• What is the cause and solution for SAP error message WPRO_XI_PROXY055 - Unit code from EAN/UPC conversion &1 deviates from unit code &2 ?

  Certainly! Here's a detailed explanation of the SAP error message:
  
  SAP Error Message:
  WPRO_XI_PROXY055: Unit code from EAN/UPC conversion &1 deviates from unit code &2
  
  Meaning / Cause:
  This warning message occurs during the processing of IDocs or proxy messages involving material master data or product information, particularly when handling unit of measure (UoM) conversions related to EAN/UPC codes.
  
  The system tries to convert an EAN/UPC code to a unit of measure.
  The unit of measure derived from the EAN/UPC code (&1) does not match the expected or predefined unit of measure (&2) in the system.
  This discrepancy indicates a mismatch between the unit of measure encoded in the barcode (EAN/UPC) and the unit of measure stored or expected in SAP for the material.
  
  
  Typical Scenarios:
  
  When integrating with external systems or suppliers who send product data including barcodes.
  During inbound IDoc processing (e.g., MATMAS, PRODAT) or proxy interfaces where product units are exchanged.
  When the EAN/UPC master data is maintained incorrectly or inconsistently.
  When the material master unit of measure settings differ from the unit encoded in the barcode.
  
  
  Impact:
  
  The warning indicates a potential data inconsistency.
  It may cause incorrect quantity or unit handling in downstream processes.
  Usually, it does not stop the process but should be reviewed to avoid future errors.
  
  
  Solution / How to Fix:
  
  
  Check the Material Master Data:
  
  Verify the base unit of measure (Base UoM) and alternative units of measure in transaction MM03.
  Check if the unit of measure (&2) matches the expected unit for the material.
  
  
  
  Check EAN/UPC Master Data:
  
  Use transaction MM03 or EAN13 maintenance to verify the unit of measure assigned to the EAN/UPC code (&1).
  Ensure that the unit of measure assigned to the barcode matches the material master unit of measure or is properly mapped.
  
  
  
  Adjust Unit of Measure Mapping:
  
  If the EAN/UPC unit code is incorrect, correct it in the barcode master data.
  If the material master unit of measure is incorrect, adjust it accordingly.
  If both are correct but differ due to business reasons, consider maintaining a conversion factor or mapping in the system.
  
  
  
  Review Conversion Settings:
  
  Check if there are any custom conversions or user exits that handle EAN/UPC to UoM mapping.
  Adjust or enhance the logic if necessary.
  
  
  
  Communicate with Data Providers:
  
  If data comes from external vendors or systems, inform them about the inconsistency.
  Request correct unit of measure information in the EAN/UPC data.

  Notes / SAP KBAs:
  
  Check SAP Notes related to EAN/UPC and unit of measure inconsistencies.
  Sometimes, SAP provides patches or corrections for specific interface scenarios.
  
  
  
  
  Summary:
  The warning WPRO_XI_PROXY055 indicates a mismatch between the unit of measure derived from an EAN/UPC code and the unit of measure expected in SAP for the material. To resolve it, verify and align the unit of measure in the material master and the EAN/UPC master data, and ensure consistent data exchange with external systems.
