Scenario: User needs to create a custom category for the center tab.
Solution: Go to Customization > Center and Tabs > Center Categories > New.
On the Center Category page, complete the following steps:
In the Label field, enter a name for the category.
In the ID field, enter an ID for the category, if required.
From the Center Type list, select an existing center.
From the Center Tab list, select one of the standard, built-in NetSuite tabs (also referred to as sections).
From the Insert Before list, select where you want to insert the custom category.
On the Values subtab, in the Link list, select the appropriate link.
The links that appear in the lists are links to other NetSuite pages, custom records, Suitelets, and external web pages. Links to NetSuite pages, custom records, and Suitelets appear by default.
To select a link to an external website, you must have already created that link by going to Customization > Centers and Tabs > Center Link. After the link is created, the link appears in the Link list.
In the Label field, enter a UI label for the link.
The short list setting is applicable to some center types. In the Short List column, to indicate that the link should appear in a portlet when the link is in a narrow column of the dashboard, check the box.
Click Add.
Click Save.
