Pivot Table:delete zero values when using calculated objects

Hi, everybody!

In Pivot Table create calculated object. However at its application zero values of fields become visible. How not to display them, but to use calculated object?

In PT_object.xls in detail I drew - that turns out (the table at the left, excess values are filled in red) and that it is necessary to receive (the right table)

Thanks!

P.S. Sorry for my English, i used the Internet translator

Friends!
My question is so difficult?
Or it has no decision?
