BPM Advanced User Privileges in Epicor Functions? (Need to run BitConverter)

I find myself needing to convert a byte SysRevID to an Int64 in a function, but expression editor is telling me that I need BPM Advanced User Privileges to run BitConverter. The thing is that I already do. Do I need to do something else to enable me to use BitConverter in a function?

I just did what I’m sure most of the people in here would do and figured out how to do the conversion with code instead of expression editor, which worked fine.

I didn’t realize at first that the error said I couldn’t run BitConverter in expression editor, not that I couldn’t do it at all.
