• What is the cause and solution for SAP error message WXCM100 - No function module stored for attribute &1, context structure &2 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WXCM100 No function module stored for attribute &1, context structure &2
  
  Cause:
  This error occurs in the Web Dynpro ABAP environment when the system tries to execute a function module associated with a context attribute, but no function module has been assigned or stored for that attribute in the component controller or context node.
  In Web Dynpro, attributes in the context can have associated function modules for certain operations (like value help, input validation, or other custom logic). If the framework expects a function module to be linked to an attribute but finds none, it raises this error.
  Typical scenarios causing this error:
  
  A context attribute is configured to use a function module (e.g., for value help or input help), but the function module name is missing or not maintained.
  The function module was deleted or renamed but the context attribute still references the old name.
  Incorrect or incomplete configuration in the Web Dynpro component or view.
  
  
  Solution:
  
  
  Check the context attribute configuration:
  
  Open the Web Dynpro component in the Web Dynpro Explorer.
  Navigate to the context node and find the attribute mentioned in the error message (&1).
  Verify if a function module is assigned to this attribute (e.g., in the attribute properties or in the value help configuration).
  
  
  
  Assign or correct the function module:
  
  If no function module is assigned but one is required, assign the correct function module.
  If the function module name is incorrect or outdated, update it to the correct function module.
  
  
  
  Verify the function module existence:
  
  Use transaction SE37 to check if the function module exists and is active.
  If missing, create or restore the function module as needed.
  
  
  
  Check the context structure:
  
  The error message also references the context structure (&2).
  Ensure that the context structure and its attributes are correctly defined and consistent with the function module's interface.
  
  
  
  Rebuild and activate the Web Dynpro component:
  
  After making changes, activate the component and test the application again.
  
  
  
  Debugging:
  
  If the problem persists, debug the Web Dynpro application to see where the function module call is triggered.
  Check the call stack and context attribute values.
