With Regulatory Attributes lot control, you trace inventory and the consumption of component material lots into finished-material lots. With WLT, you trace consumption of component material lots into WIP material lots, and the consumption of WIP and additional component material lots into finished-material lots.

The two modules can work together or individually. Performance is seamless when using one or both of these related, but different, modules. Each module requires separate setup and operation.

When using automatic lot numbering features of Regulatory Attributes, the finished item lot/serial number is automatically created when the item is moved into finished item inventory. Automatic lot numbering occurs even if you are using WLT. If you are not using automatic lot numbering, you can assign a new lot/serial number to the finished item or use the WIP lot/serial for the finished item.
