  SAP Error Message: WER_UI109
  
  Cause:
  The error message WER_UI109 typically occurs in the context of SAP Workflow or Business Workplace (SBWP) when there is an issue related to the user interface or workflow processing. Specifically, it often indicates that a required UI element or workflow container attribute is missing, incorrectly configured, or that the system cannot find the expected data or object during workflow execution or task processing.
  In many cases, WER_UI109 is triggered when:
  
  A workflow step tries to access a UI element that is not available or incorrectly referenced.
  The workflow container does not contain the expected data object or attribute.
  There is a mismatch between the workflow definition and the UI configuration.
  The user interface component (e.g., Web Dynpro, SAP GUI screen) linked to the workflow task is not properly assigned or is missing.
  
  
  Solution:
  To resolve the WER_UI109 error, consider the following steps:
  
  
  Check Workflow Container:
  
  Verify that all required container elements are correctly defined and populated.
  Use transaction SWI1 or SWI2_FREQ to analyze workflow logs and identify missing container elements.
  
  
  
  Review Workflow Task and UI Assignment:
  
  Ensure that the workflow task is correctly linked to the appropriate UI component.
  Check the task definition in transaction PFTC and verify the assignment of the dialog step or UI element.
  
  
  
  Verify UI Component Availability:
  
  Confirm that the UI component (e.g., Web Dynpro application, SAP GUI screen) exists and is active.
  If using Web Dynpro, check the component configuration and ensure it is correctly linked to the workflow.
  
  
  
  Check Authorization and User Settings:
  
  Make sure the user has the necessary authorizations to access the UI elements.
  Verify that the user’s Business Workplace (SBWP) is properly configured.
  
  
  
  Debug Workflow Execution:
  
  Use transaction SWI1 or SWI2_DIAG to trace the workflow execution.
  Debug the workflow step to see where the UI element or container attribute is missing.
