I've created a finished material with 2 raw materials. BOM was also created. But didn't create work center & routing. I select the application of BOM as universal. Procurement type as both procurements.
1.Then I've created PIR for the finished material. It was raised, but didn't raise the dependant requirements ( i.e, Planned or Purch. orders were not created for Raw materials based on the PIR.
For planned order creation routing is not necessarry and you have the valid MRP settings in the material master. Check the MRPtype maintained for the lower level material and check the stocks also.
