It's second time i hear that there is question about loading data from sharepoint... I'm wondering if it's possible.
But as far as i know - is sharepoint is complex of software for frontend sites developing? And IT uses data from some other sources. Like sql server. So why not to take this data directly from this sources?
You can pull the data from SharePoint. The caveat would be, you can pull the data from the files stored in Qliksense. Any files supported by QS can be stored in SharePoint. Thus they can act as source.
You would require Qlik Connector. The beta version of connectors can connect to the QS and load the data from there.
