Link ITSM to ME51N

Hi Guys,

We just started using SAP at my company and I'm still getting used to the functionalities.

I was wondering if there's a way to link a Service Request assigned to me in ITSM to a purchase requsition in ME51N?

I'm trying to raise a purchase req. in ME51N and would like to somehow relate it to the service request.

I'd really appreciate it if someone could show me how.

Kind regards,

Paul
