Business partner types
To use pricing and invoicing functionality for a party, you must
		define that party as a business partner. Business partners can have various
		roles and can be of different types.
A business partner's role determines the types of transactions
		that you can perform with the business partner. A business partner type
		determines the position of the business partner in the multicompany
		environment. For example, a partner outside your organization, a logistic
		company within your organization, or a department of your
		organization.
For multicompany situations, you can define these types of
		  business partners:
External business partners
Customers and suppliers outside your own
		  organization.
Internal business partners
An internal business partner is a business partner that is linked to enterprise
			 units of the same logistic company. You must define all the business partner
			 roles for an internal business partner.
The internal business partner is used when, for example,
			 goods are transferred from a warehouse belonging to financial company F100, to
			 a warehouse that belongs to a different financial company (F200). Intergroup
			 transactions are created.
A one-to-one relationship must exist between internal
			 business partners and enterprise units. This means that you can define one
			 internal business partner for each enterprise unit.
Affiliated company business partner
Logistic companies within the same multicompany structure that
		  act as a business partner to your logistic company. You must define the Sold-to
		  and the Buy-from roles for an affiliated-company business partner before you
		  can define the enterprise modeling data in the EMM module. 
The affiliated company is used in these
				places:
- The multiplant master plan, to distinguish the dependent
				demand from the independent demand when you analyze the order file in
				Enterprise Planning.
 - Multicompany electronic data interchange (EDI) to determine
				the company for which an internal EDI message is intended.
 
You can define a business partner as an internal business
		partner or an affiliated company on the Enterprise Modeling tab of the Business Partner (tccom4100s000) session.
If you define internal business partners and affiliated-company
		business partners, you can invoice an enterprise unit or a logistic company,
		use pricing and discounts, and maintain a balance of open invoices for the
		enterprise unit or logistic company. This can be required for financial
		accounting and local tax reporting.
