# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

**System:** Import Comenzi Web → Sistem ROA Oracle

This is a multi-tier system that automatically imports orders from web platforms (GoMag, etc.) into the ROA Oracle ERP system. The project combines Oracle PL/SQL packages, Visual FoxPro orchestration, and a Flask web admin interface for SKU mapping management.

**Current Status:** Phase 1 (Database Foundation) - 75% Complete
- ✅ P1-001: ARTICOLE_TERTI table created
- ✅ P1-002: IMPORT_PARTENERI package complete
- ✅ P1-003: IMPORT_COMENZI package complete
- 🔄 P1-004: Manual testing packages (NEXT UP)

### Tech Stack
- **Backend:** Oracle PL/SQL packages
- **Integration:** Visual FoxPro 9
- **Admin Interface:** Flask + Oracle connection pool
- **Data:** Oracle 11g/12c (ROA system)

## Core Components

### Oracle PL/SQL Packages

#### 1. IMPORT_PARTENERI Package
**Location:** `api/database-scripts/02_import_parteneri.sql`
**Functions:**
- `cauta_sau_creeaza_partener()` - Search/create partners with priority: cod_fiscal → denumire → create new
- `parseaza_adresa_semicolon()` - Parse addresses in format "JUD:București;BUCURESTI;Str.Victoriei;10"

**Logic:**
- Individual vs company detection (CUI 13 digits)
- Automatic address defaults to București Sectorul 1
- All new partners get ID_UTIL = -3 (system)

#### 2. IMPORT_COMENZI Package  
**Location:** `api/database-scripts/03_import_comenzi.sql`
**Functions:**
- `gaseste_articol_roa()` - Complex SKU mapping with pipelined functions
- `importa_comanda_web()` - Complete order import with JSON parsing

**Mapping Types:**
- Simple: SKU found directly in nom_articole (not stored in ARTICOLE_TERTI)
- Repackaging: SKU → CODMAT with different quantities
- Complex sets: One SKU → multiple CODMATs with percentage pricing

### Visual FoxPro Integration

#### gomag-vending.prg
**Location:** `vfp/gomag-vending.prg`
Current functionality:
- GoMag API integration with pagination
- JSON data retrieval and processing
- HTML entity cleaning (ă→a, ș→s, ț→t, î→i, â→a)

**Future:** Will be adapted for JSON output to Oracle packages

#### sync-comenzi-web.prg (Phase 2)
**Planned orchestrator with:**
- 5-minute timer automation
- Oracle package integration
- Comprehensive logging system
- Error handling and retry logic

### Database Schema

#### ARTICOLE_TERTI Table
**Location:** `api/database-scripts/01_create_table.sql`
```sql
CREATE TABLE ARTICOLE_TERTI (
    sku           VARCHAR2(100),      -- SKU from web platform
    codmat        VARCHAR2(50),       -- CODMAT from nom_articole
    cantitate_roa NUMBER(10,3),       -- ROA units per web unit
    procent_pret  NUMBER(5,2),        -- Price percentage for sets
    activ         NUMBER(1),          -- 1=active, 0=inactive
    PRIMARY KEY (sku, codmat)
);
```

### Flask Admin Interface

#### admin.py
**Location:** `api/admin.py`
**Features:**
- Oracle connection pool management
- SKU mappings CRUD operations
- Web interface for configuration
- Real-time validation
