Error 'The value is not a cube.' while refreshing data
I created a report based on local CSV-files and SAP BW queries. When I refresh data in Desktop, it works totally fine. However, when I schedule a data refresh in the Service, I get notified that 'The value is not a cube' and it relates to a table ("Lijst met afnemers") that is based on a SAP query. This is the error: Again, in Desktop the refresh works totally fine.
I can't find any documentation on this error, so I am hoping anyone here can help me out.
