I created a field named Select Parent which is an issue select picker. I want to have the parents of that specific issue in that field to be able to select one them. 

How should i do it ? With a groovy script or with a JQL request ? 

Please can you provide both solution. 
Here's the field :

Here's the configuration of the field :

Hi @Willyam Mudingayi Malumba Welcome to the Atlassian Community.

I believe your post isn't getting traction because of an inconsistency in your question.

• A Jira work item can only have one parent.
  The key of that parent is stored in the parent link field. 

Please rephrase your question with the above in mind, so we can look at it differently.

Kind regards,

Dick

Hi Dick, 

In our configuration a Jira issue can have multiple parent and they are linked by a type "ALM_LINK" so if you do the linkedIssue(key, "ALM_LINK", 1) you find all the parents of the key. 

My question is how can I do the same with a groovy script. I want to be able to find all the issue related (parents) to my current issue based on the linked type. 

Thanks!
