• What is the cause and solution for SAP error message RSDD802 - Aggregate &1 is empty ?

  The SAP error message RSDD802, which states "Aggregate &1 is empty," typically occurs in the context of SAP BW (Business Warehouse) when you are trying to access or use an aggregate that has not been populated with data. This can happen for various reasons, and understanding the cause and finding a solution is essential for resolving the issue.
  Causes:
  
  
  No Data Loaded: The most common reason for this error is that the aggregate has not been populated with any data. This can happen if the InfoProvider (e.g., InfoCube) that the aggregate is based on has not had data loaded into it.
  
  
  Data Deletion: Data might have been deleted from the underlying InfoProvider, leading to an empty aggregate.
  
  
  Incorrect Aggregation Settings: The settings for the aggregate might be incorrect, leading to it not being populated as expected.
  
  
  Data Source Issues: There may be issues with the data source or the data extraction process that prevent data from being loaded into the aggregate.
  
  
  Change in Data Model: Changes in the data model or InfoObjects used in the aggregate can lead to inconsistencies.
  
  
  Solutions:
  
  
  Check Data Loading: Verify that data has been successfully loaded into the underlying InfoProvider. You can do this by checking the data in the InfoCube or DataStore Object (DSO) that the aggregate is based on.
  
  
  Rebuild the Aggregate: If the aggregate is empty, you may need to rebuild it. This can be done by:
  
  Going to the aggregate maintenance transaction (e.g., RSA1).
  Selecting the aggregate and choosing the option to rebuild or reinitialize it.
  
  
  
  Check Data Source: Ensure that the data source is functioning correctly and that there are no issues with the extraction process. Check for any errors in the data loading process.
  
  
  Review Aggregation Settings: Check the settings of the aggregate to ensure they are configured correctly. This includes verifying the key figures and characteristics included in the aggregate.
  
  
  Monitor Data Deletion: If data has been deleted, consider whether this was intentional or if it needs to be restored. You may need to reload data if it was deleted inadvertently.
  
  
  Check for Changes in Data Model: If there have been recent changes to the data model, ensure that the aggregate is still valid and that all necessary InfoObjects are included.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to manage aggregates and check data loading status.
  Logs and Monitoring: Check the process chains and logs for any errors or warnings related to data loading.
  SAP Notes: Look for relevant SAP Notes that may address specific issues related to aggregates and data loading.
  
  By following these steps, you should be able to identify the cause of the RSDD802 error and implement a solution to resolve it.
