1. NetSuite Help Center
SuiteAnswers. "Submitting a Case for Support." SuiteAnswer ID: 9131. This document explicitly outlines the procedure: "You can submit a case online through the NetSuite Account Center... To submit a case online: Go to the NetSuite Account Center portlet on your Home dashboard and click the Submit Online Case link. OR Go to Support > SuiteAnswers. On the SuiteAnswers home page
click the Contact Support Online button in the upper right." This directly supports option D.
2. NetSuite Help Center
SuiteAnswers. "NetSuite Support." SuiteAnswer ID: 72221. This article details the various support offerings and emphasizes the online case submission via SuiteAnswers as the central method for contacting support. It does not list the other options as valid channels for technical support.
3. NetSuite Help Center
SuiteAnswers. "Standard NetSuite Roles Permissions." SuiteAnswer ID: 8991. The documentation for the "Employee Center" role confirms its limited permissions are focused on employee self-service functions and do not include permissions for "Support Case" management
which validates why option A is incorrect.
