Is group by allowed in precedingg load?
Or we have to group it in the main load and take the summary data into preceding load?
Hi, it should work,I tested with this script:
Sum(Ventas) as Ventas
Group By Articulo, Fecha;
LOAD * Inline
Articulo, Fecha, Ventas
A1 ,01/01/2017, 10
A1 ,01/01/2017, 80
A1 ,02/01/2017, 20
A2, 02/01/2017, 30
Be very careful. You will get all sorts of side-effects that you cannot immediately explain. And yes it may work on simple examples. But those are not necessarily what you need in your situation.
Better use simple things in a Preceding LOAD, and do the GROUP BY in a separate operation on an internal table.
