Analyis Authorization, sometimes : is fine sometimes * is needed

Hello,

Ran across this issue a few times.  Lets say a report is being secured by 0PLANT (where we will created AAuths with specific plant values), and that report is coming off a Cube where 0COSTCENTER and 0COMP_CODE is also auth relevant.  We don't care about those and most times a : will suffice as a value.  But this time the report runs fine with a : for 0COSTCENTER but we get an auth error on 0COMP_CODE because a : won't suffice, the logs say that the system is looking for a *.  The message is: "AND 0COMP_CODE LIKE *"

Any reason for this?

Thanks,

Tom
