In this step, you define partner determination schemas.
Partner schemas allow you to group various partner roles. You can specify that certain roles in a schema are mandatory, i.e. cannot be changed after entry.
You have the option of defining different
partner schemas at different data retention levels within the vendor master
record.
For example, you can have a different ordering address at the more specific
level "purchasing organization/vendor sub-range/plant" than at the more
general level of the purchasing organization.
