• What is the cause and solution for SAP error message RSODP_ABAP_CDS006 - Hierarchy &1 of view &2 contains circular reference ?

  The SAP error message RSODP_ABAP_CDS006 indicates that there is a circular reference in the hierarchy of a Core Data Services (CDS) view. This typically occurs when a hierarchy is defined in such a way that it references itself, either directly or indirectly, creating a loop that cannot be resolved.
  Cause:
  
  Circular Reference: The hierarchy defined in the CDS view has a parent-child relationship that loops back on itself. For example, if a node in the hierarchy points to another node that eventually points back to the original node, this creates a circular reference.
  Incorrect Hierarchy Definition: The hierarchy might be incorrectly defined in the CDS view, leading to unintended relationships between nodes.
  Data Issues: Sometimes, the underlying data might have inconsistencies that lead to circular references when the hierarchy is constructed.
  
  Solution:
  
  Review Hierarchy Definition: Check the definition of the hierarchy in the CDS view. Ensure that the parent-child relationships are correctly defined and do not create loops.
  Modify the Hierarchy: If a circular reference is found, modify the hierarchy to eliminate the circular relationship. This may involve changing the way nodes are related or restructuring the hierarchy.
  Data Validation: Validate the underlying data to ensure that there are no entries that would cause circular references. This may involve checking for duplicate entries or incorrect parent-child relationships in the data.
  Testing: After making changes, test the CDS view to ensure that the error is resolved and that the hierarchy behaves as expected.
  
  Related Information:
