You order BE6k in 3 steps:
1) Order hardware, enter the top level SKU according to your needs.
for example you have: BE6K-STBDL-PLS-XU=
2) Then you order, software, enetr the top level SKU: R-CBE6K-K9
Select software version: 10.X (latest)
Select starter budle: BE6K-START-PRO25
Select FIRST-PRO (under add users for first time of CUWL pro)
Select other required options etc. and when you are finished click done.
Once done, if you expand the top level SKU R-CBE6K-K9 by clicking on + sign, you will see below automatically added at no cost, installation media for CWMS and CWMS user licenses for 25 users:
WBXMTSVR2-UWLUSRK9
WebEx Meetings Server 2.x Users
R-WBXMTSVR-UWL-K9
Webex Meetings Server 2.x Software Kit
3) Chose your subscriptions etc.
4) Add UCS hardware for CWMS (including VMware licenses)
This is pretty much it.
Any ways I hope this helps, I had to go through this through CCW to help you out.
