Hello Peter,
as a quick alternative you can just create a new application configuration under application GRAC_OIF_ERM_ROLE and assign the standard OIF configuration to it.
To start the application with the new application configuration you have to right-click the newly created application configuration in SE80. Or you add as URL-parameter &sap-wd-configId=<NAME_OF_APPL_CONFIG>. That's it.
Best regards,
Julia
