• What is the cause and solution for SAP error message /PLMI/GSS_SI2B012 - Change number &1 is valid before change number &2 ?

  The SAP error message /PLMI/GSS_SI2B012 Change number &1 is valid before change number &2 typically occurs in the context of change management or configuration management within SAP systems, particularly when dealing with change numbers in the context of engineering change management (ECM) or similar processes.
  Cause:
  This error indicates that there is a conflict in the sequence of change numbers. Specifically, it means that the change number you are trying to use (change number &2) is not valid because it is supposed to be applied before another change number (change number &1) that is already in effect. This can happen if:
  
  The change numbers are not applied in the correct order.
  There is a misconfiguration in the change management settings.
  The system is trying to apply a change that is not valid due to the existing change number's validity period.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Change Number Validity: Review the validity periods of both change numbers involved. Ensure that the change number you are trying to apply (change number &2) is indeed supposed to be applied after the existing change number (change number &1).
  
  
  Adjust Change Numbers: If the sequence is incorrect, you may need to adjust the change numbers. This could involve:
  
  Changing the validity dates of the change numbers.
  Deactivating or removing the conflicting change number if it is no longer needed.
  
  
  
  Consult Documentation: Refer to the SAP documentation or your organization's change management policies to understand the correct sequence and usage of change numbers.
  
  
  Check Configuration: Ensure that the configuration settings for change management in your SAP system are correctly set up. This may involve checking the configuration in transaction codes related to change management.
  
  
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide guidance based on your specific system configuration and business processes.
