• What is the cause and solution for SAP error message HP_TEST029 - Edge type &2 can not be deleted due to usage of its graph in &1 &3 ?

  The SAP error message HP_TEST029 indicates that you are trying to delete an Edge type (in this case, represented by &2) that cannot be deleted because it is currently being used in a graph (represented by &1) along with additional context provided by &3. This typically occurs in the context of SAP HANA Graph or similar data modeling scenarios where relationships (edges) between nodes (vertices) are defined.
  Cause:
  
  Existing Relationships: The edge type you are trying to delete is still in use by one or more graphs. This means that there are existing relationships or connections that rely on this edge type.
  Data Integrity: SAP enforces data integrity rules to prevent the deletion of elements that are still in use, which could lead to orphaned data or broken relationships.
  
  Solution:
  
  Identify Usage: First, identify where the edge type is being used. You can do this by querying the relevant graphs or checking the data model to see which graphs reference the edge type.
  Remove Dependencies: Before you can delete the edge type, you need to remove all dependencies. This may involve:
  
  Deleting or modifying the graphs that use this edge type.
  Removing any relationships that utilize this edge type.
  
  
  Delete Edge Type: Once all dependencies have been removed, you should be able to delete the edge type without encountering the error.
  Check for Other References: Ensure that there are no other references to the edge type in other parts of your data model or application.
  
  Related Information:
  
  Documentation: Refer to the SAP HANA documentation for more details on managing graph data and edge types.
  Transaction Codes: Familiarize yourself with relevant transaction codes or tools in SAP that allow you to manage graph structures.
