Product Model Management

1. Function Overview

Product Model Management belongs to the basic module of the MES system. It is used to build core data such as product classification, product basic information, and abnormal/defect categories for the enterprise, providing product basic data support for production planning, work order execution, quality management, and other business modules.

Core Functions:

• Product List: Maintain basic product information, support product classification management and multi-level product structure
• Abnormal/Defect Management: Maintain abnormal/defect categories for products, bind device categories for quality anomaly recording during production

3. Product Model Interaction Flow

3.1 Product List Management

3.1.1 Product List Description

Product list is core data recording basic product information, including product model, product name, etc. It is the foundation of enterprise production execution and quality management.

Product List Characteristics:

• Relevance: Product information can be referenced by process flows

Function Screenshot:

3.1.2 Add Product

Operation Steps:

1. Go to [Production Configuration] → [Product Model] → [Product List]
2. Click [Add] button
3. Fill in basic product information
4. Click [Save] to complete product creation

Field Description:

Field	Description	Required
Product Model	Unique identification code of the product	Yes
Product Name	Name of the product	Yes
Remarks	Other supplementary information	No

[Important] The product model cannot be modified after creation. Please confirm carefully when creating. [Important] Once a product is referenced by a process flow or work order, it cannot be deleted.

3.1.3 Product Query

Query Conditions:

Query Condition	Description
Product Model	Exact query by product model
Product Name	Fuzzy query by product name
Product Category	Filter by product category

Function Screenshot:

3.2 Abnormal/Defect Management

3.2.1 Abnormal/Defect Management Description

Abnormal/Defect Management is used to record abnormal situations occurring during production, including two types: NG (Not Good - non-conforming products) and ERR (Error - errors). Abnormal/defect categories are bound to device categories for anomaly recording in specific device processes.

Abnormal/Defect Types:

Type	Description
NG	Not Good, non-conforming product, products judged as non-conforming during production
ERR	Error, system or device runtime errors

Function Screenshot:

3.2.2 Add Abnormal/Defect Category

Operation Steps:

1. Go to [Production Configuration] → [Product Model] → [Abnormal/Defect Management]
2. Click [Add] button
3. Select abnormal type (NG/ERR)
4. Fill in abnormal/defect category information
5. Select the bound device category
6. Click [Save] to complete abnormal/defect category creation

Field Description:

Field	Description	Required
Abnormal Category Code	Unique identification code of the abnormal category	Yes
Abnormal Category Name	Name of the abnormal category, e.g., "Short Circuit", "Open Circuit"	Yes
Abnormal Type	NG (Non-conforming) / ERR (Error)	Yes
Device Category	Bound device category for anomaly recording on specific devices	Yes
Remarks	Other supplementary information	No

[Important] The abnormal category code cannot be modified after creation. [Important] Once an abnormal/defect category is used, it cannot be deleted.

Function Screenshot:

3.2.3 Abnormal/Defect Category Query

Query Conditions:

Query Condition	Description
Abnormal Category Code	Exact query by abnormal category code
Abnormal Category Name	Fuzzy query by abnormal category name
Abnormal Type	Filter by abnormal type: NG / ERR
Device Category	Filter by bound device category

Function Screenshot:

3.2.4 Import Abnormal/Defect Categories

The import function supports batch importing abnormal/defect category data to improve data maintenance efficiency.

Operation Steps:

1. Go to [Production Configuration] → [Product Model] → [Abnormal/Defect Management]
2. Click [Import] button
3. Download the import template
4. Fill in abnormal/defect category data according to the template format
5. Click [Select File] to upload the completed Excel file
6. Click [Start Import] to execute data import
7. View the import result report

Import Template Field Description:

Field	Description	Required	Example
Abnormal Category Code	Unique identification code of the abnormal category	Yes	NG-001
Abnormal Category Name	Name of the abnormal category	Yes	Short Circuit
Abnormal Type	NG (Non-conforming) / ERR (Error)	Yes	NG
Device Category Code	Bound device category code	Yes	DEV-SMT
Remarks	Other supplementary information	No	-

[Note] Ensure the device category exists before importing. [Tip] It is recommended to import a small amount of data first for verification, and then perform large-scale import after confirming the format is correct.

3.2.5 Batch Delete Abnormal/Defect Categories

The batch delete function supports deleting multiple abnormal/defect categories at once to improve data cleaning efficiency.

Operation Steps:

1. Go to [Production Configuration] → [Product Model] → [Abnormal/Defect Management]
2. Check the abnormal/defect categories to delete in the list (multiple selection allowed)
3. Click [Batch Delete] button
4. Confirm deletion in the pop-up confirmation dialog
5. Click [OK] to execute batch deletion

[Note] Used abnormal/defect categories cannot be deleted. [Note] Delete operations cannot be recovered. Please confirm carefully before deleting. [Tip] It is recommended to query whether the category has been referenced by work orders or anomaly records before deletion.

3.3 Abnormal/Defect Management Description

Abnormal/Defect Management is independent of products and process flows, and only has a binding relationship with device categories. Abnormal/defect categories are used to record abnormal situations occurring in devices during production.

[Important] Abnormal/Defect Management is not associated with process flows, but is directly bound to device categories. [Important] Multiple abnormal/defect categories can be bound to the same device category to achieve unified management of anomaly classification.
