When you work with dataset attribute groups, be aware of
the following additional requirements that apply.
Dataset name masking rules
The dataset name property supports the use of mask characters.
Asterisks (*) and percent signs (%) can be used to represent qualifiers
or parts of qualifiers in dataset names.
Dataset attribute groups and the Dataset Attribute Database
Dataset attribute groups access the information in the
complete Dataset Attribute Database to determine the data sets that
match the criteria specified in the groups. When a Dataset Attribute
Database collection cycle begins, the information associated with
each group is cleared and is updated upon completion of the collection
cycle.
Dataset Attributes Group Details 5,000 data set limit
Although a dataset attribute group can aggregate the metrics
for more than 5,000 data sets, the Dataset Attributes Group Details
workspace returns the details for a maximum of 5,000 data sets.
