Hi Siva
There is not enough information to answer your question. Is this a MTO or MTS order? Which MRP type are you using? Did you note if the material was planned by MRP during these days? Can you please share a screenshot of MD04/MD05?
Maybe, the planning file was not marked when the sales order was created and the material was planned by a NEUPL MRP run later. If this is the case, we will never be able to prove, as there is not enough information on the system.
