Dates are not rolling up from sub task to parent taskIssue Inconsistency in project and project task dates for multiple records. All Project Tasks are closed but the Actual end date is not populated in projectFor 2 project task Actual End Date is not present Steps to reproduce:---------------1)Consider any project task which has sub task.2) Close all the sub task except for one task.3) Change the state to Work in progress.4) Update the Actual end date prior to Actual start date and save it.5) It will throw the error " Actual end date cannot be earlier than actual start date " and the sub task will be not be updated. But its parent task state will be updated to Closed Complete.6) Since the tasks is still in work in progress and it's parent is closed, date will not be rolled up.So, Project got closed with Work in Progress task.OOB (out of box) BR (business rule) "Validate Work End before Work Start" did not abort the action but before the state got updated at Parent.CauseRecalculation business rule was skipped on the instance There are multiple root causes for the issue:- editing parent task which has sub tasks"PPM Unable to Recalculate Task : <<task_id>> change_of_planned_end_date_not_allowed". you can see this error in logs. Both actions result in same issue : dates not rolled upResolutionTry changing the order of OOB BR "Validate Work End before Work Start" from 10,000 to 100 so that validation happens before rolling up rather than after state rollup. After applying the fix, step 5 in the 'Steps to reproduce' is no longer reproducible hence step 6 will not occur
