Steps:
- Add all spare parts as products into the website. Process is exactly like adding a normal product but make sure: product is marked as schematic, it will have only the default variant and you enable and add prices and stock available to that variant. All level of prices must be set otherwise variant & item will be made disable and you will be able to add to the schematic
- Add a product and mark it as SCHEMATIC& it is only schematic (cannot be bought as a product).No need to set any variant and prices. Very important is to go to SCJEMATIC section and follow instruction in video bellow.
- Add/attach spare parts (already added as products) to the schematic
- Add/Attach attached spare parts (step above) to specific area on the diagram
