  The SAP error message:
  WG023 - Unit of measure missing. No search allowed. Order item & incorrect
  
  Cause:
  This error occurs when the system expects a unit of measure (UoM) for a particular order item but does not find it. The unit of measure is a mandatory field for order items in sales and distribution (SD) or production orders. The message indicates that the UoM is missing or incorrect for the specified order item, and because of this, the system cannot proceed with the search or processing.
  Common causes include:
  
  The unit of measure field is left blank or not maintained in the sales order or production order item.
  The unit of measure entered is not valid or not recognized in the system.
  The material master record for the material in the order item does not have a base unit of measure or relevant UoM maintained.
  Customizing or master data inconsistencies where the UoM is not properly defined or linked.
  
  
  Solution:
  
  
  Check and maintain the Unit of Measure:
  
  Go to the order item in the sales order or production order.
  Ensure that the unit of measure field is filled with a valid UoM.
  Use the standard UoM maintained in the material master (usually the base unit of measure).
  
  
  
  Verify Material Master Data:
  
  Check the material master (transaction MM03) for the material in question.
  Ensure that the base unit of measure is maintained correctly.
  Check if alternative units of measure are maintained if used.
  
  
  
  Check Customizing Settings:
  
  Verify the unit of measure settings in SPRO under:
  Logistics - General > Units of Measure > Check Units of Measure
  Ensure that the UoM used is active and valid.
  
  
  
  Correct the Order Item:
  
  If the order item was created with an incorrect or missing UoM, correct it manually.
  If the order is created via interface or batch input, check the input data for missing UoM.
  
  
  
  Recreate or Adjust the Order:
  
  If the order item cannot be corrected, consider deleting and recreating the item with the correct UoM.
