I have a similar problem and if somebody would like to help I would appreciate it I've been a long time QuickBooks user but never got into this type of an item. I am creating groups because I make one part out of three and one of the parts I need to generate a purchase order for because it's done at another location. I have the box checked unchecked I'm sorry that says  do not print on invoices but they are generating anyway. the part number itself does not show without the line items. maybe it would be easier if I told what I want to do rather than telling you what I have done?

 I want to generate a part that is a group when I print an estimate or the sales order I want to see the part number there and a price for the part number but I do not want to see the items that make up that part. I want to I want to be able to generate a purchase order for one of the items that makes up the part so let me give you an example; I purchased sandpaper in large rolls I sell the Sandpaper by the disc and the part 4 the piece of sandpaper has two components the amount of sandpaper it would take for instance six by six and a laser cutting process which would be called cut six by six. I want to just be able to show the part number and I don't want to see everything below it, is this something that QuickBooks can do.

 I have one more question as long as I'm chatting my sales orders always used to generate a drop-down when I started the part number under sku, for some reason that has stopped there's no skew goes into the SKU column but if I generate a purchase order or an invoice from the sales order that skew is there if anybody has an answer to this I would appreciate that as well thank you
