Calculated field for date using fixed days

Dav1d J0nes

I have both JMCF and Scriptrunner so I could go either way with a solution here, I have tried some of the solutions provided in other community articles but no luck getting it to click yet. 

So I have field called "Date of Receipt"

I want to be able to create a due date based on that date + 30 days. So when the user creates the issue they will enter the date of receipt in a custom date field, i want it to display in separate custom field called Issue Due Date the date in the date of receipt field plus 30 days.

You can use script runner- add new post function > custom script, and add this code:

import java.sql.Timestamp;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.event.type.EventDispatchOption

def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser();
def customFieldManager = ComponentAccessor.getCustomFieldManager();
def issueManager = ComponentAccessor.getIssueManager()

def dateCustomField = issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(10504 as long))

if(dateCustomField != null){
 //if you want to set the system field Due Date
 issue.setDueDate( (Timestamp) dateCustomField + 30);

 //if you want to set a different custom field of type Date Picker 
 def customFieldToSet = customFieldManager.getCustomFieldObject(10500 as long)
 issue.setCustomFieldValue(customFieldToSet, (Timestamp) dateCustomField + 30);

 issueManager.updateIssue(currentUser, issue, EventDispatchOption.ISSUE_UPDATED, true)
}
