SAP MDM Workflow Add to Job Field disbled

Hi Experts,

I am trying to create SAP MDM Workflow, But in Data Manager When i create Workflow table, select records and try to add to Records (Menu)->Workflow-> Add to Job. Here Add to Job is showing me disabled. Is there any way we need to do some configuration to get it done.

Another question is, if Microsoft Visio mandatery to design Workflow Process or is there any way we can design workflow without microsoft visio. If i try to design with stencils and try to save it. It's showing me ' Start Process' is not connected. I am new to MDM Workflow. Can anyone help me to solve this problems. Thanks in advance - Vrushali
