• What is the cause and solution for SAP error message RSRTS_CDS106 - Hierarchy binding entry &1: No hierarchy key component found ?

  The SAP error message RSRTS_CDS106 indicates that there is an issue with a hierarchy binding in a CDS (Core Data Services) view. Specifically, the error message states that there is no hierarchy key component found for the specified hierarchy binding entry. This typically occurs when the system is unable to find the necessary key components that define the hierarchy structure in the context of the CDS view.
  Cause:
  
  Missing Key Components: The hierarchy defined in the CDS view does not have the required key components. This can happen if the hierarchy is not properly defined or if the key fields are not included in the CDS view.
  Incorrect Hierarchy Definition: The hierarchy might be incorrectly defined in the underlying data model or the CDS view itself.
  Data Model Changes: If there have been recent changes to the data model (e.g., changes in the underlying tables or fields), it may lead to inconsistencies in the hierarchy definition.
  Transport Issues: If the CDS view or hierarchy was transported from one system to another, there might be missing dependencies or inconsistencies.
  
  Solution:
  
  Check Hierarchy Definition: Review the hierarchy definition in the CDS view. Ensure that all necessary key components are included and correctly defined.
  Update CDS View: If the hierarchy key components are missing, update the CDS view to include the required fields. Make sure that the fields used for the hierarchy are marked as key fields.
  Validate Data Model: Ensure that the underlying data model supports the hierarchy. Check if the tables and fields used in the hierarchy are correctly defined and accessible.
  Rebuild Hierarchy: If the hierarchy is corrupted or incorrectly defined, consider rebuilding it from scratch.
  Check Transport Requests: If the issue arose after a transport, check the transport requests to ensure that all necessary objects were included and correctly transported.
  Test in Development: Before making changes in the production environment, test the changes in a development or quality assurance environment to ensure that the issue is resolved.
