• What is the cause and solution for SAP error message RSR_EXPLAIN001 - No exc. aggr. in HANA/BWA for constant &1 as it is a temp. hier. join ?

  The SAP error message RSR_EXPLAIN001 indicates that there is no executable aggregation in HANA or BWA for a constant that is being used in a temporary hierarchy join. This error typically arises in the context of SAP BW (Business Warehouse) when working with queries that involve complex data models, especially when using HANA as the database.
  Cause:
  
  Temporary Hierarchy Join: The error suggests that the query is trying to use a temporary hierarchy join, but the system cannot find an executable aggregation for the specified constant. This can happen if the hierarchy is not properly defined or if the aggregation settings are not compatible with the query being executed.
  Data Model Issues: There may be issues with the underlying data model, such as missing or incorrectly defined characteristics, or the aggregation levels may not be set up correctly.
  Query Design: The query might be designed in a way that does not allow for proper aggregation due to the use of constants or specific filters that are not supported in the current context.
  
  Solution:
  
  Check Hierarchy Definition: Ensure that the temporary hierarchy is correctly defined and that all necessary characteristics are included. Verify that the hierarchy is active and properly configured in the InfoObject settings.
  Review Query Design: Analyze the query design in the Query Designer. Look for any constants or filters that may be causing the issue. Consider simplifying the query or removing unnecessary filters to see if that resolves the error.
  Aggregation Settings: Check the aggregation settings in the InfoProvider. Ensure that the aggregation levels are correctly defined and that they match the requirements of the query.
  Update Statistics: If you are using HANA, consider updating the statistics for the relevant tables. This can sometimes resolve issues related to query performance and execution.
  Test with Different Scenarios: Try running the query with different parameters or without the temporary hierarchy to see if the error persists. This can help isolate the cause of the issue.
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or updates related to this error message. There may be specific patches or updates that address known issues.
