• What is the cause and solution for SAP error message OH033 - Multi-dimension set contains field & more than once ?

  The SAP error message OH033, which states "Multi-dimension set contains field & more than once," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are working with multi-dimensional data models, such as InfoCubes or MultiProviders. This error indicates that a field (or characteristic) has been defined multiple times within a multi-dimensional structure, which is not allowed.
  Cause:
  
  Duplicate Fields: The most common cause of this error is that the same field or characteristic has been included more than once in the definition of a multi-dimensional object (like an InfoCube or MultiProvider).
  Incorrect Data Model Design: The design of the data model may have inadvertently led to the inclusion of the same field multiple times, either through joins or unions in the underlying data sources.
  Data Source Configuration: If you are using multiple data sources, it is possible that the same field is being pulled from different sources, leading to duplication.
  
  Solution:
  
  
  Check the Multi-Dimensional Object Definition:
  
  Go to the definition of the InfoCube or MultiProvider where the error is occurring.
  Review the list of fields/characteristics included in the object and ensure that no field is listed more than once.
  
  
  
  Remove Duplicate Fields:
  
  If you find any duplicate fields, remove the duplicates from the definition. Ensure that each field is only included once.
  
  
  
  Review Data Source Configuration:
  
  If you are using multiple data sources, check the configuration of each data source to ensure that they do not contain overlapping fields that could lead to duplication in the multi-dimensional object.
  
  
  
  Re-activate the Object:
  
  After making the necessary changes, re-activate the InfoCube or MultiProvider to ensure that the changes take effect.
  
  
  
  Test the Changes:
  
  Run a test query or data load to ensure that the error has been resolved and that the multi-dimensional object is functioning as expected.
