Hi Alirezam ,

If your dataset not only contains cloud data source but also the on premise data source, then you may tick the  "Note that you also need to select Allow user's cloud data sources to refresh through this gateway cluster" option Under Gateway Cluster Settings. See: Merge or append on-premises and cloud data sources.

Best Regards,
