• What is the cause and solution for SAP error message SADL_GW_DT_SB_UI202 - Root has parent view ?

  The SAP error message "SADL_GW_DT_SB_UI202 Root has parent view" typically occurs in the context of SAP Gateway and the SAP Data Access Layer (SADL). This error indicates that there is an issue with the way the data model is defined, particularly in relation to the parent-child relationships between views in the SADL framework.
  Cause:
  
  Model Definition Issues: The error often arises when there is a misconfiguration in the data model, particularly when a root view is incorrectly defined to have a parent view. In SADL, a root view should not have a parent view.
  Incorrect Annotations: The annotations in the CDS (Core Data Services) views may not be correctly set up, leading to confusion in the hierarchy of views.
  View Relationships: If the relationships between the views are not properly established, it can lead to this error.
  
  Solution:
  
  Check CDS View Definitions: Review the definitions of your CDS views to ensure that the root view does not have a parent view. The root view should be defined independently.
  Review Annotations: Ensure that the annotations in your CDS views are correctly defined. Pay special attention to the @UI and @OData annotations that define the relationships and properties of the views.
  Adjust View Hierarchies: If you have defined a hierarchy of views, make sure that the relationships are correctly established. The root view should not reference any parent view.
  Rebuild the Model: If necessary, you may need to rebuild the data model or regenerate the OData service to ensure that the changes take effect.
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as some issues may be resolved in newer versions.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for SADL and CDS views for detailed guidelines on how to define views and their relationships.
  SAP Community: Engage with the SAP Community forums where other users may have encountered similar issues and can provide insights or solutions.
  Debugging Tools: Utilize SAP debugging tools to trace the execution and identify where the error is being triggered in the data model.
