In R/3 there are fewer sources for partner determination than in CRM, and you can specify only one source for each partner function to be determined. The following sources are available:

• The master data of one of the partners in the transaction
• A customer hierarchy
• The current user
• Table T024P (transaction OB51), which contains data on credit representatives
• User exits

The R/3 system most frequently uses the sold-to party's master data, but you can set it to use the master data of any partner in the transaction. Other sources that are available in CRM, such as the preceding document or organizational data, are not available for partner determination in R/3.

In CRM, there are more sources than in R/3, and you can specify as many of them as you want for each partner function to be determined. They include:

• The business partner relationships, by sales organization, of a partner in the transaction
• The general business partner relationships of a partner in the transaction
• A current partner in the transaction
• The preceding document
• Organizational data
• A pricing hierarchy
• The current user
• Business Add-Ins
