Splitting Capacity Requirements in Production Orders 
Use
In the production order on the operation detail screen Splitting you can split the total requirements of the operation into partial requirements (so-called splits). Two types of split are possible: a quantity split or a standard value split.
You can distribute the operation quantity or standard values over the individual capacities or people created for the capacity category and specify when the individual splits are to start.
The operation quantity for an operation is 100 pieces. The operation is processed at the work center XYZ. You specify that 40 pieces are to be processed on machine 001 and 60 pieces on machine 002. This is a quantity split. Machine 001 and machine 002 must be allocated as individual capacities to the machine capacity in the work center XYZ.
If you have an operation quantity of 100 pieces and employee A and employee B process the same 100 pieces on one machine one after the other then the split quantity for employee A and employee B is 100 pieces each. However, since each employee only requires half of the standard time to process each piece, the standard values must be reduced accordingly. This is a quantity split. Employee A and employee B must be assigned as people to the labor capacity in work center XYZ or to the work center XYZ.
You can display a ranking list for the capacities to which people are allocated using the function key Ranking list . The system displays the suitability of people, who are assigned to the work center and the capacity category, in the ranking list. This ranking list depends on the overall requirements profile, which is made up of the work center, capacity and operation.
The allocation of partial requirements to individual capacities or people only constitutes dispatching if the indicator D (split dispatched) is set. If this is the case, the splits that have been created are given the status "dispatched" once the allocation has taken place and the production order saved. If you have not set the indicator then you can dispatch the splits on the planning tables.
