With WIP Lot Trace, you can restrict the size of lots processed by a routing or routing operation. Lot-size restrictions are useful when work centers can process only certain quantities of material, or when specific operations require certain lot sizes. For example, if machine capacity lets you produce only 50 items at operation 30, then the maximum lot size would be 50.

If any lot-sizing restrictions apply in your manufacturing environment, you should list these restrictions, organized by routing, operation, and work center. It is very important to note any lot-size restrictions that differ at operations within the same routing.

The lot-size information you collect facilitates configuring the WIP Lot Trace module. You use it to create records in Routing Registration Maintenance (3.22.13.1) that limit the size of lots processed by a routing or routing operation.
