Are you using ECAS (CIC check Status) or GCMS (myCIC)?
ECAS: If you use the Application Number, the Sponsor's Surname / DOB / Country of Origin you will see both the PR application and the Sponsorship applications. If you use the Principal Applicant's Surname / DOB / Country of Origin you will see only the PR application (assuming you can see it).
myCIC: You will have to create an account, then you can search for the application and link it to your myCIC account. This is better because you will get a little more detail, and it will notify you when your application changes.
