These options change the behaviour for when assemblies and components are added to a quote/order. Assemblies are setup with components and allow easy adding of related products to a quote/order.
Click: System Config (main toolbar) > Assemblies
Prompt before adding
You will see a selection window when adding the main assembly
Add without prompting
All products are added automatically, and no selection window is displayed when adding to the quote.
Never add
Will ignore all the component products and only add the main product you have selected.
Ask before applying rules based changes
When an assembly has rules attached, ticking this option will mean it will make the software ask for confirmation before any changes.
