• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_REP142 - From-node &1/&2 does not exist ?

  The SAP error message ESH_OM_OBJ_MODEL_REP142 indicates that there is an issue with the object model in the Enterprise Search (ESH) framework. Specifically, the error message states that a "From-node" identified by the parameters &1 and &2 does not exist. This typically means that the system is trying to reference an object or node in the search model that has not been defined or has been deleted.
  Causes:
  
  Missing Object Definition: The object model may not have been properly defined, or the specific node that the system is trying to access has not been created.
  Deleted or Inactive Nodes: The node may have been deleted or marked as inactive in the object model.
  Configuration Issues: There may be configuration issues in the Enterprise Search settings or the object model itself.
  Transport Issues: If the object model was transported from another system, there may have been issues during the transport process that led to missing nodes.
  
  Solutions:
  
  
  Check Object Model Configuration:
  
  Go to the ESH configuration in the SAP system and verify that the object model is correctly defined.
  Ensure that the node referenced by &1 and &2 exists in the object model.
  
  
  
  Recreate Missing Nodes:
  
  If the node is missing, you may need to recreate it in the object model. This can typically be done through the ESH configuration transaction.
  
  
  
  Activate the Object Model:
  
  If the object model or specific nodes are inactive, activate them to ensure they are available for use.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, check the transport logs for any errors or warnings related to the object model.
  Ensure that all necessary objects were included in the transport request.
  
  
  
  Debugging:
  
  If you have access to debugging tools, you can trace the execution to see where the error is being triggered and gather more context about the missing node.
  
  
  
  Consult Documentation:
