And, for every sale (in this example with id 1), I've to determined multiple dimensions for the "sales family" (depending on the sales detail). So, as a result, in this example for the sales with id 1 I'd have:
5 items sold (detail).
3 sales family: graduado, graduado, lentilla/PM
30 EUR for graduado family in the sale with id 1.
20 EUR for lentilla/pm family in the sale with id 1.
Then, is it possible to determine more than 1 dimension (graduado, lentilla/pm) for a grouping dimension (sale, id 1)?
