Difference between XD01 and VD01

Hello Gurus,

I need some expert advise on these transactions ie XD01 and VD01. If I create a customer with VD01 what will be the major difference.

I know that

XD01 - Create Customer Centrally (Has company code data)

VD01 - Sales and distribution customer (w/o company code data)

Also can if I create only customers with vd01 transaction how will finanacial accounting take place.

Can u also tell me which business processes can get affected.

Regards

Mahesh
