Dear SAP Gurus,

I'm new to SAP-BI, I came across the following situation:

I've a query based on which the reports are being generated.

My client wants to broadcast it every month, as they don't have any portal, so it has to be done through e-mail.

the query has 3 system variable which are FISCALYEAR and CALDAY, i dont remember 3rd.

So, I've to create DYNAMIC VARIANT, I tried the following procedure but its not working.
