When a case is assigned to you, if you cannot work on the case immediately, you can park the case. When you want to work on the case you must then retrieve it. For information on retrieving a case, see Retrieving a parked case. Parking a case is a little like putting a call on hold except that parking a case leaves you free to deal with other cases in the meantime.
To park a case, when the case is assigned to you and pops in Service Cloud, in ContactPad click Park. You are released from this case in ContactPad, your state changes to Ready, and you can work on other tasks.
The parked case appears in the queue information panel in ContactPad.
