• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_REP601 - Relation &1 has no field mapping and no fixed values ?

  The SAP error message ESH_OM_OBJ_MODEL_REP601 indicates that there is an issue with the configuration of a relation in the Enterprise Search (ES) Object Model. Specifically, the message states that the relation identified by &1 does not have any field mapping or fixed values defined. This can prevent the system from properly processing or utilizing the relation in search queries.
  Cause
  The error can occur due to several reasons:
  
  Missing Configuration: The relation may not have been properly configured in the Object Model. This includes not defining field mappings or fixed values that are necessary for the relation to function correctly.
  Changes in Data Model: If there have been changes to the underlying data model or the structure of the objects involved, the existing relations may no longer be valid or may require updates.
  Transport Issues: If the configuration was transported from one system to another (e.g., from development to production), there may have been issues during the transport that resulted in missing configurations.
  
  Solution
  To resolve this error, you can take the following steps:
  
  
  Check Relation Configuration:
  
  Go to the SAP GUI and navigate to the relevant transaction for managing the Object Model (e.g., Esh_om).
  Locate the relation identified by &1 and check its configuration.
  Ensure that field mappings are defined correctly and that any necessary fixed values are specified.
  
  
  
  Define Field Mappings:
  
  If field mappings are missing, you will need to define them. This involves mapping fields from the source object to the target object in the relation.
  Make sure that the fields you are mapping are compatible and exist in both objects.
  
  
  
  Add Fixed Values:
  
  If the relation requires fixed values, ensure that these are defined. Fixed values can be used to filter or restrict the data that is returned in search results.
  
  
  
  Test the Configuration:
  
  After making the necessary changes, test the configuration to ensure that the relation works as expected and that the error message no longer appears.
  
  
  
  Transport Configuration:
  
  If the issue arose after a transport, verify that all necessary objects and configurations were included in the transport request. If not, you may need to re-transport the missing configurations.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the Enterprise Search Object Model for additional guidance on configuring relations and resolving related issues.
