  The SAP error message ESH_OM_OBJ_MODEL_ODP045 indicates that there is an issue with the configuration of a DataSource in the context of the SAP Enterprise Search (ESH) or the SAP HANA platform. Specifically, the error message states that there are "no fields with path to other nodes allowed," which typically means that the DataSource is trying to reference fields or nodes that are not permitted in the current context.
  Cause:
  
  DataSource Configuration: The DataSource may be incorrectly configured to include fields that reference other nodes or tables, which is not allowed in the context of the ODP (Operational Data Provisioning) framework.
  Hierarchy Issues: If the DataSource is based on a hierarchical structure, it may be trying to access fields that are not directly related or are not part of the same node.
  Incompatible Field Types: The fields being referenced may not be compatible with the expected structure of the DataSource.
  
  Solution:
  
  Review DataSource Configuration: Check the configuration of the DataSource in the SAP system. Ensure that it only includes fields that are allowed and does not reference other nodes or tables.
  Adjust Field Selection: Modify the field selection in the DataSource to remove any fields that are causing the issue. Ensure that all fields are directly related to the main node of the DataSource.
  Check Hierarchical Relationships: If the DataSource is based on a hierarchy, ensure that the relationships between nodes are correctly defined and that the fields being accessed are valid within that hierarchy.
  Consult Documentation: Refer to the SAP documentation for ODP and DataSource configuration to ensure compliance with the required structure and rules.
  Testing: After making changes, test the DataSource to ensure that it works correctly without triggering the error message.
