SAP SD Partner Function

Partner Functions
Sold to Party :
A person or company that places an order for goods or services.
The sold-to party can perform the functions of the payer, bill-to party,
or ship-to party.
Ship to Party :
A person or company that receives goods.
The ship-to party may not necessarily be the sold-to party, the bill-to
party, or the payer.
Payer :
A person or company that pays the bill.
The payer may not be the bill-to party.
Bill to Party :
A person or company that receives the invoice for a delivery or service.
The bill-to party may not necessarily be the payer of the bill.
Customer partner functions
The company or person who places an order can be the same company
or person who receives the goods and the invoice and pays. Because this
customer assumes all partner functions, you create one master record
for the customer. You create a customer master record for the sold-to
party in which you enter data required for the other partner functions.
