table to show only data with positive sales within 6 months

[coloful_architect]

hello community,

I have table with business name( customer) and units 

wanna show only active customers with sales above 0 within 6 months

I tried this , as long as 6 month sum larger than 0, show its all sales units.

=if(sum({<DateFieldMonthYear={"Jan-21","Feb-21","Mar-21","Apr-21","May-21","Jun-21"}>}[Pack Units])>0,
sum([Pack Units]))

but it returns me very funky result.

I decompose the formula to see if something wrong with that major set expression filtered with month, it looks good

Need your help thanks.

much appreciated If you could list two ways for dimension and measurement

Enable the suppress zero/null option on your table, and then use whatever formula you normally would to get the sales contained within a RangeMax() function, e.g.

RangeMax(0,Sum(Sales))

This will result in all negative / null values being set to 0, and thus being suppressed.

now everything becomes 0....see my formula
=rangemax(0,if(Sum({<DateFieldMonthYear={"Jan-21","Feb-21","Mar-21","Apr-21","May-21","Jun-21"}>}[Pack Units])>0,
sum([Pack Units])))

would that be something to do with ">0" ....? so confused .

so  I then realize I accidentally set up that limitation to a %  value which return all those funky result.

To appreciate your support and intention to help me, I would love to give you the solution.

For whoever read this post, just FYI. the formula list below actually works !

if(sum({<DateFieldMonthYear={"Jan-21","Feb-21","Mar-21","Apr-21","May-21","Jun-21"}>}[Pack Units])>0,
sum([Pack Units]))
