I wouldn't mention a specific course unless it has some acclaim to it (i.e.: a bachelor's degree or other 'official' education pathway), or else it is listed as a mandatory requirement for the role.

As a manager, your theoretical knowledge is irrelevant to me on paper. I naturally assume you would have the skills by virtue of you applying for the role (which will be validated during the interview stage). What I care about on paper is that you are able to take a practical business problem and solve/mitigate it using your knowledge and skills. I want you to tell me that you were able to automate part of a workflow that saved 20 minutes of tedious data entry every day. Or that you were able to improve data accuracy/integrity by applying data validation and other checks. Or whatever else you've done. Your resume should promote your aptitude, not just contain a bunch of dry facts.

The only exception to this is if you are brand new to the workforce and don't have any relevant work history to speak of. In this case, listing your education is about the best you can do. But for everyone else, I highly recommend avoiding it (unless, as I say, there is a very specific reason for drawing attention to it).
