Modifying Business Service Method for Existing Toolbar Button
If you have created a custom business service, and you want an existing communications toolbar button to invoke a method for this service, then you must use Siebel Tools to modify the command object definition that is associated with the toolbar item, to specify the new business service and method. This approach is of limited practical value, however, because you can customize the function of a button without using Siebel Tools.
For more information about how business service methods are specified for the toolbar buttons, see Communications Toolbar Items, Commands, and Methods.
