Handling BUTTON_CHOICE events from standard FRIEGHT ORDER screen.

Hello Experts,

I need to disable the button choice menu option on the standard screen of the Frieght Order.

I have created component Customizing of the  FPM screen /SCMTMS/WDCC_FRE_ORDER. In  the cusotmizing, I have added button_choice on the toolbar. I have added to menu options to it. My need is to disable one of menu options based on value of one of the fields of the screen.

Also, on click of the options I will be calling some class method to change the status of the FO/FB.Service ORder.

As I am just learning the TM module. I am struggling to achieve this requirement.

Please provide your valuable inputs on this.

Thanks in advance.
