How to group multiple orders lists into one 'picking list' with items summary

[Igor_Silva]

Hello everybody!
I'm developing an app to receive three orders weekly. I have 90% of the app ready, but I am not managing to generate a report containing a picking list that sums products of all order lists together. Any idea how to achieve this?

You want to generate some "Grouping" inside the report without needing an extra table?
You need to nest start: expressions.

Almost there! I need something like this:

ORDER  1:

QUANTITY	PRODUCT
1	PROD-A
4	PROD-B
2	PROD-C

ORDER 2:

QUANTITY	PRODUCT
3	PROD-A
5	PROD-B
10	PROD-C

I need to make this list:

PICKING LIST: (order 1 + order 2)

QUANTITY	PRODUCT
4	PROD-A
9	PROD-B
12	PROD-C

You can use as much groups as you want
