• What is the cause and solution for SAP error message EA476 - Extension & exists ?

  The SAP error message EA476 ("Extension & exists") typically occurs when there is an attempt to create or modify an extension (like a custom field or enhancement) that already exists in the system. This can happen in various contexts, such as when working with Business Add-Ins (BAdIs), enhancements, or custom fields in SAP.
  Cause:
  
  Duplicate Extension: The extension you are trying to create or modify already exists in the system.
