PP _PS Integration

Hi experts,

We are implementing for a engineering construction company, So I want to know the Integration of PS and PP. Here the Bussiness is very dynamic, frequently switching over to one type of gate to another. How to create a Bom and Workcenter for this?

In penstock erection, Workcenter is moving one place to another place. How can I map in SAP?
