Before implementing SSO for SAP MBO packages, configure the MBOs so client credentials can be propagated to the EIS and, if enabling SSO for a Workflow application, add the appropriate starting point.
Configure the Workflow application to use SSO2 or X.509 credentials by adding and configuring a credential starting point for the workflow application. See Configuring the Workflow Application to Use Credentials in the Developer Guide: Mobile Workflow Packages for details.
