Modify a custom gield based on a specific condition

[miguel.caba]

I want to conditionally modify a custom field in Jira. This modification should be triggered by a specific condition related to the 'Cause Field'. For example, when the 'Cause field' is set to "1", I want the ' Category field' to display only the options '1.1','1.2','1.3'.

I have attempted ussing this JSON script: 
{
"update": {
"customfield_11319" : [
    { 
   "set": "1.1,1.2,1.3"
  }
  ]
}
}

But I´m encountering the errpr 'specify a valid 'id' or 'name'. And I´m sure the 'id' of the customfield is correct. Could anyone provide guidance on the correct approach to achieve this? Any help would be greatly appreciated. 

Thank you!

Hi @miguel.caba 

Welcome to the community.

First of all, you would like to set "Category Field", right? (Because automation is not used to change the display values).

Please re-check this Advanced field editing using JSON doc, there are examples to set multi-level fields.

Sample:

Multi-select custom field

"customfield_11448" : [ { "value": "option1" }, { "value": "option2" } ] 
or 
"customfield_11448" : [ { "id": 10112 }, { "id": 10115 } ]

Thank you for your reply! 

For example, when the 'Cause field' is set to "1", I want the ' Category field' to display only the options '1.1','1.2','1.3' ('Category Field' has more options).

Is it possible to achieve this in Jira, maybe not using automation?

Thank you!
