I'm new to QS and I'm trying to grasp its syntax and scripting features in order to set up a reporting and dashboard view for my company.
I should set an expression for a KPI box that'd allow me to calculate the distinct number of unique "# ID booking" when/if the associated VAR. NS is >0, in order to analyze how many bookings out of total generate a VAR. Net Sale.
I tried to sort it out myself but it either doesn't work or it returns me an invalid number.
