Hard to say without more details, if you're unsure you can submit a missing product report by configuring one of your supplier catalogs and clicking the Report a problem with this product link. From there you can switch over to Report a missing product. This way our catalog team can let you know if it's a product that we haven't received from the supplier, have in the system but not enough data to process it or maybe just pending processing. Keep in mind our team does have to go in and process all new products so you can expect a delay between new items being available with your supplier and them being available in DecoNetwork.
If you add a catalogue is it possible to set them all as business hub only automatically? I really don't want to have 2089 products dropped all over my online store.............. (which is why we don't use smart select)
