No Purchase Requisition Generated after MRP Run MD02

Hi All,

After runing MRP Run MD02 for finish product with MRP Control parameters for create purchase requisition as 1 (Create Purchase Requisitions) . System is not generating any purchase requisitions for raw materials required for assembly.

If we select 3 create planned order system is able to generate planned orders for raw materials required for assembly.

Plz guide why am not able to generate purchase requisition directly.

Regards,

Sipra
