As per the documentation, GTREP Repository user need all below Privileges:
Release : 4.9
Component : CA Test Data Manager - Others
Due to security reasons the DBA is not willing to give all the permissions and would like to know the minimum set of permissions for GTREP user in Oracle.
The minimum permissions to start with which we have tested the GTREP to work are listed below. During usage if need arises based on the use case, we may need to add more permissions.
grant create table to gtrep;

grant create view to gtrep;
grant create procedure to gtrep;
grant create trigger to gtrep;
