Creating 10 empty records at one time does not make your process easier than if you created 10 single records one at a time. You still have to type in all the data. If this is awkward with your form, you might want to redesign the form.
There are reasons for doing what you ask but this isn't one of them based on your description.
I have an inventory app that creates multiple inventory items because the client wants them logged separately. For example, we receive 10 cases of white towels so I create 1 inventory item (with a corresponding label) for each case. This makes it easier for his warehouse to send them out again. He tells them to send case #4 and that way even though there are a hundred cases of white towels, the warehouse people know exactly which case to send to which client. It keeps inventory from getting old. If I were receiving 10 identically configured PCs, I might use the same technique and then go record by record and add in the serial numbers manually but I would probably use the technique recommended by Doc. However, if the serial numbers were sequential and so I could generate the correct serial number for each PC as part of the append, then I would certainly use an append query rather than making the user touch ten records manually.
