• What is the cause and solution for SAP error message WH058 - No ISO code defined for unit of measure & ?

  SAP Error Message:
  
  WH058 - No ISO code defined for unit of measure &
  
  Cause:
  This error occurs when the system tries to process or transfer data involving a unit of measure (UoM) that does not have an associated ISO code defined in the system. The ISO code is required for certain processes, especially in warehouse management, shipping, or integration scenarios where standardized unit codes are necessary.
  In SAP, each unit of measure can have an ISO code assigned in the system to ensure consistency and compliance with international standards. If this ISO code is missing for a particular UoM, the system cannot proceed and throws the WH058 error.
  
  Where it typically occurs:
  
  Warehouse Management (WM) transactions
  Integration with external systems (e.g., EDI, shipping interfaces)
  Material master data processing involving UoM
  Delivery processing or packing where ISO codes are mandatory
  
  
  Solution:
  
  
  Check the Unit of Measure:
  
  Identify the UoM causing the error (the message will show the UoM code in place of "&").
  
  
  
  Assign ISO Code to the Unit of Measure:
  
  Go to transaction CUNI (Units of Measure).
  Enter the UoM that caused the error.
  Assign the appropriate ISO code for that unit.
  
  ISO codes are standardized codes for units, e.g., "KG" for kilogram, "L" for liter, "M" for meter.
  
  
  Save the changes.
  
  
  
  Verify Material Master Data:
  
  Check if the material master uses the UoM without ISO code.
  If necessary, update the material master or related data to use a UoM with a valid ISO code.
  
  
  
  Reprocess the Transaction:
  
  After assigning the ISO code, retry the transaction or process that caused the error.
  
  
  
  
  Additional Information:
  
  Transaction CUNI is the central place to maintain units of measure and their ISO codes.
  ISO codes are important for international trade, reporting, and integration with external systems.
  If you are unsure about the correct ISO code, refer to the official ISO 80000 standard or consult your logistics/warehouse team.
  Sometimes, custom or non-standard UoMs are created without ISO codes; consider mapping them to standard UoMs if possible.
