Combining multi-choice fields from 2 lists

(0) ShareShare
ReportReport
Posted on by 2
I have a Flow that looks up 2 lists and gets the 2 multi-choice fields in a Select action and I have them displaying in Arrays like this:
Select Action 1:
[
  {
    "Name": "Test1"
  },
  {
    "Name": " Test2"
  },
  {
    "Name": " Test3"
  }
]
Select Action 2 (This one gets put in a ""For Each" control for some reason):
[
  {
    "Name": "Test4"
  }
]
How can I combine these into one so that I can use it to Update item in a SharePoint list?

    You can use the union function to merge these two arrays. You can also refine the data by selecting the Switch to Map mode in the Select action to select just the values:

     
     
     
     
     
     
     
     
     
    union(body('Select'),body('Select_2'))

    Hi EKarim,
     
    I had to switch "Name" to "Id", so my Select actions look like this:
     
     
    Compose looks like this:
     
    I think I need my Compose to look like this:
    [
      {
        "Id": "90"
      },
      {
        "Id": " 1"
      },
      {
        "Id": " 3"
      },
      {
        "Id": " 2"
      }
    ]
     
    So that I can use it to update a Multi-Choice field in a SharePoint list. 
     
    Is this possible to make it format that way?
