PPMS reference for Netweaver 7.3, Netweaver 7.31 and Netweaver 7.4
I just released KBA 2045839 .
It has the product instance definitions of Netweaver 7.3, EHP1 for Netweaver 7.3 and Netweaver 7.4.
This is by no means everything that there is for these product versions in PPMS, but it is a start.
Let me know if you like the document.
