Most work stack types offer the ability to filter to see only your own records, with the My Records option under View Mode.
Service asset work stacks offer an additional option when My Records has been selected.
The View Mode Options menu lets you choose between two additional modes:
My Assets - Show assets of which you are the owner
My Customers' Assets - Show assets belonging to customers of which you are the owner
Which option you should select depends on your preferences and processes.
