• What is the cause and solution for SAP error message WFCS060 - Interface to function module &1 supplied with incorrect data &2 &3 &4 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WFCS060: Interface to function module &1 supplied with incorrect data &2 &3 &4
  
  Meaning / Cause:
  This error occurs in the SAP Workflow system when the interface parameters passed to a function module (used in a workflow step) do not match the expected data types or structure. Essentially, the workflow is trying to call a function module with incorrect or incompatible data.
  
  &1 = Name of the function module.
  &2, &3, &4 = Details about the incorrect data supplied (e.g., parameter names, expected vs. supplied types).
  
  Common causes include:
  
  Mismatch between the workflow container elements and the function module interface parameters.
  Changes in the function module interface without updating the workflow.
  Incorrect mapping of container elements to the function module parameters.
  Data type incompatibility (e.g., passing a structure where a simple type is expected).
  
  
  Where it occurs:
  
  During the execution of a workflow step that calls a function module.
  When the workflow container elements are passed as input parameters to the function module.
  
  
  Solution / How to fix:
  
  
  Check the function module interface:
  
  Go to SE37 and display the function module &1.
  Note the import, export, and changing parameters and their data types.
  
  
  
  Check the workflow container elements:
  
  In the workflow builder (transaction SWDD), check the container elements used in the step calling the function module.
  Verify that the container elements mapped to the function module parameters have compatible data types.
  
  
  
  Adjust the container elements or mapping:
  
  If the container elements have incorrect types, either:
  
  Change the container element type to match the function module parameter.
  Or adjust the mapping in the workflow step to correctly map container elements to the function module parameters.
  
  
  
  
  
  Update the workflow if the function module interface changed:
  
  If the function module interface was changed (e.g., parameters added or removed), update the workflow step accordingly.
  
  
  
  Test the workflow step:
  
  After corrections, test the workflow step to ensure the function module is called with correct data.
  
  
  
  Use debugging if necessary:
  
  You can debug the workflow step to see what data is being passed to the function module.
  
  
  
  
  Additional Information:
  
  This error is related to the SAP Business Workflow component.
  The error message is raised by the workflow runtime when it tries to call the function module.
  Always ensure that the workflow container elements and the function module interface are synchronized.
  If you have transport or system copies, verify that the function module and workflow are consistent across systems.
