One or more cloud data sources for this dataset have been deleted. Recreate cloud data sources

Hi SJ545 ,

I would suspect this is happening because when you take over a cloud dataset the previous credentials were linked to the user who owned the dataset.

Check the datasource in Manage Gateway or you need to remap the dataset to it in gateway connection.
