Catch Cross scope TABEL Assess Issues in Server Side Script - from Global any Scope

[SteweLundin]

Trying to catch when I get a Cross Scope issue when accessing a table from a script in global. 

All I want to do is know IF i cant access the requested table

If I do a GlideRecord or a GlideRecordSecure from Global to a Scope(any scope) where I have no priviliges there is no error thown. 
I get a legit but EMPTY GlideRecord - this alone is not sufficitent for me to catch as my result
- canRead, canWrite and canCreate  are return as true (using Admin). 
try {} catch(){} will not catch this. 

All I can see is a log entry saying that I have no Scope Priviliges. 

Any Ideas. 

And NO, setting up Scope Priviligies is NOT an option

GlideQuery can be used in a try catch and will throw an error if you're unable to write to a scope 

[SteweLundin]

That is not an option unfortunately!

Interesting restriction, hope you find a solution

Me to!
My "work around" at the moment is

If
!my_gr.hadNext()
and if application !=global

I will treat is as if I cant read it due to cross scope issues and it has to be checked manually or excluded from further exekutions.
