HMRC internal manual

Collection of Student Loans Manual

background: features of SLS: view functions

In many HMRC computer systems it is not possible to access a record to view or update when another operator is using that record.

The Student Loans Service (SLS) does not have that restriction. This means that if you have the appropriate user role you can view a record although someone else is currently updating that record.
