Changing the Base Unit of Measure 

Prerequisites

It is only possible to change the base unit of measure in the following cases:

  • If there are no stocks of the material in the system
  • If there are no purchase requisitions, purchase orders, or scheduling agreements for the material
  • If a purchase order or purchase order item is not being created or changed

If requests for quotations, purchasing info records, or contracts exist for a material, the system merely issues a warning when you change the base unit of measure. If one of these later becomes a purchase order, you simply have to specify the factor for converting the order unit to the new base unit of measure in a dialog box. The purchasing info record is then updated if necessary.

Procedure

  1. Access the material master record in Change mode.
  2. Overwrite the old base unit of measure with the new one on any departmental data screen.
  3. Save the change.
  4. Result

    The system checks whether the base unit of measure can be changed. If it cannot be changed, a message appears to this effect. Choose Display errors to display the reason.
