  Error Message
  WP207 - ISO unit of measurement not maintained for material &
  
  Cause
  This error occurs because the system requires an ISO unit of measurement (UoM) to be maintained for the material in question, but it has not been maintained in the material master data. The ISO unit of measurement is necessary for certain processes, especially when dealing with international standards, integration scenarios, or specific SAP modules that rely on standardized units.
  
  Explanation
  
  The ISO unit of measurement is a standardized code defined by the International Organization for Standardization (ISO) to uniquely identify units of measure.
  SAP uses these ISO codes to ensure consistency and interoperability, especially in cross-system or cross-company scenarios.
  If the ISO unit is missing, SAP cannot correctly interpret or convert the unit of measure for the material, leading to this error.
  
  
  Where to Maintain ISO Unit of Measurement
  The ISO unit of measurement is maintained in the Material Master under the Basic Data 1 view.
  
  Solution / How to Fix
  
  Go to the Material Master:
  
  Transaction code: MM02 (Change Material)
  
  
  Enter the material number and select the view "Basic Data 1".
  Locate the field "ISO Unit of Measure" (ISO UoM):
  
  This field is usually near the "Base Unit of Measure" field.
  
  
  Enter the correct ISO unit code corresponding to the base unit of measure.
  
  For example:
  
  EA (Each)
  KG (Kilogram)
  M (Meter)
  L (Liter)
  
  
  The list of ISO codes is standardized and can be found in SAP documentation or ISO standards.
  
  
  Save the material master record.
  
  
  Additional Information
  
  If you are unsure about the correct ISO unit code, refer to SAP Note or the official ISO 80000 standard.
  The ISO unit of measurement is important for integration with external systems, EDI, and compliance with international standards.
  Sometimes, this error can appear during processes like goods movement, production order processing, or sales order creation if the system tries to validate the unit of measure against the ISO code.
