What is the expression behind Current Month %? 

[prrajendran]

this is the expression sunny

count (DISTINCT{<[ProductNum]={'>0'}>}Sales)
/
(count (DISTINCT{<[ProductNum]={'>0'}>}Sales) + count (DISTINCT{<[InvoiceNum]={'>0'}>}Sales))

[sunny_talwar · Accepted solution]

Try this

RangeAvg(Above(

count (DISTINCT{<[ProductNum]={'>0'}>}Sales)
/
(count (DISTINCT{<[ProductNum]={'>0'}>}Sales) + count (DISTINCT{<[InvoiceNum]={'>0'}>}Sales))

, 0, 6))
