# IA: Tech hands borrowed SKU; ordered barcode back to stock

**Batch:** 78  
**Example:** GH4057-REINHA-C20 (`19c74639f26cdb08`)

## Lesson
- Callout paid for NO-STOP/1 ordered barcode; Gerald gave borrowed unit to client instead.
- Warehouse must put ordered barcode **back to stock** and record borrowed-unit issue — do not leave ordered line consumed.
