• What is the cause and solution for SAP error message CNV_20700053 - Lexicographical MATNR is active. Check for leading zeros not necessary ?

  The SAP error message CNV_20700053 indicates that there is an issue related to the material number (MATNR) in the context of data conversion or migration. This error typically arises during data migration processes, especially when using SAP's data migration tools or during the execution of conversion programs.
  Cause:
  The error message suggests that the system has detected that the lexicographical representation of the material number (MATNR) is active, and it is indicating that leading zeros are not necessary. This can occur due to the following reasons:
  
  Leading Zeros in Material Numbers: The material numbers may have leading zeros that are not required or expected in the target system or format.
  Data Format Mismatch: The source data may have a different format than what the target system expects, leading to issues during the conversion process.
  Configuration Settings: There may be configuration settings in the SAP system that dictate how material numbers should be treated, particularly regarding leading zeros.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Material Number Format:
  
  Review the material numbers in your source data to ensure they conform to the expected format in the target system.
  If leading zeros are not necessary, consider removing them from the material numbers in the source data.
  
  
  
  Adjust Data Mapping:
  
  If you are using a data migration tool, check the mapping settings to ensure that the material number field is correctly configured to handle leading zeros.
  Ensure that the data types and lengths are consistent between the source and target systems.
  
  
  
  Configuration Review:
  
  Review the configuration settings in the SAP system related to material number handling. This may involve checking the settings in transaction codes like OMT0 (for material types) or OMR6 (for number ranges).
  Ensure that the settings align with the requirements of your data migration.
  
  
  
  Testing:
  
  After making the necessary adjustments, perform a test migration with a small subset of data to verify that the issue has been resolved.
  Monitor for any additional errors that may arise during the migration process.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration tool you are using, as there may be additional guidance or known issues related to this error.
  
  
  
  Related Information:
