    Large Partitioned Data Set
    The options in this area determine how large partitioned data sets are handled in the Remote Systems view.
    Default expansion page size

    Show warning message on expansion
    Select this check box to display a warning message when expanding large partitioned data sets, which can take a long time.
    Maximum number of members expanded without warning

    Maximum number of members added to subproject without warning

    Select this check box to display a warning message when you delete a data set alias.
