• What is the cause and solution for SAP error message RSDD454 - Attribute &1 is not permitted in aggregate because char. supports RDA ?

  The SAP error message RSDD454 indicates that an attribute (characteristic) is not permitted in an aggregate because it supports RDA (Remote Data Access). This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to create or modify aggregates that include certain characteristics that are not compatible with the RDA settings.
  Cause:
  
  RDA Support: The characteristic in question is set to support RDA, which means it is designed to be accessed remotely and is not suitable for use in aggregates. RDA is often used for characteristics that are large or frequently updated, as it allows for more efficient data access.
  Aggregate Definition: When defining aggregates, SAP BW requires that all characteristics included in the aggregate must be compatible with the aggregate's structure and performance requirements. Characteristics that support RDA cannot be included in aggregates.
  
  Solution:
  
  
  Review Characteristic Settings: Check the settings of the characteristic that is causing the error. If it is set to support RDA and you do not need this feature, consider changing its settings to not support RDA.
  
  Go to the characteristic in the Data Warehousing Workbench (transaction RSA1).
  Navigate to the "Attributes" tab and check the "RDA" setting.
  If RDA is not necessary, you can disable it.
  
  
  
  Modify Aggregate Definition: If the characteristic must remain as RDA, you will need to modify your aggregate definition to exclude this characteristic. Review the aggregate and remove the incompatible characteristic from the definition.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on RDA and aggregate definitions. This can provide insights into best practices and potential impacts of changing settings.
  
  
  Testing: After making changes, test the aggregate to ensure it functions correctly without the RDA characteristic or with the modified settings.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context.
  Performance Considerations: Understand the implications of using RDA and how it affects performance and data retrieval in your BW environment.
  SAP Community: Engage with the SAP Community forums for discussions and solutions shared by other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the RSDD454 error and successfully manage your aggregates in SAP BW.
