Which of the following is a function of Portlet Scripts?

Portlet Scripts are specifically designed for creating customized portlets within NetSuite. This function allows users to design portlets tailored to their unique business requirements, enabling them to display information or allow data entry in a way that fits seamlessly into their workflows. Custom portlets can enhance user experience by presenting relevant data in a visually appealing format or providing forms for data input directly within a dashboard.

Custom user interfaces, while related, are a broader concept and not exclusively tied to the capabilities of Portlet Scripts. Automating bundle installations and executing batch operations do not align with the primary role of Portlet Scripts, as these tasks involve system-level functionalities rather than user-interface customizations. Therefore, the ability to design custom portlets specifically for displaying data or facilitating data entry accurately defines the core function of Portlet Scripts.
