  The SAP error message RSDD146, which states "Aggregate &1: Repair indexes," typically occurs in the context of SAP BW (Business Warehouse) when there are inconsistencies or issues with the aggregate indexes. This can happen due to various reasons, such as data load failures, changes in the underlying data model, or issues during the aggregation process.
  Cause:
  
  Data Load Issues: If there were problems during data loading (e.g., incomplete loads, errors in data extraction), it can lead to inconsistencies in the aggregates.
  Changes in Data Model: If there have been changes to the InfoObjects or the structure of the aggregates, the existing indexes may become invalid.
  System Errors: Any system-related issues or interruptions during the aggregation process can also lead to this error.
  
  Solution:
  To resolve the RSDD146 error, you can follow these steps:
  
  
  Repair Indexes:
  
  Go to the transaction code RSA1 (Data Warehousing Workbench).
  Navigate to the InfoProvider that contains the aggregate.
  Right-click on the aggregate and select the option to "Repair Indexes" or "Rebuild Indexes."
  This process will rebuild the indexes for the specified aggregate.
  
  
  
  Check for Data Load Errors:
  
  Review the data load logs to identify any errors that may have occurred during the last data load.
  Resolve any issues found and re-run the data load if necessary.
  
  
  
  Rebuild Aggregates:
  
  If repairing the indexes does not resolve the issue, consider rebuilding the aggregate completely.
  This can be done by deleting the existing aggregate and creating a new one.
  
  
  
  Check for Changes in Data Model:
  
  Ensure that any changes made to the InfoObjects or the structure of the aggregates are properly reflected in the aggregates.
  If necessary, adjust the aggregates to align with the current data model.
  
  
  
  Run Consistency Checks:
  
  Use the transaction code RSBAS000 to run consistency checks on the aggregates and InfoProviders to identify any further issues.
