You can only change the base units of measure unter the following circumstances:

  • No stocks are available for the material.
  • There are no existing purchase requisitions, purchase orders, or scheduling agreements for the material.
  • At present, no purchase orders or purchase order items are being created or changed.

If requests for quotations, purchasing info records, or contracts are available for a material, the system emits a warning if you change the base unit of measure. If one of these objects is then changed into an order, you only need to specify in a dialog box the factor for converting the base unit of measure into the new base unit of measure. The purchasing info records are then, if necessary, updated.


  1. Call the material master record in the create mode.
    1. Overwrite the old base unit of measure with the new one in one of the user department screens.
    1. Save the change.


    The system checks whether the base unit of measure may be changed. If this is not the case, the corresponding warning appears. To display the reason for this, choose Display Errors.
