Activities: In Microsoft Dataverse, a Task is a type of Activity entity. To create a record, a user must have the Create privilege. However, for the user interface to function correctly (allowing the user to see the record they are creating or have created), the Read privilege is also required. Without Read access, the application would encounter "Access Denied" errors during the post-creation redirection or viewing process.

Assigning Cases: The Assign privilege allows a user to change the ownership of a record. To ensure HR users can assign any case record to other team members, regardless of who currently owns that record, Organization-level (Global) depth is required. User-level depth would restrict them to only assigning records they currently own, which would fail to meet the requirement for a general HR workload distribution.

Microsoft Learn (Official Vendor Documentation): Security roles and privileges. Section: "Table privileges." This documentation specifies that the "Assign" privilege is required to give a record to another user and "Read" is necessary to view records in the UI.

Microsoft Learn (Official Vendor Documentation): Activity tables. Confirms that Tasks, Emails, and Phone Calls are part of the Activity entity suite and inherit security from the Activity pointer or specific activity tables.

Microsoft Dataverse Security Model: Privilege levels (Depth). Defines Organization (Global) as the level providing access to all records in the organization, necessary for administrative or departmental oversight roles.
