• What is the cause and solution for SAP error message WSTRN106 - Unidentified error has occured ?

  SAP Error Message:
  
  WSTRN106 - Unidentified error has occurred
  
  Cause:
  The error message WSTRN106 typically appears in SAP when there is an unexpected or unidentified error during a workflow or background process execution. It is a generic error indicating that the system encountered a problem it could not classify or handle properly. Common causes include:
  
  Issues in workflow container or task processing.
  Missing or incorrect configuration in workflow/customizing.
  Problems with the underlying function modules or BAPIs called by the workflow.
  Authorization or system environment issues.
  Data inconsistencies or missing master data required by the workflow.
  Runtime errors in custom code or user-exits/enhancements triggered by the workflow.
  
  Because the error is generic ("Unidentified error"), it usually means the system could not capture a more specific error message.
  
  Solution:
  To resolve WSTRN106, follow these steps:
  
  
  Check the Workflow Log:
  
  Use transaction SWI1 or SWI2_FREQ to find the workflow instance.
  Analyze the workflow log for detailed error messages or the step where the error occurred.
  Look for any error messages or dumps linked to the workflow task.
  
  
  
  Check Short Dumps:
  
  Use transaction ST22 to check for any ABAP short dumps that occurred at the time of the error.
  Analyze the dump to identify the root cause (e.g., missing data, authorization failures, runtime errors).
  
  
  
  Check System Logs:
  
  Use transaction SM21 to review system logs for any related errors or warnings.
  
  
  
  Review Custom Code:
  
  If the workflow calls custom function modules, BAPIs, or user-exits, review the code for possible exceptions or errors.
  Debug the workflow step if necessary.
  
  
  
  Check Authorizations:
  
  Verify that the user executing the workflow has the necessary authorizations.
  
  
  
  Check Configuration:
  
  Verify workflow customizing and container elements.
  Ensure all required data and master data are present and consistent.
  
  
  
  Apply SAP Notes:
  
  Search the SAP Support Portal for notes related to WSTRN106 or the specific workflow/task involved.
  Apply any relevant SAP Notes or patches.
  
  
  
  Reprocess or Restart Workflow:
  
  Sometimes restarting or reprocessing the workflow instance after fixing the root cause resolves the issue.

  Summary:
  WSTRN106 is a generic workflow error indicating an unidentified problem during workflow execution. The key to resolving it is to analyze the workflow log, check for ABAP dumps, review custom code, verify authorizations, and ensure proper configuration and data consistency. Applying relevant SAP Notes and debugging the workflow steps usually helps identify and fix the root cause.
