Can anyone tell me more about MB 800 exam for Business Central exam and the study material if possible?

Not sure if this will help or not...

MB-800 Microsoft Dynamics 365 Business Central Functional QA | Udemy

Hello,

The MB-800 exam is the first exam for the Microsoft Business Central product. I have passed this exam and you will need to study, even if you have been an implementer for several years. Here is a study link:

If you have more questions, feel free to write back.

Hope this helps.

Thanks,

Steve
