• What is the cause and solution for SAP error message /PLMI/GSS_R2B016 - You cannot synchronize twice with the same change number ?

  The SAP error message /PLMI/GSS_R2B016 indicates that there is an attempt to synchronize data using the same change number more than once. This typically occurs in the context of SAP's Logistics and Supply Chain Management modules, particularly when dealing with change management and data synchronization processes.
  Cause:
  The error is caused by trying to perform a synchronization operation with a change number that has already been processed. In SAP, change numbers are used to track changes in data, and each change number should be unique for each synchronization operation. If the same change number is used again, the system prevents the operation to avoid inconsistencies and data integrity issues.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Change Number: Verify the change number you are trying to use for synchronization. Ensure that it has not already been processed. You can do this by checking the logs or the status of the change number in the relevant transaction.
  
  
  Use a New Change Number: If the change number has already been used, you will need to create a new change number for your synchronization operation. This can typically be done in the relevant transaction or configuration settings.
  
  
  Review Synchronization Process: Ensure that your synchronization process is correctly set up and that you are not inadvertently trying to synchronize the same data multiple times with the same change number.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the synchronization process relevant to your module or application.
  
  
  Check for Custom Code: If there are any custom developments or enhancements in your SAP system, review them to ensure they are not causing the issue by reusing change numbers.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. They may provide insights specific to your system configuration.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes that deal with change management and synchronization, such as C223 (Change Number Management) or C220 (Change Number Overview).
  SAP Notes: Check for any SAP Notes related to this error message or the synchronization process. SAP Notes often contain fixes or workarounds for known issues.
  System Logs: Review system logs (transaction SLG1) for additional error messages or warnings that may provide more context about the issue.
  
  By following these steps, you should be able to resolve the error and successfully perform the synchronization operation.
