Workflow Process

Hi All, I want to know how workflow works in Anaplan . Are there any default dimensions that we need to use for workflow. Can any please provide step by step process to set up the workflow....?  How about providing access to workflow for a user..?  How does it go to the next level i.e for approval/reject...? How can we define the complexity in/of a workflow..? Request you to provide these details in order to set up the workflow. Thanking you in Advance Regards, Sasikanth
