Hi,
In the following code, I would like to get the sum(item.qty) only for a particular item_code

total_qty = sum((item.qty for item in self.get(“items”)))

How do I do that?

thanks
Krithi

@krithi_ramani where? Client-side or Backend? JavaScript or Python sample?

3 
total_qty = sum([item.qty for item in self.get("items") if item.item_code = 'x'])

Shouldn’t it will run in backend? Just in curiosity, how can i do this in client-side? I am looking for just a simple demonstration, nothing else.

@ni8mr

var sum = 0;
cur_frm.doc.items.forEach(function(item){
    sum += item.item_code === 'x' ? item.qty : 0;
});
