Hi Experts,
Material A was below its reorder point. MRP created a purchase req-ABC and latter converted to Purchase order-123xxx. Then I can see in MD04 that the Purchase Order-123xxx has an exception message 20 (cancel process). When the MRP background job run another purchase req was created because the stock is below the reorder point.
I am wondering why it creates another purchase req-DEF, MRP should still recognize the Purchase Order 123xxx. Therefore should not generates new PR.
How exception message generates? do you think it affects the MRP run?
