• What is the cause and solution for SAP error message ESH_DP_MSG001 - Node &1 has multiple parent nodes (reduce to max. one parent node) ?

  The SAP error message ESH_DP_MSG001 indicates that a node in the Data Provisioning framework of SAP Enterprise Search (or similar applications) has been assigned multiple parent nodes. This situation violates the hierarchical structure expected in the data model, where each node should have a maximum of one parent node.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Data Model Configuration: The configuration of the data model may have been set up incorrectly, leading to a node being linked to multiple parent nodes.
  Data Import Issues: During the data import or provisioning process, there may have been inconsistencies or errors in the data that resulted in a node being associated with more than one parent.
  Manual Changes: If manual changes were made to the data structure or relationships without proper validation, it could lead to this error.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Identify the Node: Determine which node is causing the issue by checking the error message details. The node identifier (Node &1) will help you locate it in the system.
  
  
  Check Parent-Child Relationships:
  
  Navigate to the relevant configuration or data model in SAP.
  Review the parent-child relationships for the identified node.
  Ensure that each node has only one parent. If you find multiple parents, decide which relationship should be maintained.
  
  
  
  Modify the Data Model:
  
  If necessary, modify the data model to remove the additional parent relationships.
  This may involve deleting or reassigning parent nodes in the configuration.
  
  
  
  Data Consistency Check: After making changes, perform a consistency check on the data model to ensure that there are no further issues.
  
  
  Re-import Data: If the issue was caused by data import, consider re-importing the data after correcting the relationships.
  
  
  Testing: After making the necessary changes, test the data provisioning process to ensure that the error no longer occurs.
  
  
  Related Information:
  
  Documentation: Refer to the SAP Help Portal or specific documentation related to SAP Enterprise Search or Data Provisioning for detailed guidelines on configuring nodes and relationships.
