Filter a visual based on selected measure from another visual

I have a table which shows product availability and their forecasts.

I'd like to show ratio of "out of stock forecast amount" versus "total forecast amount".

When user select a row in this matrix, In a second matrix I want to show only the lower values then the selection in first matrix.

I created the first matrix but for second one I tried to use "Selectedvalue" function but it only works with columns not measures, so I stucked.

here is a sample file.

regards
