LOAD Customer, Avg(Sales) as MyAverageSalesByCustomer Resident Temp Group By Customer;

 

Customer MyAverageSalesByCustomer

Astrida 48.916667

Betacab 44.916667

Canutility 56.916667

Divadip 63.083333

This can be checked in the sheet by creating a table including the measure:
Sum(Sales)/12

Given that the Temp table is loaded as in the previous example:

LOAD Customer,Avg(DISTINCT Sales) as MyAvgSalesDistinct Resident Temp Group By Customer;

Customer MyAverageSalesByCustomer

Astrida 43.1

Betacab 43.909091

Canutility 55.909091

Divadip 61

Only the distinct values are counted.
