You can use an aggregate expression in a SELECT statement. That way you can call an aggregate function from multiple rows on a results set:

@AbapCatalog.sqlViewName: 'SALES_ORDER_VW'
define view sales_order as
select from snwd_so
{ key buyer_guid,
   @Semantics.currencyCode
    currency_code,
   @Semantics.amount.currencyCode: 'currency_code'
    sum(gross_amount) as sum_gross_amount }
group by buyer_guid, currency_code

So in your view, you could do something like:

sum(name_of_field) as sum_of_field
