Hello....
I have to sum groups of twelve (12) numbers from a table with 10.000 itens, like this: 1 to 12, 2 to 13, 3 to 14...
I already tried using index numbers, with limits, with group, with where... but i can´t get this... i´m tryng to do this on SAS, but i can use SQL..
Any help is appreciated...
Thanks inadvance.
