  The SAP error message RSOS_SEARCH226 typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the data model, particularly with the associations between InfoProviders (like InfoCubes, DataStore Objects, etc.). The message indicates that the alias of the left table in an association has been adjusted, which can happen due to changes in the underlying data model or structure.
  Cause:
  
  Changes in Data Model: The error often arises when there have been changes to the structure of the InfoProviders involved in the association. This could include renaming fields, changing data types, or modifying the InfoProvider itself.
  Inconsistent Metadata: If the metadata of the InfoProviders is not consistent or has not been updated properly after changes, it can lead to this error.

  Solution:
  
  Check Associations: Review the associations between the InfoProviders involved. Ensure that the fields and data types match as expected.
  Update Metadata: If there have been changes to the InfoProviders, make sure to update the metadata in the BW system. This can often be done by reactivating the InfoProvider or the associated objects.
