## 1. Order-to-Cash Flow

```
Inquiry (VA11) → Quotation (VA21) → Sales Order (VA01)
→ Outbound Delivery (VL01N) → Picking (LT0A / VL02N)
→ Post Goods Issue / PGI (VL02N) → Billing (VF01)
→ FI Document created → Customer Payment
```

---

## 2. Sales Order Issues

**Pricing errors**
- Condition records: VK11 (create) / VK12 (change) → access sequence → condition table
- Pricing procedure determination: OVKK → sales area + doc pricing procedure + customer pricing procedure
- Manual price change: VA02 → Conditions tab → manual entry (if field status allows)
- Pricing analysis: VA02 → Conditions → Analysis (shows why each condition applied / not applied)

**Availability check**
- CO09: availability overview per material / plant / checking rule
- Checking rule: OVZ9 → scope of check (purchase orders / production orders / safety stock)
- Partial delivery: schedule line category → delivery block vs partial confirmation

**Credit check**
- ECC: FD32 → credit limit per credit control area → exposure = open orders + deliveries + billing + FI
- S/4HANA FSCM: UKM_BP → credit segment → scoring + limit → automatic rule-based check
- Release blocked: VKM1 (orders) / VKM3 (deliveries) / VKM4 (deliveries without order)

**Output (forms / messages)**
- NACE → output type → condition records → access sequence
- Output not triggering: check condition record exists for correct sales org / doc type / partner

**Incompletion log**
- V.02 → list incomplete sales orders
- Incompletion procedure: OVAU → mandatory fields per item category / schedule line category

---

## 3. Delivery and Goods Issue

**Delivery creation**
- VL01N: manual delivery → or automatic from VF04 billing due list
- Delivery split: copy control VTLA → split criteria (shipping point / route / delivery date)
- Collective delivery: VL10A (from sales orders) / VL10B (from purchase orders)

**Picking and Transfer Orders**
- LT0A: create transfer order for warehouse picking
- VL02N: confirm transfer order → update picked quantity

**Post Goods Issue (PGI)**
- VL02N → Post Goods Issue button
- PGI errors: stock insufficient (MMBE check) / batch locked / serial number missing
- PGI reversal: VL09 → reverse goods issue (if billing not yet done)

**Batch determination**
- VCH1 → batch search strategy → sort / selection criteria
- CH1 → batch search strategy in delivery

---

## 4. Billing

**Billing due list (VF04)**
- Billing block on order: VA02 → Billing tab → remove block
- Billing block on delivery: VL02N → remove billing block

**Billing types**

| Type | Description | Reference |
|------|-------------|-----------|
| F2 | Standard invoice | Delivery |
| G2 | Credit memo | Credit memo request |
| L2 | Debit memo | Debit memo request |
| F5 | Pro forma (order-based) | Sales order |
| F8 | Pro forma (delivery-based) | Delivery |
| IV | Intercompany invoice | Delivery |
| RE | Returns credit | Return delivery |

**Invoice cancellation**
- VF11 → cancel billing document → creates cancellation document (S1)
- Reversal posts offsetting FI document

**Collective billing**: VF06 → mass billing run → select + process

---

## 5. Pricing

**Condition technique structure**
```
Pricing Procedure
  └── Condition Types (PR00, K007, KF00, etc.)
       └── Access Sequences
            └── Condition Tables (key combinations)
                 └── Condition Records (VK11)
```

**Common condition types**

| Type | Description |
|------|-------------|
| PR00 | Base price |
| K004 | Material discount |
| K005 | Customer/material discount |
| K007 | Customer discount (%) |
| KF00 | Freight surcharge |
| MWST | Output tax |

**Rebate processing**
- VB01: create rebate agreement → conditions → accrual rate
- VB02: manual accrual update
- VB07: rebate settlement (partial / final)
- Rebate must be activated in customer master (billing tab) and sales org config

---

## 6. Credit Management

**ECC Credit Management**
- FD32: credit limit → credit control area → risk category → credit limit amount
- Credit exposure: open order value + open delivery value + open billing + open FI items
- Credit check triggered at: order save / delivery creation / goods issue (configurable per risk cat)

**S/4HANA FSCM Credit Management**
- UKM_BP: credit master per customer → credit segment → scoring rules
- UKM_MY_LIMIT: credit limit workflow and approval
- Rule-based: automatic scoring → automatic limit assignment
- Event-driven: real-time exposure calculation from Universal Journal

**Release workflow**
- VKM1: list of blocked orders → select → release
- VKM3: list of blocked deliveries → release
- Automatic re-check: after release, re-check at next critical step

## 7. SD Account Determination (VKOA)

FI document created at billing uses account keys from pricing procedure:

| Account Key | Usage |
|------------|-------|
| ERL | Revenue account (main sales revenue) |
| ERS | Sales deduction / discount |
| ERF | Freight revenue |
| VSE | Sales tax |
| EVV | Cash discount provision |

VKOA: assign G/L accounts per combination of:
Application + Condition type + Account key + Chart of accounts + Sales org + Account assignment group (customer/material)

|-------|-----|---------|
| Revenue recognition | VBREVN / VF44 | IFRS 15 POB approach |
| Credit management | FD32 | FSCM / UKM_BP |
| Availability check | CO09 | Same (enhanced with MRP Live) |
| Pricing | Same condition technique | Same + enhanced Fiori apps |
| Billing output | NACE | Output Management (BRF+) |
| SD→FI posting | Same | Direct to ACDOCA |
