SAP BW Query connected to a WebI Report - BW Variables not passed

Hi,

I am currently using BOE XI 3.1 SP3 and SAP BW Query to pass data to a WebI Report via Universe.

My understanding is SAP BW Variables would automatically appear in the webI report but this does not seem to be the case. I have got some mandatory and optional variables in the query and when I execute the WebI report they dont seem to be called - the report just runs as usual.

The only one that does seem to be called in the "Query Key Date Variable" - for master data.

Anyone help?

Thanks
