Sap Fi

1. Environment Intake Checklist

When any FI issue is reported, collect before answering:

• SAP Release (ECC 6.0 EhPx / S/4HANA 19xx/20xx/21xx/22xx/23xx)
• Deployment model (on-premise / RISE / Cloud PE)
• Fiscal year variant (calendar / non-calendar — which month start?)
• Error message number and T-code where it occurred
• Company code (user provides — never assume)

---

2. AP — Accounts Payable

Top issues with T-code + table-level diagnosis:

Vendor invoice posting errors (FB60 / MIRO)

• Tax code not assigned: check FTXP → tax procedure → company code assignment
• Tolerance exceeded: OMR6 → tolerance key per company code (amount / percentage)
• GR-based IV mismatch: PO item → invoice tab → GR-based IV flag vs. goods receipt qty

Payment run (F110)

• No items selected: check open item due date, payment method on vendor master (LFB1-ZWELS), house bank assigned
• House bank not determined: FBZP → bank determination → ranking order → house bank / account ID
• DME file not generated: DMEE → payment medium tree format assigned to payment method

Withholding tax missing

• WTAD → withholding tax type not assigned to company code
• SPRO → FI → Withholding Tax → Extended Withholding Tax → Company Code → Assign Withholding Tax Types

Vendor master dual control

• FKMT → pending changes awaiting second approval
• Check: LFA1/LFB1 tables → field change log

Reconciliation account cannot be posted directly

• Root cause: LFB1-AKONT is a recon account (FS00 → recon account type = K)
• Fix: use FB60 (vendor invoice) or Special G/L (F-47/F-48) — never FB01 direct

---

3. AR — Accounts Receivable

Customer invoice

• FB70 (FI direct) / VF01 (SD billing — preferred for SD-integrated flows)
• Dispute management: UDM_DISPUTE (S/4HANA FSCM)

Dunning (F150)

• Dunning procedure: FBMP → dunning levels, minimum amounts, interest
• Dunning area: company code → dunning area assignment
• Block from dunning: FD02 → correspondence tab → dunning block

Credit management

• ECC: FD32 → credit limit per credit control area
• S/4HANA FSCM: UKM_BP → credit segment → limit / rule-based check
• Release blocked orders: VKM1 (orders) / VKM3 (deliveries)

Down payment process (AR)

• Request: F-37 (Special G/L indicator F)
• Down payment: F-29 (post to Special G/L)
• Clear against invoice: F-39

---

4. GL — General Ledger

Field status conflict (most restrictive rule wins)

• Check three sources: OBC4 (document type FSG) + OB14 (posting key FSG) + FS00 (G/L account FSG)
• Rule: Required > Optional > Suppressed — if any source requires, field is required

Posting period control

• OB52 → period variant → open/close periods per account type (A/D/K/M/S)
• Special periods 13–16: year-end audit / tax adjustment periods
• Assign variant to company code: OBY6

Balance carryforward

• ECC: F.16 (carry forward P&L to retained earnings account)
• S/4HANA: FAGLGVTR (Universal Journal carryforward)
• Must run after all year-end postings are complete

Foreign currency valuation

• ECC: F.05 → per valuation method, G/L account selection
• S/4HANA: FAGLFCVAL → ledger-based, parallel currency support
• Valuation method config: OB59 → exchange rate type, loss/gain accounts

Intercompany clearing

• OBYA → due-to / due-from clearing accounts per company code pair
• Cross-company document: one header, postings in two company codes automatically

5. Special G/L Transactions (Universal)

| Type | Description | Vendor T-codes | Customer T-codes | |------|-------------|----------------|------------------| | A/F | Down Payment Request | F-47 | F-37 | | F | Down Payment | F-48 | F-29 | | — | Down Payment Clearing | F-54 | F-39 | | B/G | Guarantee (statistical) | F-55 | F-49 | | W/V | Bills of Exchange | F-36 | F-33 |

Configuration check path:

• OBXT → AP Special G/L → automatic account determination
• OBXR → AR Special G/L → automatic account determination
• TBSLT → Special G/L indicator properties (noted item / statistical / free offsetting)

---

6. Asset Accounting — FI-AA

Asset master creation

• AS01 (new asset) / AS91 (legacy data transfer with historical values)
• Asset class drives: depreciation key, useful life, G/L accounts (AO90)

Asset postings

• Acquisition: F-90 (external purchase) / MIGO 101+PO (goods receipt → capitalization)
• Transfer between assets: ABUMN (within same company code)
• Partial/full retirement: ABAVN (without revenue) / ABAON (with revenue)

Depreciation run (AFAB)

• ALWAYS run test mode first → review AFBP (depreciation posting log) for errors
• Repeat run: if depreciation posted with errors → AFAB → repeat run for period
• Depreciation key config: AFAMA → period control method → base value

Year-end asset procedures

• AJAB: fiscal year close for asset accounting → prevents further postings to closed year
• AJRW: open new fiscal year → required before any posting in new year

S/4HANA difference

• New Asset Accounting only (classic AA not supported)
• Parallel ledgers mandatory for multi-GAAP scenarios
• APC values stored in ACDOCA (Universal Journal) — not separate AA tables

7. GR/IR Account Management

Universal clearing process:

1. MB5S → analyze GR/IR balances → identify aged / mismatched items
2. MR11 → automatic GR/IR clearing proposal (always simulate first — "test run")
3. Manual reversal: if PO cancelled without GR → reverse GR document (MIGO 102)
4. Month-end accrual: if GR posted but no invoice yet → accrue via FBS1 (reverse next period with F.81)

S/4HANA: GRIR Fiori app (Manage GR/IR Accounts) replaces MB5S for operational use
