Issue links

Add a Relates to issue link and link it to the current issue

Additional options

Add a second Create issue post function

Add another Create issue post function after the previous post function in the same workflow transition.

Issues to be created

Mode

Choose Multiple issues

Expression

Enter the following parser expression with parsing mode set to Issue list

issuesUnderEpic()

Issue type

Choose Parser expression (standard issue type) and use the following expression:

^%{issue.issueType}

Summary

^%{issue.summary}

Description

Epic link

Choose Field in current issue and Ephemeral String 3

Template issue

Choose Parsed text (advanced mode) and write the following expression:

Copy remaining fields

Select From seed issue and All remaining fields

Additional options

Tick Store issue keys

Add a third Create issue post function

Add another Create issue post function after the previous post function in the same workflow transition.

Issues to be created

Mode

Choose Multiple issues

Expression

Enter the following parser expression with parsing mode set to Text list

toStringList(toString(textOnStringList(toStringList(replaceFirst(%{00063}, "^([^,]+,\\s)", ""), ","), toString(textOnStringList(fieldValue(%{issue.cfTemplateIssue}, issueKeysToIssueList(^0%)), findModify(toString(subtasks(^1%)), "[^, ]+",^0% + ":" + ^2%))))), ",")

Replace the field code %{issue.cfTemplateIssue} with the field code of the Template Issue field in your instance.

Issue type

Choose Selected issue type and select Sub-task

Parent issue

Select Set parent manually (parser expression) and use the following expression.

replaceFirst(^%, ":.*$", "")

Summary

Enter the following expression with parsing mode set to Advanced text

toString(fieldValue(%{00000}, issueKeysToIssueList(replaceFirst(^%, "^.*:", ""))))

Description

Enter the following expression with parsing mode set to Advanced text

toString(fieldValue(%{00001}, issueKeysToIssueList(replaceFirst(^%, "^.*:", ""))))

Additional options

Update the following fields

Assignee

Choose Parsed text (advanced mode) and write the following expression:

toString(fieldValue(%{00003}, issueKeysToIssueList(replaceFirst(^%, "^.*:", ""))))

Due date

Choose Parsed text (advanced mode) and write the following expression:

first(fieldValue({00012}, issueKeysToIssueList(replaceFirst(^%, "^.*:", ""))))

In this case we cannot use the Inherit field values parameter in the post-function for the creation of sub-tasks. Instead, we must use a different expression for each field that we want to copy into sub-task's clones. The expressions to be used are the following ones.

For Number and Date-Time fields:

first(fieldValue({issue.cfTemplateIssue}, issueKeysToIssueList(replaceFirst(^%, "^.*:", ""))))

For the rest of the fields:

toString(fieldValue(%{issue.cfTemplateIssue}, issueKeysToIssueList(replaceFirst(^%, "^.*:", ""))))

Replace the field code %{issue.cfTemplateIssue} with the field code of the Template Issue field in your instance.
