Filter out specific category in field parameter

Hi Team,

I have created a field parameter from 2 dimesion table (Global dimension Table & Local dimension Table) keeping 4 columns (category,Sub category, Brand, Sub Brand). Both Dim tables are connected to Fact_Product table on product_code column.

from Global dimension Table I want all category but from Local dimension Table I want only 3 categories to be displayed in matrix visual.
