How To Fix ESH_OM_OBJ_MODEL_REP390 - Start-node of navigation path differs from from-node of first step

ESH_OM_OBJ_MODEL_REP390 - Overview

• Message type: E = Error

• Message class: ESH_OM_OBJ_MODEL_REP - Object Model Repository

• Message number: 390

• Message text: Start-node of navigation path differs from from-node of first step

What causes this issue?

A navigation path links the two nodes:
Start-node: Node where the path begins
End-node: Node where the path ends
It also consists of a sequence of steps.
A navigation path step links the two nodes.
From-node: Node where the step starts
To-node: Node where the step ends
The start-node of the path must be the same node as the from-node of the
first step.
The end-node of the path must be the same node as the to-node of the
last step.
This is not the case.

• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_REP390 - Start-node of navigation path differs from from-node of first step ?

  The SAP error message ESH_OM_OBJ_MODEL_REP390 indicates that there is a mismatch in the navigation path within the Enterprise Search (ESH) framework. Specifically, it suggests that the start node of the navigation path does not match the from-node of the first step in the navigation path. This can occur in scenarios where the configuration of the search model or the navigation paths has inconsistencies.
  
  Cause:
  
  
  Configuration Issues: The navigation path may be incorrectly configured in the ESH model. This can happen if the start node is not properly defined or if there are changes in the underlying data model that have not been reflected in the navigation path.
  Data Model Changes: If there have been changes to the data model (e.g., changes in the underlying database tables or structures), the navigation paths may not align with the new structure.
  Inconsistent Object Types: The object types defined in the navigation path may not correspond correctly to
