Hello Swati,
You are probably unable to view the legacy rules/rule scripts under Legacy Automated Monitoring in NWBC correct?
Please, check the following SAP note:
1582723 - Predelivered business Rules not provided in GRC-PC 10.0
If it does not work, you can try the following way:
1. Go to client 000
2. SPRO
3. Governance, Risk and Compliance
4. Process Control
5. Legacy Automated Monitoring
6. Automated Testing and Monitoring
7. Transport Master Data
8. Transport Rule Criteria
Check whether there are rule scripts there or not.
Thank you,
Fernando
