Introduction

This blog is based on S/4HANA OP1610 release and relevant as well for subsequent releases of S/4HANA.

This blog is aimed to show 2 ways how to control Business Partner grouping based on role/role grouping selection at Business Partner creation.

1. using customizing in Customer-Vendor-Integration mapping
2. using a custom table

Business Partner transaction BP as a single point of entry to maintain customer/vendor master data, gives the possibility to have defined several Business Partner Groupings in customizing. It’s quite difficult for a user to choose the right Business Partner Grouping which is usable for Customer/Vendor roles and Customer Vendor Integration (CVI) linkage.

For both variants a BAdI implementation of BAdI BUPA_NUMBER_GROUP is used.

Update 01/20/2020
An additional BAdI is available now to control BP roles and BP groupings.

Using Customizing in Customer-Vendor-Integration mapping

Prerequisite

Usually not all Business Partner Groupings are relvant for Customer-Vendor-Integration. This solution is using mapping tables CVIC_VEND_TO_BP2 and CVIC_CUST_TO_BP2 at IMG: Cross-Application Components -> Master Data Synchronization -> Customer/Vendor Integration -> Business Partner Settings ->

For Vendor: Settings for Customer Integration -> Settings for Vendor Integration -> Define BP Role for Direction Vendor to BP

For Customer: Define BP Role for Direction Customer to BP

to determine Customer/Vendor Account Groups assigned to roles. This setup is basically done for synchronization direction Customer/Vendor -> Business Partner.

With determined Account Groups mapping table TBC001 from IMG path

For Customer: Field Assignment for Customer Integration -> Assign Keys -> Define Number Assignment for Direction BP to Customer

For Vendor: Field Assignment for Vendor Integration -> Assign Keys -> Define Number Assignment for Direction BP to Vendor

is used to determine CVI (Customer-Vendor-Integration) relevant Business Partner Groupings.

Enclosed you will find an example coding for such a BAdI-Implementation.

        iv_request->gs_navigation-bupa-creation_group = ls_dropdown_values-key.
      ENDIF.
    ENDIF.

Custom Table

Instead of using Mapping customizing you can use your own customizing table where you just store role Business Partner Grouping assingment and replace Customizing table logic in given code example by your Z-table.

Conclusion

By selecting a Customer/Vendor specific role in Business Partner creation, the system will list CVI relevant Business Partner Groupings only.
