Dataset Attributes Dataset Detail

The Dataset Attributes Dataset Detail attributes provide data set information from the VTOC and catalog. The attributes in this group include details regarding control intervals (CIs) and control areas (CAs). See Dataset Attributes Database for more information.
Note: You can create queries and situations that generate more specific data than that provided in the default workspaces. Be aware that in a large enterprise the data set database can be tracking millions of data sets. Estimate the potential size of the responses to your queries and situations to prevent them from requiring excessive processing, network, and disk space resources. Also be aware that a maximum of 16384 rows are returned on any single query against the Dataset Attribute Detail table.
