Hello!
I have a scontrol that clones an Opportunity and all related lists, including the Partner Object.  Because the Partner object cannot be queried by standard users, I am querying the OpportunityPartner object, which is supposed to be accessible by all user profiles.

The error is 'Invalid_Type: sObject type 'OpportunityPartner' not supported.  I get this error with both a SysAdmin and Standard User profile.  If I switch back to queryiing the old 'Partner' object, it works, but only with a SysAdmin profile.

Any help is appreciated!
