3143395 - The resource scheduler allows users to drag and drop demands on non-working hours


  • You are trying to re-schedule a demand to a user and found it is possible to drag and drop the demand over non-working hours
  • The expectation is to either receive a warning message or for the system recalculate the allocation and subtract the non-working hours

Reproducing the Issue

  1. Go to the Resource Scheduler [Gantt chart]
  2. Select a demand from the list
  3. Drag and drop that in the timeline
  4. Now drag and drop the same demand over a timeline that intersects with a non-working hour(s)


  • For cases where a demand is rescheduled, the system is designed to allow the user to place the rescheduling based on user's discretion
  • Per the "Gantt Chart in Resource Scheduler" documentation, the system is designed to show the:
    • Non-working hours are indicated as blocked (grayed out) in the Gantt chart
    • In addition, the duration for any regular appointment is also shown as blocked in the Gantt chart
    • Sometimes assignments cannot be created due to certain reasons
    • In such scenarios, the system plans as per validity/availability
    • The remaining hours are sent back to the demand list
  • The following are also some examples of why assignments may not get created:
    • If non-working hours or all-day events exist at a stretch for more than the defined threshold value.
    • If a temporary team assignment ends.
    • If the employee validity expires.


  • The system is working as designed
  • It is the expected behavior to allow the users to reschedule a demand and not prevent drag and drop over non-working hours
  • The system is designed to leave the decision on the planner's judgment to either moved/extended the assignment to non-working hours
  • If you feel this behavior should be changed, then we invite you to submit an idea request via the SAP Customer Influence Program. Refer to KBA 2531650 for more details.
