DevOps, CI/CD and Automation

Hello,
I am using .bat file to generate a report PDF output. I have done this many times in 6i but for 10G I am unable to do the same.
Can someone please look at the syntax below and let me know where I am going wrong.
I understand that reports are different for 6i and 10G specially .rep file but I am sure we should be able to generate a PDF file using 10G. Please let me know.

Thanks
IQ
