• What is the cause and solution for SAP error message RSO_BOIS601 - Query with two structures is not supported ?

  The SAP error message RSO_BOIS601 indicates that a query is attempting to use two structures, which is not supported in the context of the query being executed. This typically occurs in SAP BW (Business Warehouse) when you are trying to create or execute a query that involves multiple data structures or InfoProviders that are not compatible with each other.
  Cause:
  
  Multiple Structures: The query is designed to pull data from two different structures (e.g., InfoCubes, DataStore Objects) that cannot be combined in the way the query is structured.
  Query Design: The query might be incorrectly designed, where the underlying data model does not support the combination of the two structures.
  Incompatibility: The characteristics or key figures from the two structures may not align properly, leading to conflicts in the query execution.
  
  Solution:
  
  
  Review Query Design: Check the design of the query in the Query Designer. Ensure that you are not trying to combine two incompatible structures. If necessary, redesign the query to use a single structure or ensure that the structures are compatible.
  
  
  Use a Single InfoProvider: If possible, modify the query to pull data from a single InfoProvider that contains all the necessary data. This may involve creating a new InfoProvider that consolidates the required data.
  
  
  Check for Compatibility: Ensure that the characteristics and key figures used in the query are compatible with each other. This may involve checking the data model and relationships between the InfoProviders.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on query design and limitations regarding the use of multiple structures.
  
  
  Testing: After making changes, test the query to ensure that it runs without errors and returns the expected results.
