Product Automatic Repair

Introduction

ProductAutomaticRepairActivity is a MES-specific automatic repair node for defective products, used to automatically create repair judgment records for products. This node can automatically create corresponding judgment records for products based on the configured judgment result type (NG Product Flow, Manual Repair, Equipment Repair, Product Scrap), realizing automated processing flow for defective products.

Configuration Items

This node is controlled via process configuration and flow context variables.

Error Handling

Error Scenario	Result Value	Error Message
Function Not Enabled	2	Recipe Distribution Disabled
Product Code Empty	2	Product code cannot be empty
Judgment Format Error	2	Judgment result format incorrect: 1=NG Flow, 2=Manual Repair, 3=Equipment Repair, 4=Scrap
Creation Failed	2	Specific error info
System Exception	2	Exception info

Notes

1. Function Enable: Needs to enable automatic repair function in process configuration.
2. Product Code Required: Product serial number is a required parameter.
3. Type Validation: Judgment result must be a valid enum value (1-4).
4. Operator Record: System automatically records current operator info.
5. Exception Handling: Exceptions during judgment creation are captured and recorded.
6. Result Check: Recommended to check execution result in subsequent nodes.
