• What is the cause and solution for SAP error message /BOBF/CONF298 - Table type &1 of alt.key. &2 shall not have unique primary/secondary keys ?

  The SAP error message /BOBF/CONF298 indicates that there is an issue with the configuration of a Business Object Framework (BOF) in SAP, specifically related to the uniqueness of keys in a table type. This error typically arises when the system detects that the specified table type for an alternative key does not have unique primary or secondary keys defined, which is a requirement for the proper functioning of the Business Object.
  Cause:
  
  Non-Unique Keys: The table type defined for the alternative key does not have unique primary or secondary keys. This means that the system cannot guarantee that each entry in the table can be uniquely identified.
  Configuration Error: There may be a misconfiguration in the Business Object definition where the alternative key is set up incorrectly.
  Data Model Issues: The underlying data model may not be designed to support the uniqueness constraints required for the alternative key.
  
  Solution:
  
  
  Check Table Type Definition: Review the definition of the table type associated with the alternative key. Ensure that it has a unique primary key or secondary key defined.
  
  Go to the Data Dictionary (SE11) and check the structure of the table type.
  Ensure that the fields defined as keys are indeed unique.
  
  
  
  Modify Business Object Configuration: If the table type is correct, check the configuration of the Business Object in the Business Object Framework (BOF).
  
  Use transaction code /BOBF/CONF to access the configuration of the Business Object.
  Verify the settings for the alternative key and ensure that it is correctly configured to reference a table type with unique keys.
  
  
  
  Adjust Data Model: If necessary, consider adjusting the data model to ensure that the alternative key can be uniquely identified. This may involve adding additional fields to the key definition or changing the structure of the data.
  
  
  Testing: After making the necessary changes, test the Business Object to ensure that the error no longer occurs and that the alternative key functions as expected.
