• What is the cause and solution for SAP error message RSDD025 - Aggregate contains an unknown hierarchy for & ?

  The SAP error message RSDD025 indicates that there is an issue with an aggregate in the SAP BW (Business Warehouse) system, specifically that it contains an unknown hierarchy for a characteristic. This typically occurs when the aggregate is trying to reference a hierarchy that is not defined or is not available in the system.
  Cause:
  
  Missing Hierarchy: The hierarchy that the aggregate is trying to use is not defined in the InfoObject.
  Incorrect Hierarchy Assignment: The hierarchy might be assigned incorrectly or is not active.
  Data Model Changes: Changes in the data model, such as modifications to InfoObjects or hierarchies, can lead to this error.
  Transport Issues: If the hierarchy was transported from another system and the transport did not include the hierarchy definition, this error can occur.
  
  Solution:
  
  
  Check Hierarchy Definition:
  
  Go to the InfoObject maintenance (transaction RSD1) and check if the hierarchy is defined for the characteristic in question.
  Ensure that the hierarchy is active and correctly assigned.
  
  
  
  Rebuild the Aggregate:
  
  If the hierarchy is defined but the error persists, you may need to rebuild the aggregate. This can be done by:
  
  Deleting the existing aggregate.
  Recreating it to ensure it picks up the current state of the InfoObjects and hierarchies.
  
  
  
  
  
  Check Transport Requests:
  
  If the hierarchy was recently transported, ensure that the transport request included all necessary objects. You may need to re-transport the hierarchy if it was missed.
  
  
  
  Activate Hierarchies:
  
  If the hierarchy is inactive, activate it in the hierarchy maintenance (transaction RSH1).
  
  
  
  Check for Data Consistency:
  
  Run consistency checks in the BW system to ensure that all objects are correctly defined and there are no inconsistencies.
  
  
  
  Review Documentation:
  
  Check SAP Notes and documentation for any specific issues related to the version of SAP BW you are using.
