How to exclude certain part from MRP run

How do i excludes certain part from MRP process. i understand i can filter using part class, product group, sites, and parts. However, key in one by one in the Process MRP filtering is tedious.

anyway i can set in the part master, something like a check box to exclude the part from MRP process?

You can set this in the Part Master - Site Tab.
There is a checkbox: Process MRP
There is also one for PO Suggestions

Thanks, Michael. you resolved my problem.
