Hi @shital chande ,

You should be familiar to scripting. There are lots of examples in Vendor website and community, please check this link. After finalizing your code, go to

  • Workflow -> Related transition -> Post-function -> Script Runner post-function -> custom script than paste it.
    *Btw, it is better to add as a ".groovy" file to JIRA_HOME/scripts directory and choose this file within Jira. 

Following code may guide you create sub-task. You can convert according your needs.

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.bc.issue.IssueService;
import com.atlassian.jira.user.ApplicationUser;
import com.atlassian.jira.issue.IssueInputParameters

try {

Issue issue = ComponentAccessor.getIssueManager().getIssueObject(issue.key);
IssueService issueService = ComponentAccessor.getIssueService();
ApplicationUser loggedInUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

IssueInputParameters issueInputParameters = issueService.newIssueInputParameters();

IssueService.CreateValidationResult createValidationResult = issueService.validateSubTaskCreate(loggedInUser, issue.getId(), issueInputParameters);

if (createValidationResult.isValid()) {
IssueService.IssueResult createResult = issueService.create(loggedInUser, createValidationResult);
if (createResult.isValid()) {
log.debug("Subtask successfully created : " +createResult.getIssue().getKey());
subtaskManager.createSubTaskIssueLink(issue, createResult.getIssue(), adminUser)
} else {
log.error("createResult is not valid.");
} else {
log.error("createValidationResult is not valid.");

} catch (Exception e) {

There are a few scripts in the library you might want to have a look at (as in "copy them") - see
