Function in alteryx - summarize varios rows into one

[Cesc]

Hello Alteryx forum,

I was trying to create a summary of accounts per document number. So what I needed to do is the following:

1. I have this dataset. I would like to add another row that summarizes the field 3DIG per Nº asiento periodo 2. So, the first three lines of the new field would be:

N asiento    NEW FIELD

15                430+438

20                432+574

21                432+555+665

22                430+432                

Would really appreciate your help.

Thanks
