By using the f(x) button, you will find a formula window where you can create formulas based on variables that are used to calculate setup times and unit times on operation rows, and setup quantity and quantity on material rows.
These formulas and variables are applied during configuration of custom-made products in the supplement Product Configurator.
The button is activated by the settings Use time formula (only config.) and Use quantity formula (only config.), under Preparation under the Manufacturing tab in the Settings procedure.
For further description of how to use formulas, see the Formula window section in the Product Configurator chapter in the Using MONITOR Procedures guide.
