By default, the creator of the data source
is added with an Editor role. Also by default, Authenticated Users are placed in the
Reader role if the developer checked the box (shown in Figure 5-4) granting Read
permissions to all users. If not, everyone should have Read permissions through
this data source, which means that the particular role can be removed and a more
restrictive one added. Also, additional roles can be added if more editors are desired.
New roles need a user in the format of DOMAIN\alias, where the alias can be an
individual user or an NT group. Figure 5-6 shows what this screen might look like
with the addition of a custom property and a description of the data source.
Figure 5-6 The Properties tab of the data source sets general and custom properties,
along with permissions for who can read and who can edit the data source.

The Time tab allows users to select a member in the cube??™s Time dimension and
map it to a date in the Dashboard Designer??™s Time control. Developers can assign
the levels in a time hierarchy to associated levels in the Dashboard Designer, which
enables the use of Time Intelligence Filters across the cube. The Time Intelligence
Filters allow developers to create filter selections such as Last 6 Months, Last 4
Quarters, and more, all of which can be based on the current date.
