Tables and Columns get added/modified with every update/release. And there isn't a single place where we can get this information. We have to navigate to Common Features tables and HCM tables to get this information. And the search page doesn't provide an exhaustive search feature. We tried to simplify the process by providing many advanced search features.
Use the menu Navigation Bar "Tables and Views" to check the features of this application.
1) Tables Dashboard - Overview of Tables
2) Table Search - Search for Tables using Advanced Search
3) Table & Column Search - Search for Tables and Columsn using Advanced Search
4) Table Details - Lists Table Details along with Columns for Input Table Name
5) Column Details - Lists all Table References for the Input Column Name
The tables list has been updated till 21C. Please do your due diligence.
