Customizing Browser Tab Labels
Hello,
Bookshelf describes how we can configure Open UI browser tab label. The bookshelf description is incomplete:
Siebel Open UI uses the view Title that you define in Siebel Tools to set the Browser tab label. If this Title is not defined, then Siebel Open UI displays the Id of the current record as the label. For example, it might display 2-HB474 as the Browser tab label. If the label is not set for the view, the Id of the selected record is displayed by default.

In reality label consists from 2 parts.
