When you run the plan that creates the data set, you become the owner of the data set. A data set owner and the domain administrator can add users and user groups and assign the required level of access. You can access data sets based on the permissions that you have. If you do not have the required permissions, you cannot open data sets that appear in search results.

Data sets have the following levels of permission:

Read
Write
Execute

To perform any task that uses the data set, you must also have the minimum required level of privileges as a TDM user.

The following table lists the permission levels, the tasks that you can perform with each level, and the minimum required privileges for each task:

Permission	Description	Minimum Required Privilege
