[Yogesh Mude]

We have one multi select checkbox custom field called Impacted Application here suppose  I have selected 3 values and these three values should be carried and added to another issue with this custom field name.

for this,  we have written some code as below

{code}

import com.atlassian.jira.bc.issue.IssueService;
import com.atlassian.jira.bc.issue.IssueService.CreateValidationResult;
import com.atlassian.jira.bc.issue.IssueService.IssueResult;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.config.SubTaskManager;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.IssueInputParameters;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.user.ApplicationUser;
import com.atlassian.jira.issue.link.IssueLinkType;
import com.atlassian.jira.issue.link.IssueLinkTypeManager;

Issue parentIssue = issue;
ApplicationUser user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser();
IssueService issueService = ComponentAccessor.getIssueService();
CustomField brdTitle = ComponentAccessor.getCustomFieldManager().getCustomFieldObject(new Long(10249));
String brdTitleValue = parentIssue.getCustomFieldValue(brdTitle);

CustomField impactedApplication = ComponentAccessor.getCustomFieldManager().getCustomFieldObject(new Long(10242));
String impactedApplicationValue = parentIssue.getCustomFieldValue(impactedApplication);

IssueInputParameters issueInputParameters = issueService.newIssueInputParameters();
issueInputParameters.setIssueTypeId("10000");
issueInputParameters.setProjectId(parentIssue.getProjectId());
issueInputParameters.setAssigneeId(parentIssue.getAssigneeId());
issueInputParameters.setReporterId(parentIssue.getReporterId());
//issueInputParameters.setDescription(parentIssue.getDescription());
issueInputParameters.setSummary(parentIssue.getSummary());
issueInputParameters.addCustomFieldValue(new Long(10002), "Test");
issueInputParameters.addCustomFieldValue(new Long(10508), brdTitleValue);

if(impactedApplicationValue!=null)
{
Options options = ComponentAccessor.getOptionsManager().getOptions(impactedApplication.getConfigurationSchemes().listIterator().next().getOneAndOnlyConfig());
def optionToSelect = options.find { it.value == "PPM" };
issueInputParameters.addCustomFieldValue(impactedApplication.getId(), optionToSelect.getOptionId().toString());
}

CreateValidationResult createValidationResult = issueService.validateCreate(user, issueInputParameters);

if (createValidationResult.isValid())
{
IssueResult createResult = issueService.create(user, createValidationResult);
if (createResult.isValid())
{
Issue subTask = createResult.getIssue();
IssueLinkTypeManager issueLinkTypeManager = (IssueLinkTypeManager)ComponentAccessor.getComponent(IssueLinkTypeManager.class);
IssueLinkType linkType = issueLinkTypeManager.getIssueLinkType(new Long(10303));
ComponentAccessor.getIssueLinkManager().createIssueLink(subTask.getId(),parentIssue.getId(), linkType.getId(), null, user);
}
else
{
// System.out.println("Invalid createResult");
}
}

{code}
