• What is the cause and solution for SAP error message RSDS503 - Data type of DataSource &1(&2) is not a hierarchy ?

  The SAP error message RSDS503 indicates that there is an issue with the data type of a DataSource in SAP BW (Business Warehouse). Specifically, it states that the DataSource you are trying to use is not a hierarchy, which can lead to problems when you are attempting to load or process data.
  Cause:
  
  DataSource Type: The DataSource you are working with is not defined as a hierarchy DataSource. Hierarchies are typically used for data that has a parent-child relationship, such as organizational structures or product categories.
  Incorrect Configuration: The DataSource may have been incorrectly configured or set up, leading to it being recognized as a standard DataSource rather than a hierarchy.
  Data Model Mismatch: The data model you are trying to use may expect a hierarchy DataSource, but the one you are using does not meet that requirement.
  
  Solution:
  
  Check DataSource Definition: Verify the definition of the DataSource in the SAP BW system. Ensure that it is set up as a hierarchy DataSource if that is what is required for your data model.
  
  Go to the DataSource in the Data Warehousing Workbench (transaction RSA1) and check its properties.
  
  
  Modify DataSource: If the DataSource is not set up correctly, you may need to create a new DataSource that is defined as a hierarchy or modify the existing one if possible.
  Use Correct DataSource: If you are using a DataSource that is not intended to be a hierarchy, switch to a DataSource that is designed for hierarchical data.
  Consult Documentation: Review SAP documentation or help resources for guidance on how to properly configure hierarchy DataSources.
  
  Related Information:
