User is unable to edit a table on a remote Subsystem.
To reference the remote SSID, the LOCSSID and LOCATION fields under the Source SSID in the SETUPxx member of
the hilvl.Parmlib dataset must be referenced.
In addition, when accessing the RCU product from the Main Products menu the LOCATION must reference the LOCATION of the remote SSID as it is defined
in the LOCATIONS table.
