747 Route Offset Issue

[Guest B1900 Mech]

Hi all:-) I am having an issue while flying a route offset in LNAV. Are any route mods not allowed? For example, a runway change? I loose the offset,and am not able to imput one again. Also,how often is this used in real world ops? With the precision of today's INS, I would be using this function if I were the captain.:-) Thank's for the great product!

You can change/add/delete legs, change the Arrival runway at anytime during flight.Are you forgetting to Activate the changes? The EXEC(UTE) button?
