BP and CVI in SAP S/4HANA System Conversion

Content updated on October 3, 2022.

One of the major activities in an SAP S/4HANA system conversion project is implementing Customer Vendor Integration (CVI) and creating Business Partners for customers, vendors, and contact persons in the SAP ERP system before the start of S/4HANA system conversion. Business Partner Approach is an important simplification item in SAP S/4HANA as explained in SAP Note 2265093. The note also indicates that CVI implementation is a prerequisite for converting an SAP ERP system to SAP S/4HANA. My colleagues and I from SAP’s S/4HANA Regional Implementation Group (RIG) have supported several S/4HANA projects globally and have been directly involved in assisting our customers with CVI implementation and synchronization. Based on our experience, I have put together a document explaining the entire CVI Synchronization process in a step by step format to help consultants engaged in S/4HANA conversion projects. The document covers the following topics within BP and CVI.

  • BP & CVI in S/4HANA – Overview
  • Handling Custom Enhancements
  • CVI Synchronization Process (Preparation, Synchronization, and Post System Conversion Activities)
  • Impact on Interfaces
  • Lessons Learned
  • Approach and Recommendation

      Hello Chelliah,

      in the latest provided version of step by step guide for implementing CVI in SAP ERP
      ''SAP S/4HANA - Business Partner & Customer Vendor Integration'' from march 2020
      the previously defined step in post conversion activities
      ''For Post Processing tasks, you may use Best Practice Building Block J61 as a reference.''
      was not listed furthermore.
      Also this scope (J61) item and related scope item (BN4) cannot be found in Best Practices
      for SAP S4/HANA 1909 LATEST.
      Are these activities not relevant and is there an alternate process? If not, can you please
      provide to me a link, where I can display the actual conversion guides for BN4 and J61?
      Thank you in advance for Your help
