Can someone please point me to the documentation for situations where a global id cannot be added to an individual table or feature class? 

Looks like you cannot add it to a feature/table that is in a geometric network 000582 : Error while adding Global IDs 

I am trying to add it to a feature in a dataset that is:

• not versioned
• not in a network
• does have a number of relationships
• is in sde

I am getting the 000528 error with python. If I try with ArcCatalog the option is not available. However, it is available at the dataset level.
