• What is the cause and solution for SAP error message WRETAIL_PROXY005 - invalid language. ?

  SAP Error Message:
  
  WRETAIL_PROXY005 invalid language
  
  Cause:
  This error typically occurs in SAP Retail scenarios when a language code passed to a proxy or interface is not recognized or is invalid. The system expects a valid language key (usually a two-character language code like EN, DE, FR, etc.), but the value provided does not match any language defined in the system or the proxy interface.
  Common causes include:
  
  The language code sent from the front-end or external system is incorrect or missing.
  The language is not maintained in the SAP system (transaction SMLT).
  The proxy or interface expects a specific language format, and the input does not conform.
  Custom developments or middleware incorrectly map or transform language codes.
  
  
  Solution:
  
  
  Check the Language Code:
  
  Verify the language code being sent in the proxy call or interface.
  Ensure it matches one of the valid language keys maintained in SAP.
  
  
  
  Maintain Language in SAP:
  
  Use transaction SMLT to check if the language code exists.
  If missing, add the required language.
  
  
  
  Review Proxy or Interface Configuration:
  
  Check the proxy definition in transaction SPROXY.
  Validate the data mapping and ensure the language field is correctly populated.
  
  
  
  Check Middleware or Front-end Systems:
  
  If the language code comes from an external system, verify the mapping and transformation logic.
  Correct any discrepancies in language code formats.
  
  
  
  Debugging:
  
  Use transaction SLG1 to check application logs for more details.
  Debug the proxy or BAdI implementation to see where the language code is validated.
