• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_REP144 - To-node &1/&2 does not exist ?

  The SAP error message ESH_OM_OBJ_MODEL_REP144 indicates that there is an issue with the object model in the Enterprise Search (ESH) framework. Specifically, the error message states that the "To-node &1/&2 does not exist," which suggests that the system is trying to reference a node in the object model that is not defined or has been deleted.
  Cause:
  
  Missing Object Model Node: The specified node in the object model does not exist. This could be due to a configuration issue or a deletion of the node.
  Incorrect Configuration: The object model might not be properly configured, leading to references to non-existent nodes.
  Transport Issues: If the object model was transported from one system to another, there might have been issues during the transport process that led to missing nodes.
  Data Consistency Issues: There may be inconsistencies in the data that the object model relies on, leading to references to non-existent nodes.
  
  Solution:
  
  
  Check Object Model Configuration:
  
  Go to the ESH configuration in the SAP system and verify the object model settings.
  Ensure that the nodes referenced in the error message are correctly defined in the object model.
  
  
  
  Recreate Missing Nodes:
  
  If you identify that the nodes are indeed missing, you may need to recreate them in the object model.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, check the transport logs to see if there were any errors during the transport of the object model.
  If necessary, re-transport the object model or manually recreate the missing nodes.
  
  
  
  Consistency Check:
  
  Run consistency checks for the object model to identify and resolve any inconsistencies.
  Use transaction codes like SE11 or SE80 to check the definitions of the object model.
