MCDU Message 'Enter HDG/TRK First'

[michael1508]

Hi all,

I wanted to add a waypoint during my flight.
I have inserted it as next waypoint on my route, but couldn't save it. The following message appeared on the MCDU: "Enter HDG/TRK First".

Choosing HDG/TRK on the FCU didn't help. What am I supposed to do?

Thanks,
Michael
