Filter array to get the maximum value among a set of numbers

[fdurante]

Hi everyone,

this might be a newbie question. I'm currently trying to build a flow which filters an array to get the maximum value among a set of numbers.

The body (result of a series of connectors and operations I did before in the flow) I have to filter is:

[
  {
    "year": 2019,
    "objectId": "39aed1d3-22e7-41f4-80a7-98180afd76f9"
  },
  {
    "year": 2018,
    "objectId": "99b17061-b967-4337-8c38-60842780f1b6"
  },
  {
    "year": 2017,
    "objectId": "5b280760-6fd2-404f-93c1-6b5af5b390e8"
  },
  {
    "year": 2016,
    "objectId": "e40be3bc-a632-4c9d-b458-1e6da1aba740"
  }
]

I need to filter the array in order to have only the element with the maximum value of year (in this case, 2019) and its objectId in it. I've tried my best by initializing variables, filtering year by "value equal to max(item()?['year'])" and many other things, but nothing seems to work correctly...

How can I do it?

Thank you very much,

FD

@fdurante:

Can you tell me where your data is coming from?  SharePoint?  I ask becaus it may be easier to filter the data when it is retrieved.

They are a set of dataflows coming from Power BI, but I have already made some changes to the original fields (which were for example some strings, and among them some "string + year" which were then extracted and modified).

By the way, I've followed the solution I found here and it worked fine for me, so the issue is now resolved.

Thank you,
