Unable to open AFO workbook connecting to HANA

Hi

I am having issues opening a published AFO workbook in Business Objects. This AFO workbook reads off a calc view in HANA.

When I open the workbook, I do not get the variable screen to enter the parameters. Also if I open the design panel, I see the free characteristics but nothing in the rows and measures. If I refresh the report,I get the following error "Datasource assignment is not complete"

When I close the AFO workbook and exit, I see this error message on the BI Launchpad screen:

Not sure what is the issue here. Can anyone help?

Thanks
