Mike,
You should call your Adagio Consultant to help you with this. We have done a number of imports into Adagio CQ from Web stores and it works quite well.
We have recently released our Link2SalesCQ which now handles mass transfers of Approved Quotes (Web Orders) into Adagio Order Entry. Our bench mark is about 80 quotes per minute on a busy network. We have transferred as imports into Adagio Order Entry, as many as 400 per import with over thousands line of details.
Works well. Please call when you are looking for a solution to transfer the quotes (approved) to Order Entry, if you have the volume.
Best,
Brian
