• What is the cause and solution for SAP error message WWP1025 - Only select objects with traffic lights, however not the lowest level. ?

  SAP Error Message:
  
  WWP1025 – Only select objects with traffic lights, however not the lowest level.
  
  Cause
  This error occurs in SAP Web Dynpro applications, particularly in scenarios involving hierarchical data structures with traffic light indicators (status icons). The message indicates that the user or the application tried to select objects (nodes) that are at the lowest level of the hierarchy, but the selection logic or the application design expects only higher-level nodes (parent nodes) that have traffic lights (status indicators).
  In other words, the application or component is designed to allow selection only of nodes that have traffic lights and are not leaf nodes (lowest level nodes). Selecting leaf nodes or nodes without traffic lights violates this rule, triggering the error.
  
  When does it typically occur?
  
  In hierarchical views (e.g., organizational structures, process steps, or any tree-like UI) where nodes have traffic light status indicators.
  When the user tries to select leaf nodes (lowest level nodes) which do not have traffic lights.
  When the application logic expects selection only on nodes that have traffic lights and are not the lowest level.
  
  
  Solution
  
  
  User Action:
  
  Select only those nodes in the hierarchy that have traffic lights and are not leaf nodes.
  Avoid selecting the lowest level nodes or nodes without traffic lights.
  
  
  
  Developer/Administrator Action:
  
  Review the selection logic in the Web Dynpro component or application.
  Ensure that the selection handler filters out lowest level nodes or nodes without traffic lights before processing.
  If the business requirement allows selecting leaf nodes, adjust the logic to handle such cases appropriately.
  Check the configuration of the hierarchical data and traffic light assignment to ensure consistency.
  
  
  
  Technical Checks:
  
  Debug the Web Dynpro application to identify where the selection validation occurs.
  Verify the data model to confirm which nodes have traffic lights and which are lowest level.
  Adjust the UI or backend logic to prevent invalid selections or to handle them gracefully.
