EBS Invalid Object Utility (Doc ID 2214169.1)
The E-Business Suite Invalid Object Utility displays all invalid objects and meta-data in a single HTML Report. There is a quick view summary of all invalid objects, their types and schemas. You can cross-reference your current list of invalids with known objects from the Upgrade Guide of Droppable Objects. And, you can cross reference DBA_OBJECTS.TIMESTAMP and AD Patching tables to show objects creation date/modified date in relation to the last 100 days of patches applied. This feature provides insight on which patches might have caused the invalid object.
