• What is the cause and solution for SAP error message RSAOLTP458 - DataSource & is of Type &2, but contains hierarchy information ?

  The SAP error message RSAOLTP458 indicates that there is an issue with a DataSource that is expected to be of a certain type but contains hierarchy information that is not compatible with that type. This error typically arises in the context of SAP BW (Business Warehouse) when working with DataSources that are expected to handle certain types of data structures.
  Cause:
  
  DataSource Type Mismatch: The DataSource is defined as a certain type (e.g., a flat structure) but contains hierarchy information that is typically associated with a different type (e.g., a hierarchy-enabled structure).
  Incorrect Configuration: The DataSource may have been incorrectly configured or set up to include hierarchy data when it should not.
  Data Extraction Issues: The underlying data source (like an SAP ERP system) may have been modified, leading to discrepancies in the expected data structure.
  
  Solution:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system and verify its configuration. Ensure that it is set up correctly for the type of data it is supposed to handle.
  If the DataSource is supposed to handle hierarchies, ensure that it is defined as a hierarchy-enabled DataSource.
  
  
  
  Adjust DataSource Type:
  
  If the DataSource is incorrectly defined, you may need to change its type to accommodate the hierarchy information. This can involve re-defining the DataSource in the SAP BW system.
  
  
  
  Review Hierarchy Settings:
  
  If the DataSource is intended to include hierarchy information, ensure that the hierarchy settings are correctly configured in the source system (e.g., SAP ERP).
  Check if the hierarchy data is being extracted correctly and that it aligns with the DataSource's expected structure.
  
  
  
  Re-Extract Data:
  
  After making the necessary adjustments, you may need to re-extract the data from the source system to ensure that the DataSource is populated correctly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource and its expected configuration. This can provide insights into common issues and their resolutions.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling DataSources with hierarchy information.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Testing: After making changes, conduct thorough testing to ensure that the DataSource is functioning as expected and that the data is being extracted and loaded correctly into the BW system.
  
  By following these steps, you should be able to resolve the RSAOLTP458 error and ensure that your DataSource is correctly configured to handle the data it is intended to process.
