BOM of material A is made inactive at header level on 06.03.2009. All the components in the BOM are assigned to MRP area. Now we have one planned order (i.e. stock order - 12.03.2009) for material A. The procurement proposals for components are not coming at plant level but they are coming on MRP area level. As BOM is inactive at plant level then the components should not be planned via MRP at plant level but as there is only one BOM then how procurement proposals are created even at MRP area level? What should be the settings to stop generation of procurement proposals at MRP area also? It is possible to mark deletion indicator at MRP area in MRP1 view.
