• What is the cause and solution for SAP error message RSDD112 - Aggregate &1(&2) is being filled ?

  The SAP error message RSDD112, which states "Aggregate &1(&2) is being filled," typically occurs in the context of SAP BW (Business Warehouse) when you are trying to access or query an aggregate that is currently being filled or updated. This can happen during data loading processes or when aggregates are being recalculated.
  Cause:
  
  Ongoing Data Load: The aggregate is currently being filled with data, which means that it is locked for reading until the process is complete.
  Long Running Processes: If the data load or aggregate filling process takes a long time, it can lead to this error if users attempt to access the aggregate during this period.
  Locking Mechanism: SAP BW uses a locking mechanism to ensure data integrity. When an aggregate is being filled, it is locked to prevent inconsistencies.
  
  Solution:
  
  Wait for Completion: The simplest solution is to wait until the data load or aggregate filling process is complete. You can check the status of the data load in the Data Warehousing Workbench or the process chain monitor.
  Monitor Process Chains: Use transaction codes like RSPC to monitor the status of process chains and see if the aggregate filling process is still running.
  Check for Long-Running Jobs: If the filling process is taking too long, investigate the job logs to identify any issues that may be causing delays.
  Schedule Off-Peak Loads: If possible, schedule data loads and aggregate filling during off-peak hours to minimize the impact on users querying the data.
  Review Aggregate Design: If this issue occurs frequently, consider reviewing the design of your aggregates. You may need to optimize the data model or the way aggregates are built to reduce the time taken for filling.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSPC (Process Chain), and SM37 (Job Monitoring) to monitor and manage data loads and aggregates.
  SAP Notes: Check SAP Notes for any known issues or patches related to aggregate filling and performance.
  Performance Tuning: Consider performance tuning strategies for your BW system, including optimizing data loads, indexing, and aggregate design.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or BW team for further investigation.
