AU will scan the JCL in your MVS job libraries and load the information into the AU Inventory database on your workstation. It will process your entire shop, or you can include or exclude applications using a pattern filter. The extracted information is formatted in CDIF (Common Data Interchange Format), a human-readable format, so you can read, modify, and augment the information, such as adding information on source and object code location, before loading it into the database.
Once the database is loaded, all the information is available for the View Facility.
In AU, group your applications into inventory groups by using a simple GUI to pick and choose the applications for the groups. The groups can help to organize your work, perhaps along work-group lines, and are useful for tracking purposes. The groups can overlap.
