Extending a Customer to Several Company Codes
One of the main benefits of the Business Partner concept in SAP S/4HANA is the ability to unify and share the general data of the business partner while providing the flexibility for each company that carries business with it to individually customize its key settings.
This means that if a customer is used by two or more Company Codes, it only needs to be created once in the database (thus, there will be only one customer ID number). Then, for each Company Code that will sell to this customer, the relevant Company Code can be added to the customer master record and data specific to that Company Code can be entered. For example, the reconciliation account, correspondence data, the payment terms agreed between the two parties, or the dunning information.
