• What is the cause and solution for SAP error message W3_API302 - Dynpro names can contain only digits ?

  SAP Error Message:
  W3_API302 Dynpro names can contain only digits
  
  
  Cause:
  This error occurs when a Dynpro (screen) name contains characters other than digits. In SAP Web Dynpro ABAP, screen (dynpro) names are expected to be numeric only. If the system encounters a dynpro name with alphabetic or special characters, it raises this error.
  Typically, this happens during:
  
  Web Dynpro application development or runtime when the system tries to reference a dynpro name.
  Transport or import of Web Dynpro components where dynpro names are incorrectly defined.
  Custom coding or manual changes where dynpro names are assigned or manipulated incorrectly.
  
  
  Explanation:
  
  Dynpro names in Web Dynpro ABAP are numeric strings (e.g., "0100", "0200").
  The system validates these names to ensure they contain only digits.
  If a dynpro name contains letters or other characters, the system throws the W3_API302 error.
  
  
  
  Solution:
  
  
  Check Dynpro Names:
  
  Review the dynpro names in your Web Dynpro component.
  Ensure all dynpro names are numeric only (e.g., "0100", "0200").
