SAP HCM - Human Capital Management
SAP HCM keeps each employee's record, from hire to exit, in date-effective infotypes that feed organizational management, time and payroll. In Türkiye, payroll is the core. With mainstream maintenance for ERP HCM ending by the end of 2027 at the latest, the next step now has to be decided as well.

Scope
What an SAP HCM engagement covers
Organizational management
Org units, positions, jobs and persons in PPOME, with past and future-dated changes kept in history.
Actions and infotypes
Hiring, transfer and exit with PA40; Turkish infotypes such as tax and SSI (0769), ID (0770) and severance (0776).
Time management and CATS
Absence, attendance and quota infotypes (2001, 2002, 2006), PT60 evaluation and CAT2 time sheets.
Turkish payroll (PY-TR)
SAP's TR00 schema: social security, income and stamp tax, net-to-gross, and the 5510, 6111 and 6486 incentives.
Accounting and bank transfer
PC00_M99_CIPE posts expenses and payables to FI and costs to CO; PC00_M99_CDTA builds the salary payment file.
ESS and MSS on Fiori
Leave requests F1311A, leave approval F2584, paystubs F1313A and team calendar F1309B in place of Java-based ESS.
Current state
SAP HCM in S/4HANA: H4S4 and new rules
- In on-premise S/4HANA, HCM use under the compatibility pack ended with the final transition period in May 2026. Next is separately licensed H4S4: S4HCM 100 came with 2022, 102 with 2025.
- Business function H4S4_1 is active by default from S/4HANA 2025 and cannot be reversed. It needs an H4S4 license (SAP Note 3200799) and switches off simplified functions (3091160).
- Every employee is a business partner: under /SHCM/EE_BP_1, one Employee-role BP per person and one Employment-role BP per contract (PERNR), synced by /SHCM/RH_SYNC_BUPA_FROM_EMPL.
- Legal changes arrive monthly in HR Support Packages, with country CLC packages as an additional route. Both synchronization packages, in May and November, must be implemented.
Localization
Turkish payroll and statutory filing
MUHSGK and SSI reporting
Since 07/2020 the monthly SSI notification is in the withholding and premium return (MUHSGK) filed with GİB; additional and cancellation records go in an amended return.
2026 SSI parameters
Law 7566 raised the SSI earnings ceiling to 9 times the minimum wage and the employer share of the pension premium to 12%. Table T7TRS02 has to match.
Payroll postings and e-Ledger
FI documents from the payroll posting run go into the journal and the e-Ledger submission, so any gap between payroll and the ledger must close before month-end.
E-Ledger
From the field
Notes from SAP HCM payroll projects
- Compatibility-mode HCM has run out of time. On on-premise systems that kept HCM under the compatibility pack, SAP's final transition period ended in May 2026. List the functions closed by SAP Note 3091160 first, then license H4S4 and activate H4S4_1.
- AGİ is gone, but old settings can linger. The minimum living allowance (AGİ) was abolished on 1 January 2022 and replaced by a minimum wage income and stamp tax exemption. SAP's public documentation still describes the AGİ form, so we test the exemption in a parallel run.
- Custom schemas drift from the standard. Once TR00 has been copied and changed, SAP's legal updates no longer reach the customer schema by themselves. RPU_SCHEMA_CMP, delivered with H4S4_1, compares the two; every difference goes into a change log.
- Returns bounce on missing days and job codes. A wrong T7TRS03/T7TRS04 mapping of missing-day reasons or bad data in IT0769 sends the return back for correction, and a wrong occupation code carries a fine. Run a validation report before filing.
FAQ
SAP HCM questions we hear often
What is SAP HCM?
SAP's on-premise HR core. Organizational management (OM), personnel administration (PA), time management (PT) and payroll (PY) share the same date-effective infotypes. In S/4HANA the product is called SAP HCM for SAP S/4HANA, or H4S4 for short.
When does support for SAP HCM end?
For HCM on SAP ERP 6.0 with EHP 6 to 8, mainstream maintenance ends on 31 December 2027 and paid extended maintenance runs to 31 December 2030; on EHP 5 and below, mainstream maintenance ended in 2025. For H4S4 in S/4HANA, SAP has committed to the product until 2040.
Can the HCM compatibility pack still be used after May 2026?
Not in on-premise S/4HANA: the HCM items were due to expire at the end of 2025, and SAP's final on-premise extension to the end of May 2026 has passed. On SAP S/4HANA Cloud Private Edition (new name: SAP Cloud ERP Private) systems run under RISE, SAP Note 2269324 grants rights to all compatibility packs until 31 December 2033, subject to a valid license.
What are the HR options when moving to S/4HANA?
There are three: stay on-premise with an H4S4 license; move core HR to Employee Central and keep payroll in S/4HANA (Core Hybrid); or move to Employee Central with Employee Central Payroll. Payroll complexity, cloud policy and the KVKK data protection review decide which one fits.
Does SAP payroll cover Turkish legislation?
SAP's standard Turkish localization, PY-TR, uses the TR00 schema for social security premiums, income and stamp tax, net-to-gross pay, severance and notice pay, and SSI incentives. Legal changes come through HR Support Packages and SAP Notes and need to be applied and tested in a parallel run on every system.
How do ESS and MSS work in S/4HANA?
S/4HANA has no AS Java, so Java-based ESS and MSS cannot be used; Web Dynpro ABAP or Fiori screens take their place. On the Fiori side there are leave requests (F1311A), leave approval (F2584), paystubs (F1313A) and the team calendar (F1309B). H4S4_1 adds the Organizational Chart and Employee Profile apps.
