Each assigned target is valid for an unlimited period from its time stamp. The validity can be limited by further targets in the future, but cannot be deleted section by section based with reference to a time period. Lower/upper control limits are the exception. Therefore, only the complete target history can be deleted.
Prerequisites
The new target values apply from the selected time stamp.
The Delete history? dialog opens.
The target value history of the type groups or KPI elements is deleted.
The target history is deleted completely and permanently. This operation cannot be undone.
