• Planned order schedule -- quantity of material to be bought in everytime period • Changes to designed orders - modifications to previous designed orders • Secondary outputs: – Exception reports – Performance reviews – Organizing reports 21 years old

Secondary MRP Reports

• Planning information, for example , foretelling of inventory requirements over a period of time • Performance reports used to determine arrangement between real and designed usage and costs • Exception information used to point out serious mistakes, such as later or overdue orders
