• What is the cause and solution for SAP error message /BOBF/CONF403 - Structure &1 contains field name &2, which doesn't start with a letter ?

  The SAP error message /BOBF/CONF403 indicates that there is an issue with the structure definition in the Business Object Processing Framework (BOPF). Specifically, the error states that a field name in the structure does not start with a letter, which is a requirement in ABAP programming.
  Cause:
  
  Field Naming Convention: In ABAP, field names must start with a letter (A-Z or a-z). If a field name starts with a number or a special character, it violates the naming conventions and results in this error.
  Structure Definition: The structure in question may have been defined incorrectly, either in the data dictionary (SE11) or in the BOPF configuration.
  
  Solution:
  
  
  Check Structure Definition:
  
  Go to transaction SE11 (Data Dictionary).
  Look for the structure that is causing the error (replace &1 with the actual structure name).
  Review the field names in the structure and ensure that all field names start with a letter.
  
  
  
  Modify Field Names:
  
  If you find any field names that do not comply with the naming convention, rename them to start with a letter.
  Ensure that the new names are unique and do not conflict with existing field names.
  
  
  
  Re-activate the Structure:
  
  After making changes to the field names, activate the structure again to ensure that the changes take effect.
  
  
  
  Check BOPF Configuration:
  
  If the structure is part of a BOPF configuration, ensure that the BOPF configuration is updated to reflect any changes made to the structure.
  
  
  
  Test the Changes:
  
  After making the necessary changes, test the application or process that was generating the error to confirm that the issue has been resolved.
