1. NetSuite Help Center
SuiteAnswers. Topic: "Viewing Support Cases"
Doc ID: 90004.
Reference for B and D: This official documentation states
"You can view your support cases in the NetSuite Account Center. To access the NetSuite Account Center
go to the SuiteAnswers home page and click the NetSuite Account Center link in the header. You can also add the NetSuite Account Center portlet to your dashboard for quick access." This confirms both the SuiteAnswers path (B) and the portlet path (D) are correct methods.
2. NetSuite Help Center
SuiteAnswers. Topic: "NetSuite Account Center Portlet"
Doc ID: 90005.
Reference for D: "The NetSuite Account Center portlet provides convenient links from your dashboard to the NetSuite Account Center... Links may include: ... View Support Cases". This explicitly validates the portlet as a method for accessing cases.
3. NetSuite Help Center
SuiteAnswers. Topic: "Case Management"
Doc ID: 89988.
Reference for A (Incorrect): This document describes the setup and use of the Case Management feature within NetSuite for tracking support issues with a company's own customers
distinguishing it from the process of seeking support from NetSuite.
