• What is the cause and solution for SAP error message WF110 - The workflow send module does not know method <&> ?

  SAP Error Message:
  
  WF110: The workflow send module does not know method <&>
  
  Cause:
  This error occurs in SAP Workflow when the workflow tries to send a message (trigger a method) to a Business Object, but the specified method is not recognized or does not exist in the Business Object Repository (BOR) for the given object type.
  In other words, the workflow is attempting to call a method that is either:
  
  Not defined in the BOR for the object type.
  Misspelled or incorrectly referenced in the workflow definition.
  The Business Object or method has been changed or deleted.
  The workflow container or binding is incorrect, causing the method call to fail.
  
  
  Explanation:
  
  The workflow send module is responsible for sending messages (method calls) to Business Objects.
  Each Business Object has a set of methods defined in the BOR.
  If the workflow tries to call a method that the BOR does not know, it raises WF110.
  The placeholder <&> in the error message is replaced by the method name that is unknown.
  
  
  Solution:
  
  
  Check the Method Name:
  
  Verify the method name used in the workflow step.
  Ensure it exactly matches the method name defined in the BOR (case-sensitive).
  
  
  
  Check the Business Object:
  
  Confirm that the Business Object used in the workflow step is correct.
  Use transaction SWO1 to display the Business Object and check its methods.
  
  
  
  Verify BOR Configuration:
  
  Use transaction SWO1 to check if the method exists for the Business Object.
  If the method is missing, it might need to be created or restored.
  
  
  
  Check Workflow Step Configuration:
  
  In the workflow builder (SWDD), check the step that sends the message.
  Ensure the correct method is selected.
  Check the container binding for the step to ensure the correct object instance is passed.
  
  
  
  Check for Transport or System Changes:
  
  If the workflow or BOR was recently changed or transported, verify that all changes are consistent and properly imported.
  
  
  
  Reimport or Repair BOR Objects:
  
  If the BOR object or method is corrupted or missing, reimport or repair it.
  
  
  
  Debugging:
  
  Use transaction SWUS or SWI1 to trace the workflow.
  Debug the workflow runtime to see where the method call fails.
  
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SWO1 - Business Object Builder (to check BOR objects and methods)
  SWDD - Workflow Builder (to edit workflow definitions)

  SAP Notes:
  
  Search SAP Support Portal for notes related to WF110 for specific versions or scenarios.
  
  
  
  Common Scenarios:
  
  Custom workflows calling custom BOR objects where methods were renamed or deleted.
  Standard workflows after system upgrades where BOR objects have changed.
