• What is the cause and solution for SAP error message RSOS_SEARCH225 - TAB_ALIAS of left table of association is wrong (is &1, should be &2) ?

  The SAP error message RSOS_SEARCH225 indicates that there is an issue with the alias of the left table in an association within a query or data model. Specifically, the error message states that the alias of the left table is incorrect, showing the current alias (&1) and the expected alias (&2).
  Cause:
  This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA when there is a mismatch between the expected table alias in a query or data model and the actual alias being used. Common causes include:
  
  Incorrect Alias Definition: The alias for the left table in the association may have been defined incorrectly in the data model or query.
  Changes in Data Model: If the data model has been modified (e.g., changes in InfoObjects, InfoProviders, or queries), it may lead to inconsistencies in the aliases.
  Transport Issues: If the data model was transported from one system to another, the alias might not have been updated correctly.
  Query Designer Issues: Sometimes, issues in the Query Designer can lead to incorrect associations being created or maintained.
  
  Solution:
  To resolve the RSOS_SEARCH225 error, you can follow these steps:
  
  
  Check the Data Model:
  
  Open the data model (e.g., InfoProvider, CompositeProvider) in the SAP BW or HANA modeling environment.

  Update the Query:

  Check the associations and ensure that the left table's alias is correctly defined.
  
  
  
  Recreate the Association:
  
  If the alias is incorrect and cannot be easily fixed, consider deleting the association and recreating it with the correct alias.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, check the transport logs and ensure that all objects were transported correctly. You may need to re-transport the affected objects.
  
  
  
  Test the Query:
  
  After making the necessary changes, test the query or data model to ensure that the error is resolved.
