How can I Restrict Custom Date field value on subtask based on Parent issue?

Inayat Nahvi

Hi,

I have a custom date field called "Completion Date" on both standard issues and subtasks.  I do not want "Completion Date" on a subtask to be later that the "Completion Date" on it's parent issue.  How can I enforce this?  This should apply on when creating or editing the field.

For example, if IssueA Completion Date = 1-1-2021, then Completion Date on SubtaskA <= 1-1-2021.

Has anyone does this with Scriptrunner? Thanks.

Create a behaviour configuration linked to your project and sub-task issue type.

Then add a server-side script on the Completion Date field.

import com.atlassian.jira.component.ComponentAccessor

def dateFormat = 'dd-MMM-yyy'
def dateFld = getFieldById(fieldChanged)
def dateValue = dateFld.value as Date
dateFld.clearError()
def parentIssueFld = getFieldById('parentIssueId')
if(parentIssueFld && parentIssueFld.value && dateValue){
   def parentIssue = ComponentAccessor.issueManager.getIssueObject(parentIssueFld.value as Long)
   def cf = ComponentAccessor.customFieldManager.getCustomFieldObject(dateFld.fieldId)
   def parentDate = parentIssue.getCustomFieldValue(cf) as Date
   if(parentDate && parentDate < dateValue){
      dateFld.setError("Subtask Date (${dateValue.format(dateFormat)}) cannot be after the date of parent issue (${parentDate.format(dateFormat)})")
   } 
}
