When a party has a stand-alone protection order, you can link that protection order to a case.
From the
Prot. Orders tab on a case, select a party and click

to access the
Link Protection Order dialog box.
From this dialog box, you can select the protection orders you want to link and click Save (ALT+S) to add them to the case. A warning message is displayed prompting you to confirm the addition of the protection order.
Click Yes (ALT+Y), and the protection order is then listed on the Prot. Orders tab.
