F9K3 and authorization object in su24

Hello,

We want to add authorization object F_KNA1_BUK to new role for check in F9K3 transaction.

The problem is it is not being checked. I tried to debug and stop on authority-check but it's not stopping on this object.

But the object is showned in transaction SU24 - as CHECK / NO.

So it should be checked during F9K3 transaction run, correct?

Anyone knows what we're missing here ?

Thank You in advance for help,

Best regards,

Artur
