MD-11. Why "Not allowed" to access the LAT Rev page?

[Guest cliffie1931]

Page 8 of the Introductory Tutorial, when describing how to deal with the F-PLN page, instructs us to "Press LSK 1L next to EGLL to get you to the LAT REV page for EGLL.When I do so I get a message reading "Not allowed". How do we deal with this problem please? I've included an illustrative attachment. Cliff

You are on the F-PLN INIT page, go to the F-PLN page by pressing that key, then the LSB next to the origin to select SIDs for next waypoint.
