  The SAP error message G0026, which states "Multiple insertions of consolidation units in hierarchy &1," typically occurs in the context of financial consolidation processes within SAP. This error indicates that there are multiple entries for the same consolidation unit in a hierarchy, which is not allowed.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that the same consolidation unit has been entered multiple times in the same hierarchy. This can happen due to data entry errors or incorrect configuration.
  Hierarchy Configuration: The hierarchy may not be set up correctly, leading to the same unit being assigned to multiple parent nodes.
  Data Migration Issues: If data has been migrated from another system or if there have been recent changes to the hierarchy, duplicates may have been inadvertently created.
  
  Solution:
  
  Check Hierarchy Configuration: Review the hierarchy configuration in the SAP system to ensure that each consolidation unit is assigned only once. You can do this by navigating to the relevant hierarchy in the SAP GUI and checking for duplicates.
  Remove Duplicates: If duplicates are found, remove the extra entries. Ensure that each consolidation unit is linked to only one parent node in the hierarchy.
  Data Validation: Implement data validation checks to prevent duplicate entries in the future. This can include setting up validation rules or using reports to identify duplicates before they are saved.
  Consult Documentation: Refer to SAP documentation or help resources for specific steps on managing hierarchies and consolidation units.
  Testing: After making changes, test the hierarchy to ensure that the error does not reoccur and that the consolidation process can proceed without issues.
