• What is the cause and solution for SAP error message CNV_20700003 - Mapping values are not considered in lexicographic scenario ?

  The SAP error message CNV_20700003 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there are mapping values that are not being considered in a lexicographic scenario, which can lead to issues in data consistency or integrity.
  Cause:
  The error is generally caused by one of the following reasons:
  
  
  Missing Mapping Entries: The mapping table may not have the necessary entries for the values being processed, leading to a situation where the system cannot find a corresponding value.
  
  
  Lexicographic Comparison Issues: The system is trying to perform a lexicographic comparison (i.e., comparing strings based on their alphabetical order), but the values being compared do not have a defined mapping.
  
  
  Data Format Issues: The data being processed may not be in the expected format, causing the mapping to fail.
  
  
  Configuration Issues: There may be configuration settings in the migration tool that are not set up correctly, leading to this error.
  
  
  Solution:
  To resolve the error CNV_20700003, you can take the following steps:
  
  
  Check Mapping Tables: Review the mapping tables used in the migration process to ensure that all necessary mappings are defined. Make sure that the values you are trying to map exist in the mapping table.
  
  
  Update Mapping Entries: If you find missing entries, add the necessary mappings to the mapping table. Ensure that the mappings are correct and correspond to the values being processed.
  
  
  Review Data Formats: Ensure that the data being migrated is in the correct format. If there are discrepancies in data types (e.g., numeric vs. string), correct them before re-running the migration.
  
  
  Check Configuration Settings: Review the configuration settings of the migration tool to ensure that they are set up correctly. This includes checking any parameters related to lexicographic comparisons.
  
  
  Consult Documentation: Refer to the SAP documentation or notes related to the specific migration tool you are using. There may be specific guidelines or known issues that can help you troubleshoot the error.
  
  
  Test with Sample Data: If possible, test the migration process with a smaller set of sample data to isolate the issue and verify that the mappings work as expected.
  
  
  Seek SAP Support: If the issue persists after trying the above steps, consider reaching out to SAP support for further assistance. They may have additional insights or patches that can help resolve the issue.
