  The SAP error message NRSCNV422 indicates that there is an attempt to delete a rule that is defined on an Advanced DataStore Object (aDSO). This error typically arises in the context of data modeling or data transformation processes within SAP BW/4HANA or SAP BW on HANA environments.
  Cause:
  The primary cause of this error is that the rule you are trying to delete is actively being used in the context of an aDSO. In SAP BW, rules are often associated with data transformation processes, and if a rule is linked to an aDSO, it cannot be deleted until it is removed from that association.

  Delete the Rule: Once the rule is no longer associated with the aDSO, you should be able to delete it without encountering the NRSCNV422 error.
  
  
  Check for Dependencies: Ensure that there are no other dependencies or references to the rule in other transformations or processes.
  
  
  Transport Changes: If you are working in a development environment, remember to transport your changes to the appropriate environments (e.g., QA, Production) after making the necessary adjustments.
