  The SAP error message /SCMB/ORDER164 indicates that there is a missing unit of measure (UoM) for a specific order item in the Supply Chain Management (SCM) module. This error typically arises when the system expects a unit of measure to be defined for an order item, but it is not provided or is incorrectly configured.
  Cause:
  
  Missing UoM in Master Data: The material master data for the item may not have a defined unit of measure.
  Incorrect Configuration: The configuration settings for the material or order type may not be set up correctly, leading to the absence of a UoM.
  Data Entry Error: During the order creation process, the user may have omitted the unit of measure or entered it incorrectly.
  Integration Issues: If the order is being created through an interface or integration with another system, there may be issues with data transfer that result in missing UoM.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03) and verify that the unit of measure is correctly defined for the relevant material.

  Correct Data Entry:
  
  If the order was created manually, review the order details to ensure that the unit of measure is specified for each item. If it is missing, add the appropriate unit of measure.
