Unable to access the tables from Oracle Database

Hi Experts,

Is there any restriction in Appian on a service account with read-only access on Oracle database, to not be able to create the CDTs using those table.

In my current application I have been provided with credentials for the account which has only view access for the tables. I have configured the connected system with provided credentials.

But when I'm trying to create CDT's I can only find the Schema Name but not the underlying Tables.

Please suggest.
