Use
You can only block a certificate profile if it has no assignments from the current date onwards. You can remove assignments from a profile by allowing the validity period to expire before the current date. If a profile is blocked, you cannot assign an object to it until you remove the block (that is, until you release the profile).
Procedure
Note that the system status in the General data section has changed to LKD (blocked).
