2) isn't that a core modification?

Thanks, Pete
