• What is the cause and solution for SAP error message RSDD735 - Parameter &1 is set: Fragmented aggregate structure deactivated ?

  The SAP error message RSDD735, which states "Parameter &1 is set: Fragmented aggregate structure deactivated," typically occurs in the context of SAP BW (Business Warehouse) when dealing with aggregates in InfoCubes. This message indicates that the system has detected a fragmented aggregate structure, which can lead to performance issues or inconsistencies in data retrieval.
  Cause:
  The error is caused by the configuration of aggregates in the InfoCube. Specifically, it occurs when:
  
  The aggregate structure is fragmented, meaning that the data is not optimally organized for efficient access.
  The system has a parameter set that deactivates the use of fragmented aggregates to ensure data integrity and performance.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check Aggregate Settings:
  
  Go to the InfoCube in the Data Warehousing Workbench (transaction RSA1).
  Check the aggregate settings and see if there are any fragmented aggregates.
  
  
  
  Rebuild Aggregates:
  
  If you find that the aggregates are fragmented, you may need to rebuild them. This can be done by:
  
  Deleting the existing aggregates and then re-creating them.
  Using the "Manage Aggregates" option to optimize the structure.
  
  
  
  
  
  Adjust Parameters:
  
  Review the settings for the parameter that is causing the deactivation of fragmented aggregates. This may involve changing the configuration in the BW system settings.
  You can check the relevant parameters in transaction RSCUSTV10 or RSCUSTA1.
  
  
  
  Monitor Performance:
  
  After making changes, monitor the performance of the InfoCube and the aggregates to ensure that the issue is resolved and that data retrieval is efficient.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to aggregates and performance tuning in BW for additional guidance.
  
  
  
  Related Information:
  
  Transaction Codes: RSA1 (Data Warehousing Workbench), RSCUSTV10 (Customizing Parameters), RSCUSTA1 (Customizing for BW).
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or patches related to this error.
  Performance Tuning: Consider general performance tuning practices for BW, such as optimizing data loads, indexing, and partitioning.
  
  By following these steps, you should be able to address the RSDD735 error and improve the performance of your SAP BW aggregates.
