[libreoffice-users] question with selective sums

Hello,

I received today a question about a spreadsheet I can't answer
immediately. Though I'm convinced this must be possible.

We have a sheet with
A : stock location
B : item n°
C : quantity

The user wants now the sum per item, preferable in another sheet with
the same layout, or in a automatically generated accumulated line.

In the help I can see something about array formulas, which seems
interesting, but I want an automatic break per item no.

Example

|--A---|----B----|----C----|
|WH1| Item1 |    10   |
|WH1| Item1 |    10   |
|WH1| Item1 |    10   |
|WH1| Item1 |    10   |
|WH1| Item1 |    10   |


Met vriendelijke groeten, Salutations distinguées, Kind Regards,
