Lot Based Calculation of Processing Time.

Hello –

In one of the request from the user, he is asking for lot base production routing. For example: Discrete manufacturing -> routing -> operation no ‘190’ -> operation detail settings -> Machine time: 600 Min, set up and labour is 0 -> Base Qty: 1000. So with that calculation, if I have production order of say 4500 Qty, system will calculate total processing time as (600/100) * 4500 = 2700 Min.

While the fact is machine (Furnace) can only take 1000 pieces at a time. So ideally production will be in 4 batches (i.e. 4 batch of 1000 PCs and last batch of 500 PCs) and total processing time will be 600*5 = 3000 Min. And this difference of SAP set up and shop floor reality causes scheduling and cost variance. This logic requirement is only for few operations within routing. For all other remaining operations, logic described above is perfectly fine since they are not restricted work center (furnace).

Any suggestions to map this situation?
