We have situation with external company layer service that is included in Web Portal map. This layer service provide some environment data that changes frequently (e.g. 5 per day). We want to have the data included in ArcGIS Collector offline mode - as a read-only, supporting layer.
But we do NOT want to copy & synch. data from external service to our own ArcGIS database several times a day, add GlobalID&Archiving (by following SDI principles we try to use referencing instead of unnecessary copying). Of course, we cannot change the external service layer (to add GlobalID etc)
Is there no way to get such layers on Collector ?
