This can lead to performance issues when querying the InfoCube, as the absence of proper indexing can slow down data retrieval processes.
  Cause:
  
  Missing Indexes: The fact tables in the InfoCube may not have the necessary indexes created, which are essential for optimizing query performance.
  Obsolete Index Layout: The existing indexes may not be aligned with the current structure of the InfoCube, possibly due to changes in the data model or after a data load.
  Data Model Changes: If there have been changes to the InfoCube structure (like adding or removing characteristics), the existing indexes may become obsolete.
  Data Load Issues: If data loads have not been executed properly, it may lead to inconsistencies in the indexing.
  
  Solution:
  
  
  Rebuild Indexes: You can rebuild the indexes for the affected InfoCube. This can typically be done through the SAP BW transaction code RSA1 (Data Warehousing Workbench) or using the RSMO transaction for managing InfoCubes.

  Update Index Layout: If the index layout is obsolete, you may need to update it. This can involve adjusting the InfoCube structure or re-creating the indexes to match the current data model.
  
  
  Perform Data Load: After making changes to the indexes, perform a data load to ensure that the data is correctly indexed and that the InfoCube is up to date.
  
  
  Analyze Performance: After rebuilding the indexes, monitor the performance of queries against the InfoCube to ensure that the changes have had the desired effect.
