To select from multiple product suppliers that were added to a product, tap the checkbox of the product component supplier mapping field. This action will make a table visible for you to choose from the product supplier dropdown list.     Similarly, to select from multiple component suppliers that were added to a component in the quality information, tap the checkbox of the component supplier dropdown field. This action will display a list of all the component suppliers assigned to that product in the component supplier dropdown.     It is possible to have multiple suppliers for a single product or component, for example, if you're manufacturing in different locations or countries. This information is valuable to Bombyx because it helps to identify unique information related to a specific supplier.
