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
