There are a few different accounts and contact records used with Oracle Service Cloud. Can you please clarify the purposes for each account?
There are different accounts used in association with the Oracle Service Cloud. It is important to use the proper credentials when accessing the different areas of the product and self-service tools. Below is an overview of the different accounts and their purposes.
Oracle Service Cloud application
The contact record is used to log into the end-user pages of our Technical Support site (cx.rightnow.com). There are many options available on our end-user pages. One of the main options is the ability to submit a service request (ask a question) to the Oracle Service Cloud Technical Support. There are different types of contact records (Primary Support, Technical, and KB-only) and different levels of privileges (manage contacts, designated support, and community).
The staff account is used to access the CX desktop console of your site/instance. This is where administrators can configure and manage the site. Non-administrators can access the CX console to perform tasks such as address incidents, Chat, run reports, etc. Oracle Service Cloud Technical Support is not equipped to manage staff accounts on our customers' sites.
If you are logging into your site for the first time there are no pre-existing staff accounts. You will need use the system-defined administrator account.
