I previously selected the Service Provider program but have not progressed to become active in the program – where can I find the ‘Progression’ button to submit?

Your account is in VPN-Enrolled status for the program. The ‘Progression’ button is on the vCAN home page in Partner Central. If you have selected more than one RTM, you may need to navigate to the vCAN home page:
Login to Partner Central.
Hover the red drop down arrow to the right of the
program name to expand the menu – select ‘VMware Partner Network-Enrolled Level Home Page’ 
Select the blue “Progression” button to complete an on-line application by providing additional company details and signing a CTA.
