Data selections are always evaluated at run-time so they are always dynamic and depend on

There are several types of data selections you can use, depending on which emulation you are
using, whether or not Metadata have been created by a previous task in the process, and
whether or not data have been entered in the Data Repository.
Adding a data selection
A data selection can be used in any task property that may contain a variable. These properties
are recognizable by their colored field label (maroon, by default). Right-click the property field
and choose Get Data Location or Get Metadata Location to open the Data Selector (see "The
