  WRETAIL_PROXY003 No data found
  
  Cause
  This error typically occurs in SAP Retail scenarios, especially when dealing with proxy communication between the SAP Retail system and external systems or services (such as POS systems, middleware, or other connected components).
  Possible causes include:
  
  
  Missing or Incorrect Data in the Source System:
  
  The proxy call expects certain data (e.g., master data, transaction data) to be available, but the data is missing or not found in the backend system.
  
  
  Incorrect or Incomplete Configuration:
  
  The proxy or interface might be incorrectly configured, leading to requests for data that does not exist or cannot be retrieved.
  
  
  Data Synchronization Issues:
  
  Data might not have been replicated or synchronized properly between systems, causing the proxy to fail when trying to fetch data.
  
  
  Incorrect Parameters in the Proxy Call:
  
  The input parameters sent to the proxy might be wrong or incomplete, resulting in no data being found.
  
  
  
  Solution
  To resolve the WRETAIL_PROXY003 No data found error, consider the following steps:
  
  
  Check the Data Availability:  
  
  Verify that the data requested by the proxy exists in the backend system. For example, check if the master data (articles, customers, etc.) or transactional data is present and active.
  Use transaction codes like MM03 (Display Material), VD03 (Display Customer), or relevant transactions to confirm data presence.
  
  
  
  Review Proxy Configuration:  
  
  Check the proxy setup in the SAP system (using transaction SPROXY or relevant configuration transactions).
  Ensure that the proxy interface is correctly mapped and configured.
  
  
  
  Validate Input Parameters:  
  
  Analyze the proxy request payload to ensure all required fields are correctly populated.
  Use tools like SAP Gateway Client (/IWFND/GW_CLIENT) or debugging to inspect the request.
  
  
  
  Check Data Synchronization:  
  
  If data replication is involved (e.g., between SAP ERP and SAP Retail), verify that the replication jobs have run successfully.
  Check ALE/IDoc monitoring (WE02, WE05) for any errors related to data transfer.
  
  
  
  Review Logs and Traces:  
  
  Check application logs (SLG1) for detailed error messages.
  Enable and analyze traces if necessary to pinpoint the issue.
