IBM InfoSphere Master Data Management, Version 10.1When you create a data type property of type Reference Data Set that points to a data set in the system, the options available must be from a current version of that set. A current version of the set is required to fill that property in a reference value.
The current version of a set is one that meets all of these conditions:
If more than one version meets these conditions, the most recent version is considered the current version.
You create a reference data set called Countries, which contains reference values for country names. The State for the Countries data set is Approved. Its Effective date was last month, and its Expiration date is next year.
Next, you create a reference data type called Branches, which includes a Value Level property called Country. The data type for the Country property is Reference Data Set, and its Related set is the Countries reference set.

When you create a reference data set called Branches, basing it on the Branches reference data type, the Country property is populated with the values from the Countries data set.
