  SAP Error Message:
  WRPC_XI_PROXY007: The ISO UnitCode cannot be determined for unit &1
  
  
  Cause:
  This error occurs when the SAP system tries to process or map a unit of measure (UoM) but cannot find a corresponding ISO standard unit code for the given unit. The ISO UnitCode is required for integration scenarios, especially in SAP XI/PI/PO (Process Integration/Process Orchestration) or when using proxy communication where standardized unit codes are necessary for message exchange.
  In other words, the system has encountered a unit of measure (e.g., KG, M, L) that is not linked or mapped to an ISO standard unit code in the system's unit of measure configuration or in the integration mapping.
  
  Typical Scenarios:
  
  When sending or receiving IDocs, proxies, or messages that require ISO unit codes.
  During integration with external systems that expect ISO standardized units.
  When the unit of measure master data is incomplete or missing ISO
