This is an easy one!
If you manage multiple FCA-registered entities, you can easily switch between them to manage individual parts of their compliance. To do this:
Look at the top-right hand corner of Corterum, you should see your Company name, with a dropdown arrow next to it.
Click the dropdown arrow and the Switch Company screen will pop up.
Select the correct company from the dropdown list and Corterum will switch to the data held for that company.
The top-right hand section of the screen will always show the current company you're working on, so you can see at a glance where you are. If you can't find a piece of information you're looking for, it's worth checking to see if you're administering the right company!
