• What is the cause and solution for SAP error message WFRE_CON301 - Error in Function &1 - Key &2 &3 &4 ?

  The SAP error message:
  WFRE_CON301: Error in Function &1 - Key &2 &3 &4
  is related to workflow runtime errors in SAP. Here's a detailed explanation of the cause, solution, and related information:
  
  Cause
  
  The error WFRE_CON301 occurs during the execution of a workflow when a function module (or method) called by the workflow runtime encounters an issue related to a key or identifier.
  The placeholders &1, &2, &3, and &4 are dynamically replaced by:
  
  &1: The name of the function module or method where the error occurred.
  &2, &3, &4: The key fields or identifiers related to the object or data that caused the error.
  
  
  This usually happens when the workflow tries to access or process an object instance (like a business object, task, or container element) that does not exist, is locked, or has inconsistent data.
  Common causes include:
  
  The workflow container element or object key is incorrect or missing.
  The referenced business object instance has been deleted or is not available.
  Authorization issues preventing access to the object.
  Inconsistent or incomplete data in the workflow container.
  The function module itself has an error or is not handling the input parameters correctly.
  
  
  
  
  Solution
  
  
  Check the Error Details:
  
  Look at the exact function module name and key values in the error message.
  Use transaction SWI1 (Work Item Selection) or SWI2_FREQ (Frequently Used Tasks) to find the workflow instance and work item related to the error.
  Use SWI5 or SWI6 to analyze the workflow log for the instance to get more context.
  
  
  
  Verify the Object Key:
  
  Check if the object key (&2 &3 &4) exists in the system.
  For example, if the key refers to a business object instance, verify it via transaction SWO1 or directly in the database tables.
  
  
  
  Check Workflow Container:
  
  Use transaction SWI3 or SWI2_DIAG to analyze the workflow container elements.
  Ensure that all required container elements are correctly filled and valid.
  
  
  
  Check Authorizations:
  
  Verify that the user executing the workflow has the necessary authorizations to access the object or function module.
  
  
  
  Debug the Function Module:
  
  If possible, debug the function module mentioned in the error to see why it fails with the given key.
  Check for any missing or incorrect parameters.
  
  
  
  Check for Locks or Inconsistencies:
  
  Sometimes, locks on the object or inconsistent data can cause this error.
  Use transaction SM12 to check for locks.
  Check the consistency of the business object data.
