Working day formula that excludes weekends and holidays in WEBI

Hi Guys,

Can we calculate a working day formula that excludes weekends and holidays in WEBI OR in Universe?

The universe I am working on is using stored procedures, so there are no joins or modelling done. Although there is a workday stored proc that I can bring in the universe.

I am just thinking if there is no modelling or joins done in the universe how will this help me in webi?

Your suggestions will be very helpful.

Thanks,

Jitan
