This error indicates that there is an attempt to aggregate items that do not belong to the same hierarchy level or declaration group, which is not allowed.
  Cause:

  Solution:
  
  
  Check Hierarchy Levels: Ensure that all items you are trying to aggregate belong to the same hierarchy level. You can do this by reviewing the hierarchy structure in the relevant master data (e.g., material master, product hierarchy).

  Consult Documentation: Review SAP documentation or help resources related to the specific module you are working with (e.g., SAP Retail, SAP S/4HANA) for more detailed guidance on hierarchy and declaration groups.
