Many of the pages allow you to put in the same kind of information multiple times within a single record. For example, by default, the following pages have batch appearance and functionality:
•Categories
•Relations and Involved (in projects and contacts)
•Assignees (in projects)
•Invoice Line Items
•Batch Tasks and Batch Expenses
•Attendees and Resources (in appointments)
•Address, Phone, Fax, Email, Internet Address, Skills, Rates, Territories (in contacts)
Initially the Phone section in the Contact record has only a single entry available.
To add more entries, click the Plus button that is shown to the right of the input fields, one or more times.
Now the section contains multiple entries, all still blank. You can edit all of these entries.
