  The SAP error message NRSCNV054 indicates that high cardinality is already disabled for a specific InfoObject in the context of SAP BW (Business Warehouse) or SAP HANA. High cardinality refers to the situation where an InfoObject has a large number of unique values, which can lead to performance issues in certain scenarios.
  Cause:
  The error occurs when you attempt to enable high cardinality for an InfoObject that has already been set to have high cardinality disabled. This can happen during data modeling or when trying to change the properties of the InfoObject in the SAP BW system.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check InfoObject Settings:
  
  Go to the InfoObject maintenance transaction (e.g., RSA1 in SAP BW).
