Hi Sameer,
Your design of routing is not proper. What I understood from your question is for cutting operation you will be using any one of the five cutting machines (which are having same capacity). If my understanding is correct you can explore following options.
1. Using planning resource/work center option...
2. Actual work center during confirmation
Change of resource in time ticket process order confirmation
3. Work center classification
In the routing you can put only one operation for cutting (instead of maintaining five times) and assign any one of the five work centers to this operation or a planning work center (option1).
Hope this helps
Thanks
Kumar
