Which feature allows for the addition of multiple fields in a saved search?

The feature that allows for the addition of multiple fields in a saved search is the multi-select pop-up window. This pop-up provides users with the capability to select numerous fields from a list, streamlining the process of customizing the search results. The multi-select functionality enhances the flexibility of saved searches, enabling more complex queries that include various data points relevant to the user’s analysis or reporting needs.

Using a multi-select pop-up window makes it much easier to visualize and select the fields you wish to include without navigating through different menus, thus improving the efficiency of creating saved searches. This tool caters to users looking to gather comprehensive information from diverse data sources within NetSuite, allowing for tailored reports that reflect the specific analytics desired.

While the other options like a dropdown menu of field options, standard field list only, and custom field entry fields have their respective uses and benefits, they do not provide the same level of multi-selection capability inherent in the multi-select pop-up window.
