This can occur during the activation of a DSO or when trying to load data into it. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Duplicate Indexes: The error arises when the system detects that two or more indexes defined for the DataStore Object are identical. This can happen due to incorrect configuration or changes made to the DSO structure that were not properly managed.
  Data Model Changes: If there have been recent changes to the DSO structure, such as adding or modifying fields, it may lead to the creation of duplicate indexes.
  Transport Issues: If the DSO was transported from one system to another, it might have led to inconsistencies in the index definitions.
  
  Solution:
  
  
  Check Index Definitions: 
  
  Go to the DataStore Object in the SAP BW modeling tools.

  Recreate the DSO:

  Backing up any necessary data.

  Transport Management:
