SAP HCM for S/4HANA Business Partner

Project overview

Initial Situation:

Two separate customer projects in the area of SAP HCM for S/4HANA (H4S4) with questions regarding the Business Partner (BP):

Customer 1: SAP HCM for S/4HANA has been productive since 11/2025, with FI/CO-ERP expected to follow on S/4HANA in 2029. For each employee, there is an Employee BP (BUP003) and an Employment Contract BP, linked via the relationship "has employment contract". The BP number of the Employee BP should match the personnel number and the later S/4-ERP. Superfluous roles (FS0005, FTB000, IHB010, UKM000) are attached to the Employee BP. Automatic synchronization has been switched off since 11/2025; BPs are being retroactively adjusted individually.

The existing BAdI implementation for /SHCM/IF_B_EE_BP_SYNC is controversial at the customer's site.

Customer 2: S/4HANA with an update to Release 2025, HCM in S/4 (H4S4) with the new Employee BP model (/SHCM/EE_BP_1). Employee Central is leading; data comes via BIB replication. Employees from companies without payroll do not have IT0006 and IT0009 and therefore do not receive an employee vendor; their travel expenses cannot be reimbursed. Cause: The grouping ECMA leads to account group KIAN, where bank details are a mandatory field (abort with CVI_API 003). Additionally, the country is stored as a mandatory field in the SAP code.

Expats with two active personnel numbers: The email address is not found, and duplicate vendors can arise.

Responsibilities

Framework data:

• Start with 3-4 days: For each customer, an analysis of the current status in the system and a reliable solution proposal; implementation will be re-evaluated together afterward
• Customer 1: Analyze BP synchronization (BAdI implementation, number ranges, groupings, roles, switched-off sync), target state for number assignment and roles with a view to S/4-ERP from 2029, plan for cleaning up existing BPs and restarting synchronization
• Customer 2: Solution path for employee vendors without bank details in companies without payroll, without HR having to maintain bank data, evaluate cases with multiple personnel numbers (email determination via IT0105/IT0712, duplicate vendors)
• Document results for each customer and present them in a meeting with the customer
• Start time: Immediately, ideally early November 2026
• Duration: Approx. 4-6 weeks (initial phase)
• Location: Remote
• Project language: German

• ABAP: BAdI /SHCM/B_EE_BP_SYNC, implicit enhancements, debugging of sync classes
