One of the major activities in an SAP S/4HANA on-premise conversion project is to implement Customer/Vendor Integration (CVI) and create Business Partners for customers, vendors, and contact persons in the SAP ERP system before the start of S/4HANA system conversion. SAP Note 2265093 explains this prerequisite for converting an SAP ERP system to SAP S/4HANA. I have put together a document explaining the entire CVI process in a step by step format to help consultants engaged in S/$HANA conversion projects. My colleagues and I from SAP’s S/4HANA Regional Implementation Group (RIG) have supported a number of S/4HANA projects globally and have been directly involved in assisting our customers with the CVI/conversion process. Based on our experience, I have added a section called lessons learned where I have provided a list of the commonly encountered issues and solution approaches taken by different customers.

I will be updating this document with additional information as needed. Your comments and suggestions to improve this document are welcome.
