SAP Note 27597 - Processing of several splits causes disappearance

Symptom:

If you select several scheduled splits on the planning table for individual capacities and perform the function "Deallocate", not all splits are displayed on the partial screen of the unscheduled splits. This also applies to other functions concerning splits.
