Your SAP ID is much like your apple cloud ID or googles account. It's something you own and manage with regards to passwords, emails, ID, etc.
To onboard a user, the first step is to create a new SAP User ID. Navigate the following website and sign up for your SAP ID.
Once complete, provide the SAP ID and email address to the Administrator of the SAP Cloud Application (RBI, Digital Wall Chart, etc..) and they will add you as a user.
