percent of grand total

[Krcmajster]

hi All, 

I have a table with a few measures and until now it gives me what I need but I've hit a rock because of filtering.

Below the table:

Tabe is split by region. First row is a measure (named CAT Cost) that gives above numbers and that's fine. Second is the same but as % of grand total. However I need this percentage of grand total in a measure as I need it for further calculation (to multiply it with other things). How I am using it it currently also filter by region and this is not what I need

Is there a way to do simple measure like this

CAT COST*/sum(CAT COST) to get percentage of grand total?

                *This will still be filtered by region

note that there are a few filters in the measure and on the page leve which I need to keep.

Can you just add the measure again, use the drop down in the Fields area and choose "Show as | Percent of Grand Total"?
