• What is the cause and solution for SAP error message MEREP_01202 - Duplicated synchronization key &1 sent from mobile device ?

  The SAP error message MEREP_01202 indicates that there is a duplicated synchronization key being sent from a mobile device. This typically occurs in the context of SAP Mobile Platform or SAP Mobile Services, where data synchronization between the mobile device and the backend system is managed.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Duplicate Data Entry: The mobile device is attempting to send data that has already been sent previously, leading to a conflict in synchronization.
  Network Issues: Intermittent network connectivity may cause the same data to be sent multiple times.
  Application Logic: The mobile application may not be handling the synchronization process correctly, leading to repeated submissions of the same data.
  Data Caching: The mobile application may be caching data incorrectly, causing it to resend the same synchronization key.
  
  Solution:
  To resolve the MEREP_01202 error, consider the following steps:
  
  
  Check for Duplicates: Ensure that the data being sent from the mobile device does not already exist in the backend system. You may need to implement checks in the mobile application to prevent duplicate submissions.
  
  
  Review Application Logic: Examine the mobile application code to ensure that it correctly handles synchronization and does not attempt to send the same data multiple times.
  
  
  Network Stability: Ensure that the mobile device has a stable network connection. If the network is unstable, consider implementing retry logic with a back-off strategy to avoid resending the same data.
  
  
  Clear Cache: If the mobile application uses caching, ensure that the cache is cleared appropriately after a successful synchronization to prevent resending the same data.
  
  
  Error Handling: Implement robust error handling in the mobile application to manage synchronization errors gracefully and provide feedback to the user.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific mobile application or platform you are using for any additional troubleshooting steps or best practices.
  
  
  Logs and Monitoring: Check the logs on both the mobile device and the backend system to identify any patterns or specific instances that lead to the duplication error.
  
  
  Related Information:
  
  SAP Mobile Platform: Understanding how the SAP Mobile Platform handles data synchronization can provide insights into managing synchronization keys effectively.
  SAP Notes: Check for any relevant SAP Notes or updates that may address known issues related to this error.
