only function with set expression for dimension

[coloful_architect]

Hi community,

I have a table with business name, units, manufacturers. each business name could have multiple manufacturers.

I want to have a plan table with the field of business name to only show manufacturers count larger than 1 and its units% less than 60%. tried this at dimension of business name. but does not work out. 

any idea?

=aggr(only({<[Business Name]={"=count(distinct Manufacturer) > 1"},

max(aggr(sum([Pack Units]),[Business Name],Manufacturer))

/
sum([Pack Units])={'<60%'}>

} [Business Name]),[Business Name])
