Adding a New Label
Open the field definition in the definition workspace.
To add a new label, enter the label ID, long name, and short name in the last row. Each label can have related language labels. After defining the multiple labels, you can select appropriate labels when designing a record or page. You also can specify different labels in PeopleCode. To add a line feed for Long Name and Short Name, enter \n (backslash and the letter n). For example, work \n month adds a line feed between the words work and month.
When you create multiple labels, the first label ID is the default label . You can change the default label by selecting the Def check box for a different row. Only one label can be the default.
Note:
Each label ID must be unique so that each field definition label can be identified separately, and it must be entered using uppercase letters with no spaces.
