The "insufficient privileges" error indicates a permissions issue. For users who only need to view and interact with pre-built Tableau Next dashboards and metrics, the "Tableau Next Consumer" permission set is the correct and most secure choice. It grants the necessary read-only access to Tableau Next content embedded within Salesforce pages, such as the mobile home page, without providing unnecessary creation or administrative rights. Assigning this permission set to the field sales reps will resolve the error.

A. The "Tableau Next Creator" permission set is for users who build and publish dashboards, which is an excessive level of permission for a field sales rep.

B. "CRM Analytics Plus User" is a permission set for a different, though related, product (CRM Analytics, formerly Tableau CRM) and does not grant the specific permissions needed for Tableau Next.

- Salesforce Help, Tableau Next Documentation, "Set Up Tableau Next", Section: Assign Permission Sets to Users. This document explicitly states that the "Tableau Next Consumer" permission set is for users who view dashboards.

- Salesforce Help, Tableau Next Documentation, "Embed Tableau Next Views in Lightning Pages". This guide notes that users must have the appropriate permissions (Consumer or Creator) to see the embedded views.
