Hi Grace
Unless you could argue that the training is relevant for your industry and to help the business perform better, I'm not sure that it would count. This image from PMI might help you identify whether the training you are considering could fit into any of the Talent Triangle areas:

You can also count your work as a practitioner towards your PDUs, so maybe that's another area where you could look to pick up some extras?
Post PMP, i worked as Product Owner instead of Project Manager. As a product owner I regularly share the functionality of app that team is developing ( not related to project management)
and planning to attend a SQL training (again non project management domain) this year. Question is can i report PDU for non-project management related domain?
