Step 4: Exploring Additional Functionality

SAP transaction MC91 offers various additional functionalities to enhance your forecast consumption management. Here are some notable features you can leverage:

  • Display Consumption Values: Use MC91 to display existing consumption values for materials by entering the material code, plant, MRP controller, and period indicator. This allows you to review and analyze the consumption trends over time.
  • Change Consumption Values: MC91 also enables you to modify existing consumption values. You can adjust the values based on the updated usage data or forecasting information. Simply enter the material code, plant, MRP controller, and period indicator, and make the necessary changes.
  • Copy Consumption Values: If you need to maintain consumption values for multiple materials or plants, MC91 allows you to copy the values from an existing material/plant combination to another. This feature saves time and effort in data entry.
  • Mass Maintenance: MC91 supports mass maintenance of consumption values, allowing you to update multiple materials or plants simultaneously. You can use the “Mass Change” option to make bulk changes to consumption values based on specific criteria.
