Shelve and Unshelve a WCU
Using the buttons presented in Figure "Shelving Buttons" can be used to "Shelve" and "Unshelve" a WCU, respectively.
When a WCU is shelved it is disconnected from its car, if connected, and removed from its resource group, if any. To mark its status one of the two system labels shelving_in_progress and shelving_done is attached. If one of these labels are present for the WCU it is also possible to "Unshelve" it using the so named button. If not "Unshelve":d, the shelving_in_progress-label will remain until all tasks for the WCU have status Stopped and all gathered measure data is uploaded to the portal. If this process is aborted or if new tasks are added to the WCU with shelving in progress, this label will never be replaced with shelving_done. It is, however, still possible to "Unshelve" the WCU.
It is possible to both "Shelve" and "Unshelve" multiple WCUs simultaneously. If one of the choices does not apply to the set of selected resources, the corresponding button is disabled. If both buttons are enabled, as in the Figure "Shelving Buttons", it means that there are both "Shelved" and not "Shelved" resources within the selected set. Selecting either will only affect the WCUs which are not already "Shelved"/"Unshelved".
