Calculate number of days item in stock

[Anonymous]

I have a data set where each stock id number for each day it is in stock, is a row.  From this I have already created measures for Min and Max in stock dates.  Now I need to find the duration in stock for each stock id number.  How can I subtract the Min stock date from the Max stock date for each ID number?

@Anonymous , Try like

averageX(summarize(Table, Table[Stick ID], "_1", min([Min Stock Date]), "_2", max([MaxStock Date])), datediff([_1],[_2],Day))

Or use Sumx

@Anonymous - ([Max] - [Min]) * 1. = # Days

Greg, will that maintain the Stock ID relationship?

@Anonymous - If you put the Stock ID in a table visualization along with that measure, yes. I am making a ton of assumptions though.
