1672336 - Clarification of SPM "Prerequisites"

Spend Performance Management Release Information Notes and Service Pack release notes all contain a "Reasons and Prerequisites" section defining the "Recommended Pre-Requisite" for that release.

If a later NW SPS is already available, does the recommendation mean that at least the prerequisite NW SP can be installed or is the recommendation that exactly the SP level of the prequisite has to be installed?

If an earlier NW SPS is already installed, does the customer have to upgrade to the NW SPS stated in the "Recommended Prerequisites"?
