  Error Message
  WSUBST004: No log data exists
  
  Cause
  This error typically occurs when you try to display or access a log related to a workflow or a background job, but the system cannot find any log entries for the specified object or process instance. In other words, the system is expecting log data (such as workflow logs, job logs, or change logs), but none are available.
  Common scenarios include:
  
  Attempting to view workflow logs for a workflow instance that has not yet generated any log entries.
  Trying to access job logs for a job that has not run or whose logs have been deleted.
  Accessing change logs or application logs where no entries exist for the selected criteria.
  
  
  Solution
  To resolve or handle this error, consider the following steps:
  
  
  Verify the Object or Instance:
  
  Ensure that the workflow instance, job, or object you are trying to view logs for actually exists and has been executed.
  Check if the process or job has started and completed, as logs are usually created after execution.
  
  
  
  Check Log Retention and Deletion:
  
  Logs might have been deleted due to log retention policies or manual cleanup.
  Verify if log deletion jobs (e.g., report RSPCMDEL for workflow logs) have run recently and removed old logs.
  
  
  
  Adjust Selection Criteria:
  
  When searching for logs, broaden the selection criteria (e.g., date range, object ID) to ensure you are not filtering out existing logs.
  
  
  
  Trigger the Process:
  
  If the workflow or job has not yet run, trigger or restart it to generate logs.
  
  
  
  Check System Settings:
  
  Ensure that logging is enabled for the relevant application or workflow.
  For workflows, check transaction SWU3 (Workflow Customizing) to verify that workflow logging is active.
  
  
  
  Use Appropriate Transactions:
  
  For workflow logs: Use SWI1 or SWI2_DIAG to search for workflow logs.
  For job logs: Use SM37 to check job status and logs.
  For application logs: Use SLG1 to view logs.
  
  
  
  
  Related Information
  
  
  Workflow Logs:
  
  Workflow logs are created when a workflow instance is processed.
  If a workflow is stuck or not started, no logs will be available.
  Transaction SWI1 can be used to search for workflow logs by various criteria.
  
  
  
  Job Logs:
  
  Job logs are generated after a background job runs.
  If a job is scheduled but not yet executed, no logs exist.
  Use SM37 to check job status and access logs.
  
  
  
  Log Retention:
  
  SAP systems often have log retention policies to delete old logs to save space.
  Check if logs have been deleted by system jobs or administrators.
  
  
  
  SAP Notes:
  
  Sometimes, specific SAP Notes address issues related to missing logs or log display problems.
  Check the SAP Support Portal for notes related to WSUBST004 or log display issues.
