Can report include total number of SKUs ordered?

hello

select format Csv (or xls)
open section “Set up fields to export”
unselect all ( checkbox above fields)
check Products only
check export “as rows”
click on button “Set up fields to export”
check 2 fields “SKU” , “Qty”

so you will get file with 2 columns
5 SKU01
10 SKU01
15 SKU02
2 SKU02

Use Pivot or Grouping to get results
