After you have built and distributed, or even while assembling, a Package you may need to review the contents and definition. There are several ways to do this:
If you used Cross-referencing in conjunction with your Object Selection you can review the full list of objects included in the Package using the 19.1 Objects included in Package. Cross-referenced objects are only available after the package is built.
To search one or all Applications to check if an object was included in the Package use the 19.2 Search Application feature from the Options Menu.
If you want to review the options applied you will need to open the version or patch.
