• What is the cause and solution for SAP error message CNV_20100389 - SKB1 (sequence number &1) must run before &2 (sequence number &3); error ?

  The SAP error message CNV_20100389 indicates a sequence dependency issue during a data migration or conversion process, specifically in the context of the SAP S/4HANA migration or similar data transformation projects. This error typically arises when a specific step (or sequence number) in the migration process must be completed before another step can be executed.
  Cause:
  The error occurs because the system has detected that a prerequisite step (identified by sequence number &1) has not been executed before attempting to run the current step (identified by sequence number &2). The sequence numbers represent the order in which the migration steps must be performed, and skipping or incorrectly ordering these steps can lead to this error.
  Solution:
  To resolve this error, follow these steps:
  
  
  Identify the Steps: Check the migration or conversion documentation to identify what the sequence numbers &1 and &2 correspond to. This will help you understand which steps are involved.
  
  
  Run the Prerequisite Step: Execute the step associated with sequence number &1. Ensure that it completes successfully before proceeding to the next step.
  
  
  Check for Dependencies: Review the migration plan or documentation for any additional dependencies that may not be immediately obvious. Ensure that all prerequisite steps are completed in the correct order.
  
  
  Re-run the Current Step: After successfully completing the prerequisite step, attempt to run the step associated with sequence number &2 again.
  
  
  Consult Logs and Documentation: If the error persists, check the logs for more detailed error messages that may provide additional context. Review the migration documentation for any specific instructions or notes regarding the steps.
  
  
  Seek Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with a professional who has experience with SAP migrations.
