To issue goods through the picking list is a similar procedure as the procedure to issue goods through a sales order. However, these two procedures are mutually exclusive, if using the picking list you cannot use it in combination with the sales order (see Adding orders through picking list), because the picking list takes over the function of the order in the delivery phase of goods (see the process Links to dispatching and managing back-orders).

The Issue through Picking List checkbox in the warehouse panel of the Subjects register determines whether or not a warehouse uses a picking list a picking list.

2. warehouses the picking list cannot be used at - to link sales order with issued invoice adding orders through picking list function is used. The function offers a list of orders that can be selected for the delivery. Each line of the invoice created in this way can be changed if required (quantity, price...). The use of the picking list in these warehouses is not allowed. However, possible is manually adding of invoice lines without a link to the sales order or the picking list.
3. warehouses the picking list is used at - to link sales orders to the issued invoice an intermediate phase, a picking list, is used. First, sales orders are moved to the picking list, and then of the picking list an issuing invoice is created. Movements can be made in two ways:
   • by using the adding order through the picking list function, however, the procedure of the function is different if issuing goods from warehouses for which the use of a picking list was determined  (see Adding orders through picking list),
   • directly from the picking list | Create document panel (see Issue of goods through picking list).

Picking list lines that refer to the same line in an order will not be merged while being added to the invoice, these lines will be added individually. This is necessary to maintain connectivity and transparency of the picking list and the packing slip.

Individual lines of an invoice created this way can also be changed (quantity, price...). However, the quantity entered in the issue document should generally be less than the quantity in the picking list. If you try to issue a quantity greater than the quantity of the picking list, the program reports an error (see The quantity to be dispatched is less or equal to the quantity on the picking list! Maximum quantity is (x)!).

If the quantity on the issue document is less than the quantity on the picking list, when you save the document, the program will create a new picking list line with the difference and the deliver-by date of the original picking list line (see Picking list and changing quantities in an issue document).
