• What is the cause and solution for SAP error message WWP1028 - Select the folder symbol for the node ?

  SAP Error Message:
  
  WWP1028: Select the folder symbol for the node
  
  Cause:
  This error typically occurs in SAP Web Dynpro applications when a user tries to expand or interact with a node in a tree or hierarchical structure, but instead of clicking on the folder symbol (the expand/collapse icon), they click directly on the node text or an area that does not trigger the expansion. The application expects the user to click the folder symbol to expand or collapse the node.
  In other words, the UI control is designed such that only clicking the folder icon (usually a small triangle or plus/minus sign) will expand or collapse the node. Clicking elsewhere on the node does not trigger this action, and the system prompts the user to "Select the folder symbol for the node."
  
  When does it happen?
  
  In Web Dynpro ABAP applications with tree controls.
  When users try to expand/collapse nodes by clicking on the node text or other parts instead of the folder icon.
  Sometimes it can also happen if the tree control is not properly configured to allow node expansion on clicking the node text.
  
  
  Solution:
  
  
  User Action:
  
  Simply click on the folder symbol (the small triangle or plus/minus icon) next to the node to expand or collapse it.
  Avoid clicking directly on the node text if the application requires clicking the folder symbol.
  
  
  
  Developer Action (if you are a developer or consultant):
  
  Check the Web Dynpro tree UI element configuration.
  Enable the property that allows node expansion on clicking the node text, if desired. This can be done by setting the tree control property expandOnNodeClick (or similar, depending on the Web Dynpro version).
  Ensure that the tree nodes are properly configured with folder symbols/icons.
  Review the event handlers for node selection and expansion to make sure they behave as expected.
  
  
  
  User Training:
  
  Inform users about the correct way to expand/collapse nodes in the tree control.
  Provide documentation or tooltips in the UI to guide users.
  
  
  
  
  Related Information:
  
  This message is a standard Web Dynpro message to guide users on how to interact with tree controls.
  It is not an error in the system but a user guidance message.
  If the behavior is inconvenient, developers can customize the tree control to improve usability.
  SAP Notes or documentation on Web Dynpro tree controls may provide additional configuration options.
