+# Custom Product Code & Item Code Automation
+
+## Overview
+Odoo 17/19 Community tidak punya field `code` standar untuk product category. Untuk kebutuhan stock keeping unit (SKU) yang unik, kita buat field `item_code` yang di‑generate otomatis dari:
+
+```
+item_code = parent_category_code (2 digit) + category_code (2 digit) + product_id (4 digit) + name_slug (lowercase, no space)
+```
+
+Contoh:
+- Kategori anak: id=06, parent=01 → prefix = `0106`
+- Produk: id=3, nama="Backup BRT 30 x 36 x 1,25 mm"
+- Hasil: `01060003backupbrt30x36x1,25mm`
+
+## Implementation Steps
+
+### 1. Extend `product.category` → field `code`
+```python
+class ProductCategory(models.Model):
+    _inherit = 'product.category'
+    code = fields.Char(string='Category Code', compute='_compute_code', store=True, size=4)
+
+    @api.model_create_multi
+    def create(self, vals_list):
+        records = super().create(vals_list)
+        for r in records:
+            r.code = f'{r.id:02d}'
+        return records
+```
+
+### 2. Extend `product.template` → field `item_code`
+Field `item_code`:
+- **Stored** (`store=True`) — dipakai untuk pencarian & unique index.
+- **Read‑only di view** — tidak boleh ditulis manual.
+- **On‑change preview** → tampilkan prefix kategori saat buat produk baru.
+
+```python
+class ProductTemplate(models.Model):
+    _inherit = 'product.template'
+
+    item_code = fields.Char(string='Item Code', store=True, readonly=False)
+
+    _sql_constraints = [
+        ('item_code_unique', 'UNIQUE(item_code)', 'Item Code harus unik.'),
+    ]
+
+    @api.model_create_multi
+    def create(self, vals_list):
+        records = super().create(vals_list)
+        for r in records:
+            r.item_code = r._full_item_code(r)
+        return records
+
+    def write(self, vals):
+        res = super().write(vals)
+        if 'name' in vals or 'categ_id' in vals:
+            for r in self:
+                r.item_code = r._full_item_code(r)
+        return res
+```
+
+### 3. Extend `product.product` (varian)
+Untuk produk ber‑varian, `item_code` diturunkan via related field ke template:
+
+```python
+class ProductProduct(models.Model):
+    _inherit = 'product.product'
+
+    item_code = fields.Char(
+        string='Item Code',
+        related='product_tmpl_id.item_code',
+        store=True,
+        readonly=True,
+    )
+```
+
+### 4. XML View — field read‑only
+```xml
+<!-- product_template_form_view inheritance -->
+<field name="default_code" position="after">
+    <field name="item_code" readonly="1" placeholder="Terisi otomatis"/>
+</field>
+```
+
+### 5. PostgreSQL — Unique Index (optional, backup)
+Constraint `__sql_constraints` sudah menambah unique index via Odoo ORM. Untuk kecepatan lebih cepat di PostgreSQL level, dapat manual:
+
+```sql
+CREATE UNIQUE INDEX IF NOT EXISTS product_template_item_code_uniq
+ON product_template (item_code) WHERE item_code IS NOT NULL;
+```
+
+### 6. Migration — isi data existing
+```python
+env.cr.execute("""
+    CREATE UNIQUE INDEX IF NOT EXISTS product_template_item_code_uniq
+    ON product_template (item_code) WHERE item_code IS NOT NULL
+""")
+
+cats = env['product.category'].search([])
+for c in cats:
+    if not c.code:
+        c.code = f'{c.id:02d}'
+
+prods = env['product.template'].search([])
+for p in prods:
+    p.item_code = p._full_item_code(p)
+```
+
+## Pitfalls
+- `@api.depends('id')` **not allowed** di Odoo 19. Namun `id` tersedia di `create()` setelah super() selesai.
+- Field `code` di kategori **harus `size` ditentukan** ( Odoo 17+ lint error tanpa `size`)
+- Product dengan `categ_id = False` → gunakan fallback `00`.
+- **Item Code read‑only di view**: bila pakai `store=True`, field tetap dapat ditulis via ORM (API). Untuk mencegah manual edit, gunakan `readonly=True` + `@api.constrains` untuk validasi.
+
+## References
+- `models/product_template.py` — contoh implementasi lengkap (sudah ada di addon `kosbar_erp_ext`)
+- `views/product_views.xml` — XML view inheritance

+# Template Import Odoo
+
+Folder ini berisi contoh file template untuk import master data ke Odoo ERP.
+
+## Isi Folder
+| File | Kegunaan |
+|---|---|
+| `import-products.xlsx` | Template import produk (Product Name, Category, Price, Cost, Barcode) |
+| `import-product-categories.xlsx` | Template import kategori produk (Name + Parent Category) |
+| `import-product-categories.csv` | Versi CSV kategori (untuk referensi/format cepat) |
+
+## Cara Pakai
+1. **Kategori dulu, baru Produk** (Produk butuh kategori yang sudah ada).
+2. Buka Odoo → **Inventory/Sales → Configuration → Product Categories** → tombol **Import**.
+   - Petakan: `Nama Kategori` → `Name`, `Parent Category` → `Parent Category`.
+3. Setelah kategori masuk, `code` 2-digit otomatis terisi oleh addon.
+4. Buka **Inventory/Sales → Products → Products** → tombol **Import**.
+   - Petakan: `Product Name` → `Name`, `Product Category` → `Product Category`, dll.
+5. **Jangan isi** kolom `Item Code`/`Internal Reference` — otomatis di-generate addon.
+   - Format: `parent_code + child_code + product_id(4) + nama_lowercase_tanpa_spasi (koma → titik)`.
+
+## Contoh hasil otomatis
+- Kategori `Elektronik` (code `01`), kategori `Laptop` (code `04`, parent `Elektronik`), produk `MacBook Air M2` (id `0001`):
+  - `item_code = 01040001macbookairm2`
+## Opsi cli
+ ```bash
+  python3 -m venv /tmp/xlsxenv && /tmp/...
+  ```
