Sum of repeated values

Can someone please advise how to add all "pv_estimate" values in the incoming message together and send the sum to the output? Thanks

I am guessing that the objects you have shown are elements of a payload array, as your image leaves alot of info out.

Feed the payload into a change node
set msg.payload
to JSONata J: $sum($$.payload.pv_estimate)

If that fails please present an input object that is copyable.

I am still guessing that that info is in payload
$sum($$.payload[0].estimated_actuals.pv_estimate)

Please show image of debug showing full msg object, if this did not work.

Yes, but "estimated" array is four times, and each have 48 "pv_estimate" records.
$sum($$.payload[0].estimated_actuals.pv_estimate) works for only first

I saw your image as one array. Then your copyable object was so large i did not see the 4 arrays. Maybe next time cut it down to 3 objects per array element for testing.

Anyway

For 4 separate array results $$.payload.$sum($.estimated_actuals.pv_estimate)

For the total of all $sum($$.payload[*].estimated_actuals.pv_estimate)

1 Like

It works! Thank you for saving lot of my time.
