• What is the cause and solution for SAP error message RSM848 - New aggregation for aggregate &(&) for InfoCube & started ?

  The SAP error message RSM848 indicates that a new aggregation for an InfoCube has been initiated. This message typically occurs during the process of data loading or when performing certain operations on an InfoCube in SAP BW (Business Warehouse). Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  New Aggregation Process: The message indicates that a new aggregation process is being started for the specified InfoCube. This can happen when:
  
  Data is being loaded into the InfoCube.
  The InfoCube has been modified (e.g., new characteristics or key figures added).
  The InfoCube is being optimized or restructured.
  
  
  
  Data Volume: If the InfoCube contains a large volume of data, the aggregation process can take a significant amount of time, leading to this message being displayed.
  
  
  System Performance: If the system is under heavy load or if there are performance issues, the aggregation process may be delayed or interrupted.
  
  
  Solution:
  
  
  Monitor the Aggregation Process: Check the status of the aggregation process in the SAP BW system. You can do this using transaction codes like RSA1 (Data Warehousing Workbench) or RSMO (Manage Aggregates).
  
  
  Check for Errors: Look for any error messages or logs that may indicate why the aggregation is taking longer than expected. Use transaction SM37 to check for job logs related to the aggregation.
  
  
  Optimize the InfoCube: If the InfoCube is frequently causing aggregation issues, consider optimizing it by:
  
  Reducing the amount of data stored (e.g., archiving old data).
  Reviewing the design of the InfoCube to ensure it meets current reporting needs without unnecessary complexity.
  
  
  
  Increase System Resources: If the system is under heavy load, consider increasing the resources (CPU, memory) allocated to the SAP BW system to improve performance.
  
  
  Schedule Aggregation Jobs: If possible, schedule aggregation jobs during off-peak hours to minimize the impact on system performance.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes that may address specific issues related to aggregation for your version of SAP BW.
