Newly generated account not selectable in account moves

I am using the German skr03 chart of accounts. However, account 0800 is missing. I generated it and it is visible in General Account > Accounts > Accounts.
When I try to use it in a new account move it is not selectable in the position line.
What am I missing?

An account should have a type to be used.

Please fill a bug report with the required information to add it.

THX Cédric, when I add a Type on the ‘General Information’ tab, the newly created account becomes usable in account moves.
