The following document explains how to associate a location with a particular picking ticket.
Select the location module.
When creating the location, on the right-hand side there is the option to select the transaction type.
For this example, the location that is being selected is for picking, so default picking is selected.
When creating a picking ticket, there is a location column in the line item grid where you can select the picking location for each line item. The list will be based on the available stock at the location that matches the ship from address on the pick ticket.
While in edit mode, click on the field corresponding to the line item and select the appropriate location.
Once the appropriate location has been selected, click on the save button. The system should set the address of the pick transaction to match the address of the first assigned location.
Once the location has been entered, you can issue the pick ticket. However, some situations will be prevented by the system.
Finally, once issued, the ship from of the transaction cannot be changed.
