• What is the cause and solution for SAP error message RSM1485 - Re-aggregation of aggregate &1 refused, already rolled up to SID &2 ?

  The SAP error message RSM1485 indicates that there is an issue with the re-aggregation of an aggregate in the SAP BW (Business Warehouse) system. Specifically, it means that the system is refusing to re-aggregate the specified aggregate because it has already been rolled up to a specific SID (Surrogate ID).
  Cause:
  The error typically occurs in the following scenarios:
  
  Data Consistency: The aggregate has already been rolled up to a certain SID, which means that the data has been processed and stored in a way that prevents further changes to that aggregate.
  Data Load Issues: There may be ongoing data loads or updates that conflict with the re-aggregation process.
  Incorrect Process Flow: The re-aggregation process may be initiated at an inappropriate time, such as during a data load or when the system is in a state that does not allow for changes to aggregates.
  
  Solution:
  To resolve the RSM1485 error, you can take the following steps:
  
  
  Check Data Load Status: Ensure that there are no ongoing data loads or processes that might be locking the aggregate. If there are, wait for them to complete before attempting the re-aggregation again.
  
  
  Review Aggregate Settings: Verify the settings and configurations of the aggregate. Ensure that the aggregate is not set to a state that prevents re-aggregation.
  
  
  Roll Up Data: If necessary, you may need to roll up the data to the appropriate SID before attempting to re-aggregate. This can be done using the relevant transaction codes in SAP BW.
  
  
  Use Transaction RSCUSTV10: You can check the settings for aggregates in the transaction RSCUSTV10. This transaction allows you to view and modify the settings related to aggregates.
  
  
  Check for Locks: Use transaction SM12 to check for any locks on the aggregates that might be preventing the re-aggregation process.
  
  
  Consult SAP Notes: Look for any relevant SAP Notes that might address this specific error. SAP frequently updates its knowledge base with solutions for known issues.
  
  
  Contact SAP Support: If the issue persists after trying the above steps, consider reaching out to SAP support for further assistance.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSCUSTV10 (Customizing for Aggregates), and SM12 (Lock Entries).
  Documentation: Review SAP documentation related to aggregates and data loading processes in BW for best practices and troubleshooting tips.
  Performance Considerations: Understand the implications of aggregates on system performance and data retrieval, as improper handling can lead to performance degradation.
  
  By following these steps, you should be able to address the RSM1485 error and successfully manage your aggregates in SAP BW.
