How to remove the filter from a measure

Hi,

I am trying to analyse a data set, below is the sample data

is it possible to get the count of a particular item ( slicer) and the total count of all the items for the order #?

What I am trying is to do is to add "Item" as slicer and I need to get the Count of selected item and the Total count of all the items in an Order #

for example if I add "Wire" in the slider the table should display the Count of selected Item as "1" and I need a measure to display the total count as "5" for the Order # as below

How do I create a measure to exclude the filter and show the Total count of all the items of an Order #

Kindly help to resolve this,

Regards,

Shyam.
