• Message class: ESH_OM_OBJ_MODEL_RP2 - Object Model Repository (2)

• Message number: 863

• Message text: Not all key fields of node &2 are referenced in the nodes response fields

What causes this issue?

Node &v1& (which is the root node the object type) has a response field
named &v2& which itself references a node field that is based on field
&v4& of table &v3&. This indicates that the object type is prepared to
provide files to the search ui as for example a thumbnail.
Then all key fields of the node must be referenced in response fields of
the node.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Reference all key fields of node &v1& in response fields of the node or

• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_RP2863 - Not all key fields of node &2 are referenced in the nodes response fields ?

  The SAP error message ESH_OM_OBJ_MODEL_RP2863 indicates that not all key fields of a specified node are referenced in the response fields of that node. This error typically arises in the context of SAP's Enterprise Search or Object Model, where the data structure and its key fields must be properly defined and referenced.
  Cause:
  
  Incomplete Mapping: The key fields of the node are not fully mapped to the response fields. This can happen if the data model is not correctly defined or if there are changes in the underlying data structure that have not been reflected in the response configuration.
  Configuration Issues: There may be issues in the configuration of the search model or the object model that lead to discrepancies between the expected key fields and the actual response fields.
  Data Model Changes: If there have been recent changes to the data model (e.g., adding or removing key fields), the response fields may not have been updated accordingly.
  
  Solution:
  
  Check Node Configuration: Review the configuration of the node in the object model. Ensure that all key fields are correctly defined and that they are included in the response fields.
  Update Response Fields: If key fields have been added or modified, update the response fields to include all necessary key fields. This may involve modifying the data retrieval logic or the mapping of fields.
  Validate Data Model: Ensure that the data model is consistent and that all key fields are properly referenced. You may need to regenerate or refresh the object model to reflect any changes.
  Testing: After making changes, test the search functionality to ensure that the error is resolved and that the expected data is returned.
