Could someone clarify the difference between procurement categories in a procurement hierarchy and a procurement catalog?
From what I understand, once I define a procurement category and link products or vendors to it, I can use it for purchase requisitions and orders without needing a procurement catalog.
It seems that procurement catalogs were primarily used with the Enterprise Portal, which has been deprecated in the latest version of D365FO and isn't part of Employee Self-Service. Given this, I'm not sure why both would be necessary.
Thanks in advance for your help!
