• What is the cause and solution for SAP error message CNV_10020629 - Cluster block &1: min value is not greater than predecessor max value ?

  The SAP error message CNV_10020629 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is an issue with the sequence of data being processed, specifically that the minimum value of a cluster block is not greater than the maximum value of the preceding block. This can lead to inconsistencies in the data being migrated.
  Cause:
  
  Data Overlap: The error usually arises when there are overlapping ranges in the data being migrated. For example, if you have a range of values for one block that ends at a certain point, and the next block starts at or before that point, it creates a conflict.
  Incorrect Data Preparation: The data being migrated may not have been properly prepared or validated before the migration process, leading to inconsistencies.
  Configuration Issues: There may be issues with the configuration of the migration settings or the mapping of fields between the source and target systems.
  
  Solution:
  
  Review Data Ranges: Check the data ranges for the blocks involved in the migration. Ensure that the minimum value of the current block is indeed greater than the maximum value of the preceding block.
  Data Cleansing: Cleanse the data to remove any overlaps or inconsistencies. This may involve adjusting the values in the source data or reconfiguring how the data is being grouped into blocks.
  Adjust Migration Settings: Review the migration settings and mappings to ensure they are correctly configured. This may involve adjusting the logic used to determine how data is grouped and processed.
  Testing: After making adjustments, perform a test migration with a smaller dataset to ensure that the issue has been resolved before attempting a full migration.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using for any additional guidance or known issues.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
