I have a customer that can't run a codeunit in the 50000 range. The ID is specifically 50005. They get a permission error.
Their license seems to have access to 10 codeunits, or at least, that is how I understand it:
The weird thing is that they have object ranges from 50000 to 59999 for every object type except codeunits:
How come they can't run the codeunit?
