• What is the cause and solution for SAP error message RSM1521 - Displaying content of DataStore object table is not supported ?

  The SAP error message RSM1521, which states "Displaying content of DataStore object table is not supported," typically occurs when you attempt to view the contents of a DataStore Object (DSO) directly in the SAP BW (Business Warehouse) system. This error indicates that the system does not allow direct access to the underlying database table of a DSO for display purposes.
  Cause:
  
  Technical Limitation: The DSO is designed to store data in a specific format that is optimized for reporting and data processing. Directly accessing the underlying table is not supported due to the complexity of the data model and the potential for data integrity issues.
  Data Model Design: DSOs are meant to be accessed through queries or reports rather than through direct table access. This is part of the design philosophy of SAP BW to ensure data consistency and integrity.
  
  Solution:
  
  Use Queries: Instead of trying to display the contents of the DSO table directly, you should create and use queries in SAP BW. You can use tools like BEx Query Designer or Analysis for Office to create reports that pull data from the DSO.
  Data Preview: If you need to preview the data in the DSO, you can use the Data Warehousing Workbench (transaction RSA1) to view the data in a more structured way. Navigate to the DSO, and use the "Data Preview" option to see the data.
  Data Extraction: If you need to extract data for analysis, consider using the extraction capabilities of SAP BW to load the data into a different format or system where you can analyze it without direct table access.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSD1 (InfoObject Maintenance), and RSRT (Query Monitor) for working with BW objects.
  Documentation: Refer to SAP Help documentation for more details on working with DSOs and best practices for data modeling in SAP BW.
  SAP Notes: Check for any relevant SAP Notes that might provide additional context or updates regarding this error message.
  
  By following these guidelines, you should be able to work around the limitations imposed by the RSM1521 error and effectively access and analyze the data stored in your DataStore Objects.
