If we have an AS Azure model with security affecting measures (hiding security columns that measures are built on),
then, when executing mdx relating to measures
e.g.,
Select
[Measures].allmembers
on axis(0),{} on axis(1) from [Model]
we get an error
Error: An unexpected exception occurred
if we reach members explicitly, e.g. {M1, M2} we do get them back
This works well for an admin user and fails for user belonging to relevant role
