Getting pop-up message in Webi report

Hi All,

My requirement is something like this. There is a date prompt on the report. When the date entered is either 1/1/2014 or 12/31/2013, then there has to be an message in front end Webi report saying no data to retrieve even though something comes up from backend.

Is it possible to achieve this.

Environment

BI 4.1 SP5

Back end is BW 7.4

We have 2 data providers to get current and previous year data.

Thanks,

Harsha
