    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:

    Adding UI elements dynamically in an incorrect order or outside of a container.
