In SAP S/4HANA greenfield implementation customers and suppliers should have same ID. Business Partner is the leading object and single point of entry to maintain Customer, Supplier (formerly known as Vendor), Contact Persons master data. In this blog post you get some insights how to migrate Customer and Suppliers master data, establish Contact Person Relationship and maintain additional partner functions.
The key and leading object is Business Partner – BP. Any BP has default 000000 Business Partner (Gen.) role. Standard Migration Cockpit object support only creation BP Customers or BP Suppliers. In case of multi-phase project implementation, you might have some of BP are already migrated during previous phases. Sometimes Customers and vendors come from different legacy systems. In order to orchestrate further migration activities good idea would be to create needed BP and only then extend them to new roles and organizational levels. Standard BP related migration objects have mandatory BP Roles structure. 000000 default role is not acceptable. Error message no. R11300 No update is defined for BP role 000000 is appeared. You can adjust Business Partner Supplier or Customer migration object and change Display View settings for S_ROLES source structure from Required to Visible.
BP roles tab has become optional in Template. You could keep it empty now.
After migration you will have Business Partner with only default 000000 Business Partner (Gen.) role and general data like BP Group, address, communication etc.
Legacy partner number BP_GEN_001 is automatically mapped to SAP BP number 1000111.
BP Customer – extend existing record by new org levels
Use standard Migration Cockpit Object – Customer – extend existing record by new org levels. As per Customer mapping was done it’s possible to use legacy number. You should use BP ID created on previous step. BP role Customer, Company Code data and Sales Organization data will be created. Template data example is as follow.
|Customer ID*||BP Role*|
|Customer Number*||Sales Organization*||Distribution Channel*||Division*||Customer Group||Currency|
|Customer Number*||Sales Organization*||Distribution Channel*||Division*||Partner Role*||Customer ID|
|Customer Number*||Company Code*||Reconciliation Account|
BP roles FI Customer and Customer are created.
BP Supplier – extend existing record by new org levels
Creation of supplier roles is the same as customer ones. Use standard Migration Cockpit Object – Supplier – extend existing record by new org levels. BP role Supplier, Company Code data and Purchase Organization data will be created.
Creating Contact Persons
You can create Contact persons using Customer or Supplier Migration Objects. Use General Data Account Person template section for naming information. BP roles – CP Contact Person.
Contact Person Relationship
Relationship to existing contact persons is out of scope in Customer migration object. In order to migrate BP Relationship new Migration Object should be created using FM BAPI_BUPR_CONTP_CREATE. Please have a look on blogpost Migrating Business Partner Relationship with S/4HANA Migration Cockpit
