Tracing Lots
The lot number for a base process is its work order ID number or the lot number assigned to that order using Work Order Attribute Maintenance (1.22.4). The system automatically maintains lot-to-lot relationships for joint orders by creating receipt and issue transactions between a base process and its joint order set. These are memo transactions that do not update inventory or create GL transactions.
• Use Lot Where-Used Inquiry (3.22.4) to trace a component lot number to a base process and trace upward from the base process to the co-product and by-product lots produced from it.
• Use Lot Actual Bill Inquiry (3.22.3) to trace a co-product or by‑product lot number to the base process that produced it and trace downward to the component lots for the base process.
