Jira Cloud Automaton - Custom field text to custom field drop down?

[Mike Singleton]

Hello,

I have a custom field (single line) that I am populating with the possible values
Small (weeks),
Medium (months),
Large (quarter)
XLarge (quarters),
XXLarge (year)

which once filled out (on edit) I want to match with another custom field that has these exact same values and via automation have the same value selected and saved.

Hi @Mike Singleton, here is a similar post where you can get some insights into implementing it using Automation for Jira. Have a look, and let us know if you can apply it to your use case.

I don't think I need to clear the field "T-Shirt Size Estimate" just copy the value from the other field "Build". What would I modify in the statement below to do this?

{
"update" : {
"T-Shirt Size Estimate" : [{"set": []}]
}
}

I tried with no luck

 {
"fields": {
"customfield_11305": "{{issue.customfield_11304}}"
}
}

Fields is a shortcut for calling update with the set operation. See more details here. I'd suggest breaking your implementation into smaller steps so you can resolve one piece at a time. For a single-select custom field, you should be using the following: 

"customfield_11449" : { "value": "option3" } 
or 
"customfield_11449" : { "id": 10112 } 

Once you make that work, you can use a smart value to set the option. See Find the smart value for your field for more details.

so it would be something like

IF the value in the source field (11305) is "Small (Value 10491)" then update the target  (11304) with that value?

 {
"fields": {

"customfield_11304" : { "id": "10491" }

}
}
