Choosing correct NOC

Hi everyone I have some questions regarding work experience in india
I am currently working for an MNC in a support project (as400) technology and planning for applying PR with business analyst NOC. But my work comes neither as a software developer NOC nor business analyst NOC.
Generally we need to provide all our roles and responsibilities while applying, as they enquire about our roles (in my case, which are not business analyst roles or software developer roles) . I am confused for what NOC I need to opt…
Please guide me here.thanks in advance.
