Hi @ManojkMohan ,

You need to assign a correct set of grants to your service principal on Unity Catalog. 

To query a table in Unity Catalog you need at minimum following privileges

- USE CATALOG - on the parent catalog of the table

- USE SCHEMA - on the parent schema of the table

- SELECT on the table itself

So, could you assign those permission to the Service Principal you're using to connect to databricks in Salesforce?
