I have maintained the PPC calender and attached that to WB lot size. I have only maintained the lot sizing procedure as P, indicator-K (PPC calender),scheduling=1 (period start=delivery date). I have maintained the Matarial master and ran the MRP. It is throwing Dep req based on the Planned order dates. Up to this it is fine. But as I maintained the PPC calender (wednes day is OFF). System is giving the depreq for all the days without considering the periods and PPC calender that is maintained. Another issue is, I want to summarize these depreq in to single procurement element. How to achieve these?
