Partner Processing: Overview 

Use

The partner tab page in business transactions gives you an overview of partners, determined by partner processing, involved in a business transaction. You maintain your master data and set partner determination procedures for business transactions in Customizing. When you create a business transaction the system reads the partner determination procedure, finds the master data and automatically enters it into the document. You can add, delete, and redetermine any partners or partner functions manually on the partner tab page.
