How to automate adding choices to multiple choice field based on smart value condition?

csenge.virag.kiss

Hey, 

I have an advanced form that I would like to use to trigger a change in a multiple choice field. This change should not impact existing choices in the field. 

 

So if condition is true the my multiple choice field has a new selection added to it. 

 

Any ideas how I can actually achieve this. It should be possible with simple condition & "Edit work item" action, but my field is always updated but all previous choices are updated too.

 

Is this even possible? I am working in Jira cloud and not JSM.

 

Thank you in advance for the help.

Hi @csenge.virag.kiss and welcome to Atlassian Community!

Please check Advanced field editing using JSON.

The reason your existing choices are being overwritten is because you’re using fields (set).
For multi-select fields you must use update with add / remove / set.

Here’s a short example showing all options for a multi-select custom field 
(customfield_12345):

Add (keeps existing values)

{
    "update": {
        "customfield_12345": [
            { "add": { "value": "New Option" } }
         ]
    }
}

Remove (removes only one value)

{
    "update": {
        "customfield_12345": [
            { "remove": { "value": "Old Option" } }
        ]
    }
}

Set (replaces everything)

{
    "update": {
        "customfield_12345": [
            { "set": [
                 { "value": "Option A" },
                 { "value": "Option B" }
            ]}
        ]
    }
}

Clear field completely

{
    "update": {
        "customfield_12345": [
            { "set": [] }
        ]
     }
}
