This error indicates that the system expects a specific order of data entries, where the section header data must precede the General Ledger (G/L) account items in the document.

  Solution:
  
  Check Data Entry Order: Review the document or data upload to ensure that the section header data is correctly positioned before the G/L account items. This may involve reordering the entries in the document.
  Correct Data Upload: If the error arises during a data upload (e.g., using LSMW or BAPIs), ensure that the mapping and sequence of the data fields are correctly defined.
  Review Configuration: If the issue persists, check the configuration settings related to document processing in the SAP system. Ensure that the settings align with the expected data structure.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on the expected structure of financial documents in your version of SAP.
