  Review Aggregate Definition: Check the definition of the new aggregate. Ensure that it is designed to improve performance by including only the necessary dimensions and measures.
  Analyze Existing Aggregates: Look at the existing aggregates to understand their structure and performance. Determine if they can be optimized or if the new aggregate can be adjusted to provide a better performance benefit.
  Use the Aggregate Monitor: Utilize the Aggregate Monitor in SAP BW to analyze the performance of existing aggregates and see if they meet the requirements for your reporting needs.
  Adjust Settings: If applicable, adjust the settings of the new aggregate to ensure it is configured correctly. This may include changing the key figures, dimensions, or other parameters.
  Delete Unnecessary Aggregates: If there are aggregates that are no longer needed or are redundant, consider deleting them to simplify the aggregate structure.
