Select Input Source — Users may select between different sources of input.
By selecting the Input Source Table, the user can select from available databases, tables (or views) and columns in the usual manner. By selecting the Input Source Analysis, however, the user can select directly from the output of another analysis of qualifying type in the current project. Analyses that can be selected from directly include all of the Analytic Data Set (ADS) and Reorganization analyses (except Refresh). In place of Available Databases, the user may select from Available Analyses, while Available Tables then contains a list of all the output tables that are eventually produced by the selected analysis, or it contains a single entry with the name of the analysis under the label Volatile Table, representing the output of the analysis that is ordinarily produced by a Select statement.
