The supporting document is just that, it supports the information you’re entering in the component card. A supporting document could be a test report, or a certificate to confirm that it’s organic. It can be absolutely anything that helps support that component and be of useful reference to companies and their suppliers.   To upload an item all you have to do is tap the upload icon next to the ‘Supporting Documents’ subheading and a popup will appear.     There are two ways of uploading a file, you can either drag and drop the file into the grey box or tap the upload icon at the bottom right of the grey box.   Once you’ve uploaded the file, give the document a title and tap ‘Add’.     The supporting document has 5 actions which can be seen in the action panel; edit, preview, download, bin, and the information icon.   The edit icon allows you to rename the document.     The preview icon allows the user to preview the document.     If for whatever reason you need to download a copy of the document you have uploaded to the component you can do this by tapping the download icon.     The information icon will show when the item was uploaded, and when it was last modified with a user's name, date, and time.     The delete icon is if you no longer need this supporting document, you can tap the bin icon and remove it from that BOM component.     All of the fields you’ve entered are part of the quality aspect of the component, the next section we’ll look at the colour application to the component.
