Hi Monique,
It is possible to print either a picking slip or an order confirmation with quantity shipped, and without creating an invoice. To do this, you must edit the OE Company Profile and enable the option 'Quantity shipped on orders'.
With this option enabled, you can create an order and include some quantity shipped. When it comes time to post the order, you will notice that the Order selection is now active as well as the Invoice selection. You need to select the Order choice in order to keep this as an order, without creating an invoice.
If this will be a typical way of creating orders (with quantity shipped, but not initially creating an invoice at the same time), you may also want to select the Company Profile option to 'Default post to order', which when posting an order with some quantity shipped, that Order choice above will be the default, rather than Invoice.
When you are ready to ship the stock and invoice the order, you then choose Invoice when posting the document, instead of Order.
