SSO while directing user from ECC to MII

Hello All,

The customer has a set up in place where in he performs some of the SAP tcodes functionality via web ui on mobile device. They have a ITS url in place to access R/3 using web browser (like a following one).

<hostname>/sap/bc/gui/sap/its/test/mobile/itsmobile00?sap-client

Now the user access the above url on mobile device, enters his ECC logon credentials. Once authenticated, User sees multiple buttons present on the first screen. One of those is 'Go to MII'. On click of this button, MII login url is called and it redirects the user to MII login page. Now user enters the MII login id/password, and then the required MII web page opens up.

So it’s a 5 step process:

1. Access the web browser,
2. ECC Authentication
3. Click on ‘Go to MII’ button on first screen
4. MII Authentication
5. Access MII web page

We want to remove step# 4, by making use of SSO, so that on click of ‘Go to MII’ button, MII internally takes authentication using SSO and the user is directly directed to MII web page.

Please provide pointers how can we achieve this.

Thanks and regards,

Ruchi Agarwal
