Make the transition easier with Customer Vendor Integration
To enable a smooth transition from SAP ECC to SAP S/4HANA, users should first switch to the new master data object, the SAP Business Partner. Customer and supplier master data is stored here in a consolidated manner. To ensure that the different data is correctly synchronized, connected systems that are supplied with the master data are important.
One system component is the Customer Vendor Integration (CVI), which compares the business partner data with the associated customer and supplier data and also consolidates this data in the business partner master record. When implementing S/4HANA, one of two approaches must be chosen:
Brownfield or Greenfield implementation.
Whichever approach you choose, business partners must be used as the leading master data object and the single entry point for maintaining customers and suppliers.

Are you currently in the process of switching to SAP S/4HANA or implementing SAP S/4HANA?
Here are some things you should know before you start using CVI:
Make sure that the use cases are clearly mapped out – various parameters should be defined with the departments, such as relationships or grouping characteristics. The master data concept must cover the actual use cases.
Plan training for all affected employees – to avoid errors and uncertainty, all employees in your company should be trained in the changeover.
Start several test runs - check several times whether the master data quality is sufficient. For example, you should check that the postal address of the customer and supplier match. Note that the two master records should be linked in an SAP table so that they can be transferred smoothly to the new ERP system.
