# BLUEPRINT CETAK BIRU MODUL: ADJUSTMENT (PENYESUAIAN STOK)
**Modul:** `adjustment`  
**Workspace:** `new_san_variant`  
**Standard:** Single Variant Standard & Dual-Write Rollout  
**Tanggal Analisis:** 2026-07-29

## 1. IDENTITAS MODUL

- **Nama Modul:** `adjustment`
- **Pola Kompleksitas:** **Transaksi Kompleks** (Penyesuaian Stok Lebih / Kurang per Varian Produk, Pemilihan Akun Perkiraan Selisih Stok via `_processSelectRekeningAdjustment`, Dual-Write Stock Locker Adjustment, & Reval HPP Varian).
- **Jenis Transaksi (`jenisTr`):**
  - `999` : Adjustment Stok (Penyesuaian Persediaan Barang Bervarian)

---

## 2. DAFTAR FUNGSI & LOGIKA BISNIS (REVERSE ENGINEERING)

### 2.1 Base Controller & Configuration

#### [Modul_Controller.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/adjustment/controllers/Modul_Controller.php)
- **Fungsi `__construct()`**: Load config `coTransaksiUi`, `coTransaksiCore`, `coTransaksiLayout`, `coTransaksiValues`.

---

### 2.2 Entry Adjustment & Account Selection Engine

#### [_processSelectRekeningAdjustment.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/adjustment/controllers/_processSelectRekeningAdjustment.php)
- **Fungsi `select()`, `remove()`**:
  - *Logic*: Memilih Akun Perkiraan Selisih Stok (beban kerugian selisih stok / pendapatan selisih lebih stok) yang akan dipasangkan dengan persediaan varian.

#### [Create.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/adjustment/controllers/Create.php)
- **Fungsi `index()`, `preview()`, `save()`**: Entry draf penyesuaian stok bervarian (kuantitas awal, kuantitas penyesuaian, kuantitas akhir, alasan adjustment).

---

### 2.3 Executing & FollowUp Approval

#### [FollowUp.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/adjustment/controllers/FollowUp.php)
- **Fungsi `doFollowup()`** *(Execution Adjustment)*:
  - *Query & Models*:
    1. **Dual-Write Stock Adjustment**: Memanggil `ComLockerStockDualWrite::pair()` untuk menyesuaikan stok fisik `stock_locker` dan `stock_locker_variant` (`+active` jika selisih lebih, `-active` jika selisih kurang).
    2. **Jurnal Adjustment**: Memanggil `ComJurnal` mencatat Persediaan Barang (D/K) vs Beban/Pendapatan Selisih Stok (K/D).
    3. **Registry Update**: Log step registrasi di `transaksi_registry`.

## 3. IDENTIFIKASI PERBEDAAN DENGAN MOCKUP GLOBAL

| No | Komponen / Fitur Unik | Deskripsi & Perbedaannya dengan Mockup Standar |
|:--:|:----------------------|:------------------------------------------------|
| 1 | **Adjustment Account Selector (`_processSelectRekeningAdjustment.php`)** | Sub-controller khusus untuk memilih COA / Akun Selisih Stok sebagai penyeimbang transaksi. |
| 2 | **Dual-Write Reval Stock Adjustment** | Penyesuaian stok fisik dan varian secara simultan via `ComLockerStockDualWrite` dengan aturan sentinel. |

### 4.2 Panduan Langkah-demi-Langkah Developer

1. **Langkah 1: Gunakan `ComLockerStockDualWrite` pada `FollowUp.php`**
   - Pastikan penyesuaian stok (positif/negatif) memperhitungkan `variant_id`.

2. **Langkah 2: Verifikasi COA Akun Selisih pada `_processSelectRekeningAdjustment.php`**
   - Pastikan akun selisih stok dipasangkan dengan tepat ke `ComJurnal`.

3. **Langkah 3: Verifikasi PHP 5.6 & Update UAT Checklist**
   - Lakukan linting `C:\xampp\php\php.exe -l` dan update `docs/uat-checklist.md`.
