• What is the cause and solution for SAP error message /FTI/INTERNAL_ERROR048 - BCO definition ambiguous.Key field parameter &1 occurs multiple times ?

  The SAP error message /FTI/INTERNAL_ERROR048 BCO definition ambiguous. Key field parameter &1 occurs multiple times typically indicates that there is an issue with the Business Configuration Object (BCO) definition in the SAP system. This error arises when a key field parameter is defined multiple times within the same context, leading to ambiguity in the system's understanding of which parameter to use.
  Cause:
  
  Duplicate Key Field Parameters: The most common cause of this error is that the same key field parameter is defined more than once in the BCO configuration. This can happen due to incorrect configuration or merging of different configurations that have overlapping definitions.
  Incorrect Data Model: If the data model has been altered or if there are inconsistencies in the way the BCOs are defined, it can lead to this error.
  Transport Issues: If BCO definitions were transported from one system to another, there might be conflicts or duplicates that were not resolved.
  
  Solution:
  
  Review BCO Definitions: Check the BCO definitions in the SAP system to identify where the key field parameter is defined multiple times. You can do this by navigating to the relevant configuration area in the SAP GUI.
  Remove Duplicates: Once you identify the duplicate definitions, remove or consolidate them to ensure that each key field parameter is defined only once.
  Check for Transport Issues: If the issue arose after a transport, review the transport logs and ensure that the BCO definitions are consistent across systems.
  Consult Documentation: Refer to SAP documentation or notes related to the specific BCO you are working with to ensure that you are following the correct configuration guidelines.
  Testing: After making changes, test the configuration to ensure that the error is resolved and that the system behaves as expected.
