From 113a83c6ca4a3e5c9da9e0a6fae9b6ee3f229c45 Mon Sep 17 00:00:00 2001 From: Adrian Flores Cortes Date: Fri, 30 Jan 2026 18:13:26 -0600 Subject: [PATCH] [ERP-RETAIL] feat(purchases): Complete module integrations - email and inventory - Add email sending stub in supplier-order.service.ts with validation and logging - Add emailError field to SupplierOrder entity for tracking failed attempts - Implement purchase suggestion generation algorithm that: - Queries branch_stock for products below reorder point - Calculates average daily sales from POS order history - Determines suggested quantities based on max stock or sales forecast - Creates suggestions with priority levels (critical, high, medium, low) - Enriches suggestions with product codes from product_barcodes table Co-Authored-By: Claude Opus 4.5 --- .../entities/supplier-order.entity.ts | 3 + .../services/purchase-suggestion.service.ts | 254 +++++++++++++++++- .../services/supplier-order.service.ts | 51 +++- 3 files changed, 292 insertions(+), 16 deletions(-) diff --git a/src/modules/purchases/entities/supplier-order.entity.ts b/src/modules/purchases/entities/supplier-order.entity.ts index d30625e..e77e247 100644 --- a/src/modules/purchases/entities/supplier-order.entity.ts +++ b/src/modules/purchases/entities/supplier-order.entity.ts @@ -161,6 +161,9 @@ export class SupplierOrder { @Column({ name: 'email_sent_to', length: 100, nullable: true }) emailSentTo: string; + @Column({ name: 'email_error', length: 255, nullable: true }) + emailError: string; + // Receipt tracking @Column({ name: 'total_received_value', type: 'decimal', precision: 15, scale: 2, default: 0 }) totalReceivedValue: number; diff --git a/src/modules/purchases/services/purchase-suggestion.service.ts b/src/modules/purchases/services/purchase-suggestion.service.ts index 9d741bb..285c003 100644 --- a/src/modules/purchases/services/purchase-suggestion.service.ts +++ b/src/modules/purchases/services/purchase-suggestion.service.ts @@ -370,6 +370,11 @@ export class PurchaseSuggestionService extends BaseService { /** * Generate purchase suggestions based on stock levels + * This implementation: + * 1.
