Hello Colin,
The Product Configurator does not do anything directly with the routing line’s lot size and setup time fields.
If either of them are populated on the routing lines set up in the choices routing, their values will get copied as is if the routing line is added to the configured item.
The Product Configurator will only set the run time based on the entered quantity when it creates the routing for the configured item. After that, standard Business Central logic takes over.
Thank you,
