Thank you for the response.
We are on PC 10 SP13. With some hit and trial, I am able to use report AUT_REP10 in ABAP report scenario. I am not using any variant instead I defined the values in my Business Rule like screen Number, Date and Table. I am able to use this report now in BR. I scheduled the BR and able to display the expected result in job results.
Best Regards,
Abhishek
