Above is the accrual chart for LH's P fare (discounted business), and it's very illustrative for LH's stance towards that particular airline.
Why is LH in *A if they don't know what "alliance" means?
It's not only Lufthansa and Star Alliance who are doing this.
There is an example at SkyTeam as well, Air France discounted Business Class "O" fare does not earn miles on most other SkyTeam partners.
If you would like to fly Lufthansa Discounted Business Class, this means that you need to either pay the difference with "Z" fare bucket which is non that much in intra-European routes ( maybe about €100 on round-trips ) or decide not to get miles when using another *A FFP that does not give miles to LH "P" fare bucket.
