Can you please help me with script of the below use-case –  

For a sub-story which is linked to a story.

Hi Swapnil,

I understand your use-case and I think I have a script that almost accomplishes this, but could you clarify?

Do you want the sum of ALL issues in the project that have an issue type of "Sub-story", regardless if they are connected to the same Story?

  • Example: Calculate the sum of 'Technical Points' of all issues that have an issue-type of "Sub-story" in the entire project.


Do you want the sum of all connected "Sub-story" issues for each Story?

  • Example: A Story has 5 sub-stories. Calculate the sum of the 'Technical Points' of the 5 sub-story issues and display on the Story.

Hi Joshua,


Thank you for looking into this.

I would require the second example - 

"Do you want the sum of all connected "Sub-story" issues for each Story?

  • Example: A Story has 5 sub-stories. Calculate the sum of the 'Technical Points' of the 5 sub-story issues and display on the Story."


Thanks again for your help.

Best Regards,

Hi Swapnil,

I created the following script to be used in a scripted field. It gets all of the links from the Story and checks to see if the are of type "Sub-story". If there are "Sub-story" linked issues, it will get the custom field value from "Technical Points" on each issue. It will return the sum of all of the Sub-story issues linked to the Story.

import com.atlassian.jira.component.ComponentAccessor

if (issue.getIssueType().name == "Story") { // only calculate this for Story Issue Types
def issueLinkManager = ComponentAccessor.getIssueLinkManager()
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def pointSum = 0
issueLinkManager.getOutwardLinks( {issueLink -> // go through all issues linked off of the Story
def linkedIssue = issueLink.getDestinationObject()
if (linkedIssue.getIssueType().name == "Sub-story") {
def technicalPointsField = customFieldManager.getCustomFieldObjectByName("Technical Points")
pointSum += linkedIssue.getCustomFieldValue(technicalPointsField)?:0
return pointSum

You should also make sure that the Template for the Scripted Field is set to "Number Field" and that the Searcher is set to "Number Searcher".

Hi Joshua,


The query is giving me the error.

It says "The variable issue is not declared"


Please help

Thank you,

Hi Swapnill.

That is an inline error, not a compilation error. The script could be working at compilation time. Could you save the script regardless and try to see if the script works?



Hi Daniel,


It is not working.


Thank you,

Swapnil Tiwari

Hi Swapnil,

You are using this code inside of a scripted field, correct? Which version of ScriptRunner are you using?
