• What is the cause and solution for SAP error message WD280 - Object type '&1' not valid ?

  SAP Error Message:
  
  WD280 Object type '&1' not valid
  
  Cause:
  This error occurs in the Web Dynpro ABAP environment when an invalid or unexpected object type is referenced or used. The placeholder &1 in the message is replaced by the actual object type name at runtime.
  Common scenarios include:
  
  Trying to use an object type that is not supported or recognized in the current context.
  Passing an incorrect object type to a Web Dynpro API or method.
  A mismatch between expected and actual object types in component usage or interface implementation.
  Corrupted or inconsistent Web Dynpro component metadata.
  
  
  Explanation:
  In Web Dynpro ABAP, object types refer to various entities like components, controllers, views, UI elements, or context nodes. The framework expects certain object types in specific places. If an object type is invalid or not allowed, the system raises this error to prevent runtime inconsistencies.
  
  Solution:
  
  
  Check the Object Type:
  
  Identify the actual object type passed in place of &1 in the error message.
  Verify if this object type is valid and supported in the context where it is used.
  
  
  
  Review the Code or Configuration:
  
  Inspect the Web Dynpro component or application code where the error occurs.
  Look for places where object types are referenced, such as:
  
  Component usage declarations
  Interface implementations
  Context node or attribute definitions
  UI element instantiations
  
  
  
  
  
  Correct the Object Type:
  
  Replace the invalid object type with a valid one.
  Ensure that the object type matches the expected type for the method or API being called.
  
  
  
  Check Component Metadata:
  
  Sometimes, inconsistencies in component metadata can cause this error.
  Try regenerating or reactivating the Web Dynpro component.
  Use transaction SE80 or WD_COMPONENT to check and fix component definitions.
  
  
  
  Debugging:
  
  Use the ABAP debugger to trace where the invalid object type is set or passed.
  Check call stacks and variable values to pinpoint the source.

  Summary:
  The error "WD280 Object type '&1' not valid" indicates that an invalid object type is being used in a Web Dynpro ABAP context. To resolve it, identify the invalid object type, verify its correctness, and adjust the code or configuration accordingly. Reactivating or regenerating the component may also help if metadata corruption is suspected.
