Re-run of MRP after a Design Change


Dear Sir,

We are facing a Problem in a scenario as detailed below :

Say there is an Assembly AS-1 having 2 sub-assemblies under it i.e AS-1-1 and AS-1-2 . The sub-assembiles have ROH under them i.e AS-1-1 --> RM-1 and AS-1-2 --> RM-2.

We had run the MRP MD02 for AS-1 . The requirement got generated as per the BOM .

Subsequently , we generated the Production Order from Planned Order for the components i.e AS-1 , AS-1-1, AS-1-2 .

Later on there was a change from the Customer side , so to accomodate the change Design got changed for the Assembly AS-1 . Now , it will have another additional sub-assemby also i.e AS-1-3 . The new additional sub-assembly has ROH under it as AS-1-3 --> RM-3 .

We run the MRP again MD02 for AS-1 (Parameter given in MD02 are NETCH / 3 / 3 / 1 / 2 / 1 ) . We find that in MD04 no requirement is appearing for the sub-assembly AS-1-3 .

We request you to kindly guide us , as what procedure we should follow so that additional new requirement of AS-1-3 is generated after the re-run of MRP .
