I set up flight profile both departure and arrival PFPX set up stars and transitions, problem is when approaching glideslope intercept CDU does not automatically pick up arrival airport runway ILS identifier or frequency. Tried entering ILS frequency and identifier manually, CDU will not accept inputs. Maybe I am missing some actions either in operation or flight planning, have tried generating same plan in FSC and PFPX, get same result with both plans. Have followed instructions with regard to documentation, but still no joy, has anyone had similar circumstance, or know what to do?
