Shift from catiav5-vb to SAP

I am presently working on catiav5-vb in a reputed software company.
I want to shift to SAP side, which modules will be best suited for me.
and more over do they ask any prior experience working on SAP if i apply for other company. I heard that SAP-BI has good prospect now.

All the modules have their own importance. Its upto you what you want to go for. when you try to go in a new company definately need need to have 2+ relevant exp on the subject.
