Thanks @Olga and @klincecum, that looks like it should be a good workaround for my use case!
I am still gonna keep after support on the REST method though. If it should be returning more than it does it’s broken. If it’s some kind of security or process that’s attempting to limit scope that’s not working correctly or consistently either.
OData REST is just built on top of GetRows. So it returns whatever that method returns. If it is not what you want, you have to use another method.
I can’t get my ODATA REST call to return jack no matter what I do.
I think there is something wonky with it.
what is the url you call?
Hold on, I’ll go do it again.
I was here: /server/api/help/v2/odata/Ice.BO.menuSvc/index.html#/OData/GetRows_Menus
But today, it magically worked fine.
It is GetRows custom method, not odata. or not. 
your link it to help page, not REST call, so I am not sure
Yes, that one always returned properly. I couldn’t get the ODATA one to return, so I couldn’t help him.
It works now, which is good, and probably means I’m an idiot.
