• What is the cause and solution for SAP error message CNV_20700215 - Length of following New Material is/are greater than desired length (&1): ?

  The SAP error message CNV_20700215 indicates that the length of a new material number exceeds the maximum length defined in the system. This error typically arises during data migration or when creating new materials in the SAP system, especially when using tools like SAP S/4HANA Migration Cockpit or during data uploads.
  Cause:
  
  Material Number Length Exceeded: The new material number being created or imported exceeds the maximum length allowed by the system configuration. For example, in SAP ECC, the standard length for material numbers is 18 characters, while in S/4HANA, it can be up to 40 characters depending on the configuration.
  Incorrect Data Mapping: During data migration, the mapping of fields may not align correctly, leading to longer material numbers being generated.
  Data Source Issues: The source data may contain material numbers that are longer than the allowed length in the target SAP system.
  
  Solution:
  
  Check Material Number Length: Verify the maximum allowed length for material numbers in your SAP system configuration. You can check this in the material master settings or by consulting with your SAP Basis or configuration team.
  Adjust Data: If the material numbers in your source data exceed the allowed length, you will need to truncate or modify them to fit within the defined limits. This may involve:
  
  Shortening the material numbers.
  Creating a new naming convention that adheres to the length restrictions.
  
  
  Data Mapping Review: Review the data mapping in your migration tool to ensure that the fields are correctly aligned and that no unnecessary concatenation or formatting is causing the length to exceed the limit.
  Use Alternative Identifiers: If the material numbers are inherently long due to business requirements, consider using alternative identifiers or a different field for unique identification that complies with the length restrictions.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on material number configurations.
  Documentation: Review the SAP documentation for material master data management and migration processes to ensure compliance with best practices.
  Testing: After making adjustments, conduct thorough testing to ensure that the changes resolve the error and that the material numbers are created successfully without further issues.
  
  If the problem persists after following these steps, it may be beneficial to consult with SAP support or your internal SAP team for further assistance.
