Out org has some managed packages installed.
When we try to generate the enterprise wsdl, only some of them appear on the list of packages (so we can set the version). Custom fields on the packages that aren't on the list don't show on the wsdl.
p.s.: We already tryed making SOAP calls to our org and we were able to fill those fields. Also, FLS is set as visible to all profiles.
Is there anything we're missing?
