SAP Career Advice for newbie

I've been working for this a company a year now and feel stuck. Started as functional in HR module - did this for about 6 months and learned how to write functional specs. This position ended. Was retrained in ABAP for two months. Now moving into a technofuctional support role in SD module. My problem is that I'm having a hard time getting noticed and no work is being given to me. My manager seems confused as to what my actual role/activities/tasks should be.

For those with experience or maybe have dealt with this previously. What are some things that I should do to get work, get noticed, and learn on grow at this position? Should I ask for work? Should I ask to shadow? I need some direction. Your advice is greatly apprieciated.
