Note that you can’t access Pooled tables directly and it should be accessed via Application server. When a pooled table is created, it involves creation of a suitable transparent table with a suitable delivery class and then it is changed to a pooled table.
A pooled table can be flagged as transparent in its technical settings, which is a simple way of transforming it to a transparent table.
To fetch information from Pooled tables, you need to write an ABAP code that can extract the data as per requirement.
