Smart SAP Assistant

• What is the cause and solution for SAP error message RS_B4HPREP084 - Write-optimized DataStore Object &1 has DAP and is used for reporting ?

  The SAP error message RS_B4HPREP084 indicates that a Write-Optimized DataStore Object (DSO) is being used for reporting, which is not allowed when the DSO has Data Access Policies (DAP) applied to it. This situation typically arises in the context of SAP BW (Business Warehouse) or SAP BW/4HANA environments.
  Cause:
  
  Write-Optimized DSO: A Write-Optimized DSO is designed for high-speed data loading and is not intended for reporting purposes. It is optimized for data ingestion rather than for querying.
  Data Access Policies (DAP): DAPs are used to control access to data based on certain conditions or rules. When a DAP is applied to a DSO, it restricts how data can be accessed and reported on.
  Incompatibility: The combination of a Write-Optimized DSO and DAPs creates a conflict because the system does not support reporting on data that is subject to access restrictions in a Write-Optimized DSO.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Change the DSO Type:
  
  If reporting is required on the data, consider converting the Write-Optimized DSO to a standard DSO or an InfoCube. This will allow you to use the DAPs while also enabling reporting capabilities.
  
  
  
  Remove DAPs:
  
  If the DAPs are not essential for your reporting needs, you can remove them from the DSO. However, this may not be advisable if data access control is a requirement for your organization.
  
  
  
  Use a Different Reporting Layer:
  
  If you need to keep the Write-Optimized DSO and the DAPs, consider creating a view or a composite provider that can aggregate data from the Write-Optimized DSO and present it in a way that is suitable for reporting.
  
  
  
  Consult Documentation:
  
  Review SAP documentation for best practices regarding the use of Write-Optimized DSOs and DAPs. This can provide insights into how to structure your data models effectively.
  
  
  
  Related Information:
