• What is the cause and solution for SAP error message RSDD019 - Select at least one suitable aggregate ?

  The SAP error message RSDD019, which states "Select at least one suitable aggregate," typically occurs in the context of SAP BW (Business Warehouse) when a query is executed without a suitable aggregate being selected. This can happen when the system cannot find an appropriate aggregate to optimize the query performance, leading to the error.
  Cause:
  
  No Aggregates Defined: The InfoCube or the query may not have any aggregates defined, or the existing aggregates do not meet the criteria for the query being executed.
  Incompatible Aggregates: The aggregates that are defined may not be compatible with the characteristics or key figures being queried.
  Query Design Issues: The query may be designed in such a way that it does not align with the available aggregates.
  Data Model Changes: Changes in the data model, such as adding or removing characteristics or key figures, may lead to the existing aggregates becoming unsuitable.
  
  Solution:
  
  Check Aggregates: Go to the InfoCube in the SAP BW system and check if there are any aggregates defined. If not, you may need to create new aggregates that suit your query requirements.
  Create or Adjust Aggregates: If aggregates exist but are not suitable, consider creating new aggregates or adjusting the existing ones to include the necessary characteristics and key figures.
  Query Design Review: Review the query design to ensure that it aligns with the aggregates. Make sure that the characteristics and key figures used in the query are included in the aggregates.
  Rebuild Aggregates: If the aggregates are outdated or not functioning correctly, consider rebuilding them to ensure they are optimized for the current data model.
  Check for Data: Ensure that there is data available in the InfoCube that matches the criteria of the query. If there is no data, the aggregates may not be applicable.
  
  Related Information:
