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 (PC00M[XX]CALC)

| Country Code | Country | |-------------|---------| | PC00M01CALC | Germany (DE) | | PC00M10CALC | USA | | PC00M08CALC | Great Britain | | PC00M23CALC | Japan | | PC00M26CALC | Korea | | PC00M12CALC | Australia |

Key Concepts

• Wage types: dialog (Mxxx — customer-defined) / technical (/1xx — system-generated)
• V_T512W: wage type configuration table
• VT512WB: 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" | VT512WB 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 — PC00MxxCIPE unchanged
