Passing parameters from Design studio to Hana View based Webi report via Opendoc

Hello,

I have a requirement where in I need to pass value selected for mandatory prompt Calendar month from Design studio to a detailed report in Webi. This variable is part of a HANA calculation view and is setup as Interval type. I have captured the selection in DS app but am finding it difficult to pass this selection to the webi report built on top of the same Hana view. I have tried to pass it as range, single value in the opendoc url but I am not able to do so. Has anyone come across this sceanario. Any suggestion/inputs?

DS - 1.4

BOBJ - 4.1 SP4

Thanks
