Which Role to be assigned to grant Data model access in OTBI My Folder alone & not shared folder

The user does not have oracle.bi.publisher.developDataModel permission. 

The ability to create a data model is controlled by an OBIEE role named developDataModel. In Fusion Applications this role was included in BIAdministrator and, therefore, users can only create or edit a data model if they have BIAdministrator role. There is an enhancement request open to allow developDataModel to be assigned outside of BIAdministrator because BIAdministrator allows access to other things, too. For example, it allows access to report destination set up information. The enhancement request is 16173773. It is an internal enhancement request so it is not viewable by customers.
