# BLUEPRINT CETAK BIRU MODUL: REQUEST STOK (INTER-WAREHOUSE STOCK REQUISITION)
**Modul:** `requeststok`  
**Workspace:** `new_san_variant`  
**Standard:** Single Variant Standard & Dual-Write Rollout  
**Tanggal Analisis:** 2026-07-29  

---

## 1. IDENTITAS MODUL

- **Nama Modul:** `requeststok`
- **Pola Kompleksitas:** **Transaksi Kompleks** (Permintaan Mutasi Stok Antar-Gudang / Cabang, Variant Picker Request via `_processSelectProduct`, Otorisasi Manajer Gudang, & Workflow Pemenuhan Transfer).
- **Jenis Transaksi (`jenisTr` Utama):**
  - `761`: Permintaan Stok Barang (Stock Requisition Order)
  - `763`: Permintaan Transfer Inter-Gudang

---

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

### 2.1 Base Controller & Configuration

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

---

### 2.2 Entry Permintaan Stok & Variant Selector

#### [_processSelectProduct.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/requeststok/controllers/_processSelectProduct.php)
- **Fungsi Variant Stock Requisition Selector**:
  - *Input*: Gudang Pemohon (Destination Warehouse), Gudang Pemenuh (Source Warehouse), Produk ID, Variant ID, Jumlah Permintaan.
  - *Logic*: Menyusun draf dokumen permintaan stok tanpa mengunci fisik stok (non-locking requisition phase) sampai disetujui untuk transfer.

#### [Create.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/requeststok/controllers/Create.php)
- **Fungsi `index()`, `preview()`, `save()`**: Entry draf formulir permintaan stok barang bervarian.

---

### 2.3 Executing & FollowUp Approval

#### [FollowUp.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/requeststok/controllers/FollowUp.php)
- **Fungsi `doFollowup()`** *(Execution Stock Requisition)*:
  - *Query & Models*:
    1. **Approval Status Update**: Mengubah status permintaan dari Draft -> Approved -> Fulfilled.
    2. **Transfer Linkage**: Meneruskan persetujuan permintaan menjadi pesanan pengeluaran di modul `pindahgudang`.
    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 | **Non-Locking Requisition Workflow** | Tahap pengajuan permintaan stok yang belum memotong saldo fisik locker (hanya pesan komitmen). |
| 2 | **Inter-Branch Warehouse Routing** | Pemetaan gudang sumber dan pemohon antar-cabang secara otomatis. |

### 4.2 Panduan Langkah-demi-Langkah Developer

1. **Langkah 1: Gunakan Variant Selector pada `_processSelectProduct.php`**
   - Mengakomodasi permintaan spesifik `variant_id` barang.

2. **Langkah 2: Integrasikan Pemenuhan ke Modul `pindahgudang` pada `FollowUp.php`**
   - Otorisasi pengeluaran stok fisik saat disetujui.

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