• What is the cause and solution for SAP error message WG121 - No additional data exists ?

  Certainly! Here's a detailed explanation for the SAP error message WG121 - No additional data exists:
  
  SAP Error Message: WG121 - No additional data exists
  
  Cause:
  The error message WG121 typically occurs in the context of SAP Workflow or SAP Business Workplace (SBWP) when the system tries to access or display additional data related to a workflow task, work item, or a related object, but no such additional data is found or available.
  More specifically:
  
  The workflow container or the work item does not contain the expected additional data.
  The system is trying to retrieve supplementary information (e.g., attachments, long texts, or other extended attributes) that have not been maintained or linked.
  The workflow step or task might be incomplete or incorrectly configured, leading to missing data.
  Sometimes, this can happen if the workflow or work item has been deleted or corrupted.
  
  
  When does it occur?
  
  When a user tries to display or process a workflow task and the system attempts to fetch additional data that is not present.
  When accessing the "Additional Data" tab or related UI elements in the SAP Business Workplace.
  During workflow debugging or analysis if the workflow container variables are empty or missing.
  
  
  Solution:
  
  
  Check Workflow Configuration:
  
  Verify that the workflow step/task is correctly configured to pass or maintain the additional data.
  Ensure that the container elements expected to hold additional data are properly filled during the workflow execution.
  
  
  
  Verify Workflow Container Data:
  
  Use transaction SWI1 (Work Item Selection) or SWI5 to find the work item.
  Use SWI6 or SWI3 to display the workflow container and check if the additional data elements exist and are populated.
  
  
  
  Check for Missing Attachments or Texts:
  
  If the additional data refers to attachments or long texts, verify that these objects exist and are linked to the workflow or business object.
  
  
  
  Recreate or Restart Workflow:
  
  If the workflow is corrupted or incomplete, consider restarting or recreating the workflow instance.
  
  
  
  Check Authorizations:
  
  Sometimes, the user may not have sufficient authorization to view the additional data, leading to this message. Verify user roles and authorizations.
  
  
  
  SAP Notes and Support:
  
  Search for relevant SAP Notes using the message number WG121 or related workflow issues.
  If the problem persists, consider raising a support ticket with SAP, providing workflow logs and details.

  Summary:
  The error WG121 - No additional data exists means the system expected to find supplementary data related to a workflow task or work item but found none. The resolution involves verifying workflow configuration, container data, attachments, and authorizations to ensure the additional data is correctly maintained and accessible.
