In this article we will look into the links to the Oracle Documentation which are very useful to the developers or end users.
First we will look into the Tables and Views Documentation available. For every release 20A, 20B, 20C, etc Oracle releases the list of tables and views with the updated list of tables (some tables could be added/modified). The tables and views links are listed module wise and each pillar (HCM/ERP/SCM/PPM/CX) has different links. Apart from these multi pillar links we also have Common Features links which are common across all pillars like lookups, valuesets, messages, FND tables etc.
We will look into the links specific to HCM for the latest release in this article. The below links are specific to release, however you can modify the release name in the link and if the documentation is available for that release it will take you to that link.
