  The SAP error message LD400: No buffers can be inserted at the top level typically occurs in the context of SAP's Logistics Data (LD) or when dealing with certain data structures in the SAP system, particularly when working with hierarchical data or buffer management.

  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the data structure or process you are working with. This may provide insights into the correct usage and limitations.
