This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to roll up data from a lower level of granularity to a higher level in the data model.
  Cause:
  
  No Data in Aggregates: The most common cause of this error is that the aggregates for the InfoCube have not been filled with data. This can happen if the data loading process has not been executed successfully or if the aggregates were never created or activated.
  Incorrect Configuration: There may be issues with the configuration of the InfoCube or the aggregates, such as incorrect settings or missing data sources.
  Data Load Issues: If there were issues during the data load process (e.g., errors in the data extraction, transformation, or loading), it could result in empty aggregates.
  Data Deletion: If data was deleted from the InfoCube or aggregates, it could lead to this error when attempting to perform a rollup.
  
  Solution:
  
  Check Data Load: Ensure that the data load process for the InfoCube has been executed successfully. You can check the data loading logs for any errors or warnings.
  Fill Aggregates: If the aggregates are empty, you need to fill them. This can be done by executing the data load process again or by manually filling the aggregates using the appropriate transaction (e.g., using the RSBATCH transaction for batch processing).
  Check Aggregate Settings: Verify the settings for the aggregates in the InfoCube. Ensure that they are correctly configured and activated.
  Rebuild Aggregates: If necessary, you can rebuild the aggregates. This can be done by deleting the existing aggregates and then re-creating them.
  Monitor Data Deletion: If data was deleted, ensure that the necessary data is reloaded into the InfoCube and aggregates.
