• What is the cause and solution for SAP error message /SAPCND/GEN_CODE109 - '&1' is not a valid name for an index for database table &2 ?

  The SAP error message /SAPCND/GEN_CODE109 '&1' is not a valid name for an index for database table &2 typically indicates that there is an issue with the naming convention of an index being created or referenced in the context of a database table. This error is often encountered during the generation of database objects or when working with database table definitions in the ABAP Dictionary.
  Cause:
  
  
  Invalid Index Name: The name provided for the index (&1) does not conform to the naming conventions required by the database or SAP. This could be due to:
  
  Special characters or spaces in the index name.
  The index name being too long (exceeding the maximum length allowed).
  The index name starting with a number or containing invalid characters.
  
  
  
  Database Constraints: The database system may have specific constraints on index names that are not being met.
  
  
  Configuration Issues: There may be issues with the configuration of the database or the SAP system that are causing the index name to be rejected.
  
  
  Solution:
  
  
  Check Naming Conventions: Ensure that the index name follows the naming conventions for SAP and the underlying database. Typically, index names should:
  
  Start with a letter.
  Contain only alphanumeric characters and underscores.
  Be within the length limits (usually 30 characters for SAP).
  
  
  
  Modify the Index Name: If you have control over the index name, modify it to meet the required standards. You can do this in the ABAP Dictionary (transaction SE11) where the database table is defined.
  
  
  Review Database Settings: If the issue persists, check the database settings and configurations to ensure that they are compatible with SAP's requirements.
  
  
  Re-generate Objects: After making the necessary changes, try to regenerate the database objects or the relevant program to see if the error is resolved.
  
  
  Consult Documentation: Refer to SAP documentation or the specific database documentation for any additional constraints or requirements regarding index naming.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE11 (Data Dictionary), SE14 (Database Utility), or SE80 (Object Navigator) to investigate and modify the database table and index definitions.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance.
  Database Documentation: If you are using a specific database (e.g., HANA, Oracle, SQL Server), consult the documentation for that database regarding index naming conventions.
  
  By following these steps, you should be able to resolve the error and successfully create or reference the index for the specified database table.
