  SAP Error Message:
  WFRE_CON100 Error in Function &1 at OP- Header &2
  
  Meaning / Cause:
  
  This error occurs in the SAP Workflow Engine.
  It indicates that an error happened during the execution of a function module (or method) within a workflow container operation.
  The placeholder &1 represents the name of the function module or method where the error occurred.
  The placeholder &2 refers to the operation header or the specific container operation in the workflow where the error was detected.
  Common causes include:
  
  Incorrect or missing data in the workflow container.
  The function module called by the workflow is not active, missing, or has runtime errors.
  Authorization issues preventing the function module from executing properly.
  Inconsistent or incorrect workflow configuration.
  System or interface errors during the workflow execution.
  
  
  
  
  Where it Occurs:
  
  During the execution of a workflow step that involves container operations.
  When the workflow engine tries to execute a function module or method to manipulate container data or perform an operation.
  
  
  How to Analyze:
  
  
  Check the Workflow Log:
  
  Use transaction SWI1 or SWI2_FREQ to find the workflow instance and analyze the log.
  Look for the step where the error occurred and check the detailed error message.
  
  
  
  Identify the Function Module:
  
  From the error message, note the function module name (&1).
  Test the function module independently in SE37 to see if it runs without errors.
  
  
  
  Check Container Data:
  
  Verify the data passed to the function module in the workflow container.
  Use transaction SWO1 to check the workflow container structure.
  Ensure all required container elements are correctly filled.
  
  
  
  Check Authorization:
  
  Verify that the user executing the workflow has the necessary authorizations to run the function module.
  
  
  
  Check Workflow Configuration:
  
  Review the workflow definition in SWDD.
  Check the container operation step and ensure it is correctly configured.
  
  
  
  Check System Logs:
  
  Use transaction SM21 or ST22 to check for system dumps or errors related to the function module.
  
  
  
  
  Possible Solutions:
  
  
  Fix the Function Module:
  
  If the function module has errors, debug and correct them.
  Ensure the function module is active and properly transported.
  
  
  
  Correct Container Data:
  
  Make sure the workflow container has all required data elements filled with valid data.
  Adjust the workflow logic if necessary to populate container elements correctly.
  
  
  
  Adjust Authorizations:
  
  Provide the necessary authorizations to the workflow user or background user.
  
  
  
  Modify Workflow Configuration:
  
  Correct the container operation step in the workflow.
  If the operation is obsolete or incorrect, update or replace it.
  
  
  
  Debug the Workflow:
  
  Use transaction SWUD or SWI1 with debugging enabled to step through the workflow execution.
