I have total approx 6 years of experience in AS400 technology. My project name is Atlas Copco. Here if any user got any issue, I have to debug the program and find out the issue then if any changes required in the program then I have to change. And also I work on-call, If any job went in error or failed then we need to debug the Job and find out the issue.
I have lots of hands on experience in AS400. I have also the AS400 server where I work for my project and it's related to BPCS (ERP application).
