AX 2009 Submit Button on PO Workflow

Hi Everyone,

I’m quite new with AX and I need your help. We just got a new PO workflow and there seems to be no SUBMIT button. On our old and existing PO workflow there’s one. Can you please help me on how to enable/show the SUBMIT button?

If it’s not too much to ask can I get a step by step procedure as I am really new with AX.

Thanks a lot!
