Hi
@Pelayoc, when you fulfill an order with a kit NS will automatically reduce onhand quantities for all the kit members as appropriate. Now, unless you have bins enabled and assigned to all kit members, you will not see the kit members on the fulfillment screen. Only the kit SKU itself is shown. This seems dumb, but according to SuiteAnswers it's "by design".
