Datacom Table Usage
The Datacom Table Usage tab lists the Datacom tables that are used by the application. Nodes in the Datacom tab represent the different statement types that refer to the tables (ADDIT, LOCKX, UPDAT). For each statement type, the references in the source code (file name and location of the reference) are listed.
To display the Datacom Table Usage tab, go to Explore Projects and select Datacom Table Usage from the Usage in Programs list of analyses to the right of the screen.
The central part of the screen displays the list of attribute filters. By default, all attributes are selected; deselect the ones that you do not want to use. The breadcrumb displays the selected projects, the selected attributes in the set order together with the filters set for each attribute
