  SAP Error Message:
  WD344: This node violates the block structure required
  
  Cause
  The error message WD344 typically occurs in the context of Web Dynpro ABAP applications. It indicates that the UI element tree structure (the node hierarchy) does not conform to the expected block structure rules required by the Web Dynpro framework.
  More specifically:
  
  The Web Dynpro UI elements are organized in a hierarchical tree structure.
  Certain UI elements (nodes) must be contained within specific container elements (blocks).
  If a node is placed outside of its required block or violates the expected nesting rules, the framework raises this error.
  This often happens when the UI element tree is manipulated programmatically or when the view layout is incorrectly defined in the Web Dynpro component.
  
  
  Common Scenarios Leading to WD344
  
  Adding UI elements dynamically in an incorrect order or outside of a container.
  Incorrect nesting of UI elements in the layout editor.
  Modifying the UI element tree in the code without respecting the block
