1. Environment Detection (Critical — Ask First)
□ Scenario A — ECC HCM (classic on-premise, pre-S/4HANA)
□ Scenario B — HCM Compatibility Pack on S/4HANA (2020 / 2021)
□ Scenario C — HCM for S/4HANA / H4S4 (S/4HANA 2022+, BF H4S4_1 active)
□ Payroll country? (country-specific PC00_M[XX] where XX = country code)
□ SuccessFactors integrated? (hybrid or standalone HCM?)
⚠️ Strategic Context — Always Share with User
- ECC HCM mainstream support ends 2027 (extended maintenance to 2030 with additional fee)
- HCM Compatibility Pack usage rights expired end of 2025
- H4S4_1 business function activation is IRREVERSIBLE — warn before recommending activation
- H4S4 is a bridge — no major new functionality planned by SAP; SuccessFactors is strategic direction
- For SuccessFactors-specific topics, refer to the sap-sfsf skill
2. Personnel Administration (PA)
Core concept: infotype-based data model — all employee data stored in versioned, date-effective records
Key T-codes:
- PA20: display HR master data
- PA30: maintain HR master data (create / change / delete infotypes)
- PA40: personnel actions (hire / transfer / terminate)
Key Infotypes
| IT | Name | Key Fields |
|---|
| 0000 | Actions | Action type, reason |
| 0001 | Org Assignment | Company code, pers.area, EG, ESG, position |
| 0002 | Personal Data | Name, birth date, nationality |
| 0006 | Addresses | Address type, street, city, country |
| 0007 | Planned Working Time | Work schedule rule, time mgmt status |
| 0008 | Basic Pay | Pay scale type/area/group, wage types, amounts |
| 0009 | Bank Details | Bank key, account number, payment method |
| 0014 | Recurring Payments/Deductions | Wage type, amount, frequency |
| 0015 | Additional Payments | One-time wage type, amount |
| 0027 | Cost Distribution | Cost center / order split for payroll posting |
Common Errors
| Error | Root Cause | Fix |
|---|
| "Infotype record not found" | IT does not exist for employee | PA30 → create new record |
| "Feature ABKRS not maintained" | Payroll area derivation feature | PE03 → feature ABKRS → edit decision tree |
| "Time constraint violation" | Overlapping date-effective records | PA30 → delimit existing record before creating new |
| "No authorization" | Missing P_PERNR or PLOG auth | SU53 → check missing auth object |
3. Organizational Management (OM)
Object Types
| Object | Type Code | Description |
|---|
| Organizational Unit | O | Department / division |
| Position | S | Individual post (links to person) |
| Job | C | Job title / job description |
| Person | P | Individual employee (linked from PA) |
| User | US | SAP user account |
Key T-codes:
- PP01: general object maintenance
- PPOCE: org structure editor (hierarchical view)
- PPOME: org management for managers (MSS)
Relationships
| Relationship | Description |
|---|
| A/B 002 | Reports to / is manager of |
| A/B 007 | Is described by / describes (Job ↔ Position) |
| A/B 008 | Is holder of / is occupied by (Position ↔ Person) |
| A/B 003 | Belongs to / includes (Org Unit ↔ Position) |
Common Issues
| Issue | Fix |
|---|
| Position not showing in org chart | PP01 → check validity dates (start/end) and active flag |
| Person not linked to position | RHINTE00 → consistency check; then PA30 IT0001 → fix position assignment |
| Structural auth not working | T77PR / T77UA → check structural authorization profile assignment |
4. Payroll (PY)
Payroll Flow
1. Release payroll PA03 → status: "Released for payroll"
2. Run payroll PC00_M[XX]_CALC (XX = country code)
3. Check log Display log → identify error employees
4. Corrections PA03 → "Release for correction" → fix master data → re-run
5. Exit payroll PA03 → "Exited"
6. Post to FI/CO PC00_M[XX]_CIPE → SIMULATE first → then actual run
7. Bank transfer PC00_M[XX]_CDTA → generate DME file
Country-Specific Payroll T-codes (PC00_M[XX]_CALC)
| Country Code | Country |
|---|
| PC00_M01_CALC | Germany (DE) |
| PC00_M10_CALC | USA |
| PC00_M08_CALC | Great Britain |
| PC00_M23_CALC | Japan |
| PC00_M26_CALC | Korea |
| PC00_M12_CALC | Australia |
Key Concepts
- Wage types: dialog (Mxxx — customer-defined) / technical (/1xx — system-generated)
- V_T512W: wage type configuration table
- V_T512W_B: wage type permissibility per infotype
- Schemas: country-specific payroll logic (X000 DE / U000 US / etc.)
- PE01: schema editor — edit payroll calculation logic
- PCRs (Personnel Calculation Rules): PE02 — individual calculation rules within schema
- Payroll periods: T549Q → period parameters per payroll area
- Retro accounting: triggered automatically when backdated IT0008/IT0014/IT0015 changes
Common Errors
| Error | Root Cause | Fix |
|---|
| "Payroll area locked" | Another run in progress or locked | PA03 → check status → unlock if safe |
| "No valid personal work schedule" | IT0007 missing or date gap | PA30 → IT0007 → fill gap |
| "Wage type not permitted" | V_T512W_B permissibility check | SPRO → Payroll → Wage Types → check permissibility |
| "FI posting error — account not found" | Symbolic account → G/L mapping missing | V_T52EL → wage type → symbolic account; SPRO → G/L assignment |
5. Time Management (TM)
Configuration Hierarchy
Holiday Calendar (SCAL)
→ Factory Calendar (SCAL)
→ Daily Work Schedule (PT01 view)
→ Period Work Schedule
→ Work Schedule Rule
→ IT0007 (Planned Working Time)
Key T-codes
| T-code | Description |
|---|
| PT01 | Display/create work schedules |
| SCAL | Factory / holiday calendar |
| PT60 | Time evaluation (RPTIME00) |
| PT_BPC10 | Time accounts / leave quotas |
| RPTQTA00 | Quota generation run |
| CAT2 | CATS — cross-application time sheet |
| PT50 | Quota overview for employee |
Common Issues
| Issue | Root Cause | Fix |
|---|
| Absence quota not generated | RPTQTA00 selection / IT0007 TM status ≠ 1 | Run RPTQTA00 with correct selection; check IT0007 TM status |
| Time evaluation errors | Schema logic / master data gap | PT60 → log → identify error → check schema TM00/TM04 in PE01 |
| Overtime not calculated | PCR threshold / daily-weekly limit | PE02 → time PCR → check overtime conditions |
6. FI/CO Integration (Payroll Posting)
Posting Flow
PC00_Mxx_CIPE (simulation) → Preview FI document
→ PC00_Mxx_CIPE (actual) → HCM cluster posting document
→ PCRV / PUOC_xx → FI document in target company code
Mapping Chain
Wage type → Symbolic account (V_T52EL) → G/L account (SPRO assignment)
Cost Assignment
- IT0027 (Cost Distribution): split payroll costs across cost centers / internal orders / WBS
- Without IT0027: cost posted to cost center from IT0001 (Org Assignment)
7. H4S4 Guidance (S/4HANA 2022+)
Before Recommending H4S4_1 Activation
- Run impact assessment: SAP Note 3091160 — check which functionalities are deprecated
- Activation is IRREVERSIBLE — no rollback possible after activating H4S4_1 via SFW5
- Some PA / TM / PY functionalities deprecated — must have replacement plan
What Changes with H4S4_1
- Fiori apps added: My Paystub, Leave Request, Team Calendar, Manager Self-Service apps
- Learning Solution: NOT available in Private Cloud → must use SuccessFactors Learning
- Some classic PA/TM reports replaced by Fiori equivalents
What Stays the Same
- Core payroll engine — schemas, PCRs, wage types unchanged
- Infotype data model — PA30 still works
- Time management configuration — work schedules, PT60 unchanged
- FI/CO posting logic — PC00_Mxx_CIPE unchanged
