• What is the cause and solution for SAP error message NRSCNV160 - InfoObject &1 is already being used as a reference characteristic ?

  The SAP error message NRSCNV160 indicates that an InfoObject (characteristic) is already being used as a reference characteristic in a different context, which prevents you from using it in the current operation. This typically occurs during the process of creating or modifying InfoObjects, especially when dealing with characteristics in SAP BW (Business Warehouse) or SAP BW/4HANA.
  Cause:
  
  Reference Characteristic Usage: The InfoObject you are trying to use is already defined as a reference characteristic in another InfoObject or in a different context. This means that it cannot be reused in the way you are attempting.
  Data Model Conflicts: There may be conflicts in the data model where the same characteristic is being referenced multiple times, leading to this error.
  Inconsistent Metadata: The metadata definitions may not be consistent, causing the system to throw this error when it detects the conflict.
  
  Solution:
  
  Check Existing References: Review the InfoObject in question to see where it is being used as a reference characteristic. You can do this by navigating to the InfoObject maintenance transaction (e.g., RSA1) and checking the characteristics that reference it.
  Modify Usage: If you need to use the InfoObject in a different context, consider creating a new characteristic that can serve your purpose without conflicting with the existing reference.
  Remove Reference: If the reference is no longer needed, you can remove it from the other InfoObject. However, be cautious with this approach as it may affect other parts of your data model.
  Consult Documentation: Refer to SAP documentation or notes related to InfoObject management and reference characteristics for more detailed guidance.
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is impacting critical business processes.
