Hello jayaraman,
If you are talking about automated integration between SD-Access and SD-WAN then is it roadmap for later this year. Some details about how it will work were presented at Cisco Live San Diego 2019, https://www.ciscolive.com/global/on-demand-library.html?search=brkcrs-2818#/ . Right this very moment (January 2020), before the automated integration comes, you will need to manually connect SD-WAN to SD-Access as an SD-Access IP Transit.
