1. Material 'A' is part of different Sub Assemblies (SA-1 & SA-2).
2. After MRP run a requirement was generated for material 'A' (referencing SA-1) & this Purchase Requistion was converted to PO.
3. Subsequently when in the PO created for material-A, when i click on pegged requirement, it is now referencing SA-2
4. I am not able to understand how the PO has changed to reference to SA-2, while it should have referenced SA-1
5. In the MRP list i see another Purchase requisition has been created for material 'A' for SA-1.
