**Scenario:**

1. Create a work package "Parent 1".
2. Add a start-date and a finish-date.
3. Begin of the deletion Switch to automatic scheduling mode.
4. End of the deletion Add a work child element Begin of the deletion without dates.End of the deletion

**Current behavior:**

* By adding a child work package the dates of the parent Begin of the insertionwork packageEnd of the insertion Begin of the deletion worpackageEnd of the deletion get Begin of the insertionset automatically and by that override the previously set dates.End of the insertion Begin of the deletion lost.End of the deletion
* The dates in the create form of the child work package is empty. Begin of the insertionIf the setting `work_package_startdate_is_adddate` is active, the start date is set to today.End of the insertion

* In the create form of the sub work package the parent's dates are pre-selected. Begin of the insertionIf only one of the dates exist, only one of the dates are set (e.g. only parent's finish date is set, then only the child's finish date is set.End of the insertion
