Symptom
A consistent header could not be found while attempting to build report
row hierarchy &V1& from Customizing defined via transaction BWOM01.
A hierarchy must only contain one report row for which the <LS>Totals
Row</> field is not filled.
This row is the header row of the report row hierarchy.
The report row hierarchy that you defined not only contains row &V2&
but at least one other row for which the <LS>Totals Row</> is initial.
Error correction
Use transaction BWOM01 to make corrections to Customizing for the
report row hierarchy.

BWOM2011 - Details

• The SAP error message BWOM2011, which states "Report row hierarchy header is not unique," typically occurs in SAP Business Warehouse (BW) when there is an issue with the hierarchy structure of a report. This error indicates that there are duplicate entries in the hierarchy that are causing confusion in the report generation process.
  
  Cause:
  
  Duplicate Hierarchy Nodes: The most common cause of this error is that there are multiple nodes in the hierarchy that have the same name or identifier. This can happen if the hierarchy was not properly maintained or if there were changes made to the hierarchy structure without ensuring uniqueness.
  Incorrect Data Model: If the underlying data model has inconsistencies or if there are issues with the way the data is structured, it can lead to this error.
  Report Configuration: The configuration of the report itself may not be set up correctly, leading to conflicts in how the hierarchy is interpreted.
