Lack of Workplace Logic

I was reassigned from my last project 2 years ago. One of the executives from that project [not with my company] went to the VP of my company asking for my help with past due reporting for the project I no longer work on. The VP told him to reach out to me directly. Does that mean i get the option to say 'No'?

I don't understand why someone who is still working on the project can't do the reporting. I guess that would make too much sense.🙄 I have moved on to other responsibilities. What would you do?
