Hi @Rowen,
What’s the total string size when you add all the departments together? And, curious, what’s the cardinality of departments and what’s string size of the department field?
I’m guessing that you’ve already seen this work-around: RLS by pass the limit of 256 per tags
One thought might be to introduce a higher level grouping, so some category that already includes the right departments and facilities. So the hierarchy would look like System → Group → Facility-Department->Category. I don’t know that would work with your data or not, though.
Thanks!
