This button appears in two places on the Pack Confirmation form; on the right side of the form and at the bottom left.
Click the button on the right side of the form either to create packages and add the selected items/serial numbers to the packages or add the selected items/serial numbers to the package defined in the Package field. When you click this button, records appear in the Packages grid for each package that was created. The packages are given a numeric identifier beginning at 1 and increasing by 1 for each new package added. The items/serial numbers that are added to the packages show in the items and serial numbers grids that appear next to the packages grid.
Click the button at the bottom left of the form to add packages to other packages.
