Is tracking Churn/NRR the sole role of Sales Ops?

I'm the sole SOps person at my org and they're not fully familiar with Sales Ops. I've been here for 19 months. I think their lack of understanding also blurs lines.

My boss (ceo) wants to have better insight and tracking of churn, nrr, grr, etc. I'm just wondering how much of this is my purview? We have a finance team. We have multiple finance teams across our org (made up of numerous business units). They have their ERP/SAP/biling system. I don't oversee nor have access to these.

Some of our business units already track these metrics and, well, it done via their finance teams.

I can do it but wondering if it adds an extra step? Because I'd need to collect the data from finance anyway, and I'm not fluent in ERP report layouts/structures or anything related to accounting, etc.

I'm just curious. I'm 5 years into SOps, and this is the 1st org I've worked for where I'm the only SOps person so, there's a lot I'm not sure if is appropriate or not. Thank you.
