Hi folks, I am doing an export and need to compute some summary data. This is basically a flat file and the significant fields are account string,cost If the account strings match I want to roll those lines up and sum the cost.
below is an example
A100,1000 B100,2000 C100,3000 A100,4000 B100,2000
my output should be A100,5000 B100,4000 C100,3000
any ideas?
There are a lot of manners to do that…
Not the efficient way, but in full flow code:
(assuming you have a document list with 2 string account & cost)
But you can also create a java service with a Map (TreeMap ?). It’s just a question of algorithm.
Thanks, I didn’t think about a sorting routine.
