Select this option to display the Choose lines to exclude from allocation grid, where you can exclude specific lines from the allocation. This option is not available if no charges have been set up. The grid includes only those lines that match the criteria in the Allocate charges to lines and Stocked fields. For example, if you select Positive lines in the Allocate charges to lines field and select the Stocked option, only lines that are both positive and stocked are displayed in the grid. Any lines for which the full quantity has already been received are not displayed. You can exclude specific lines from allocation by clearing the Include option for each line that should be excluded. To exclude specific lines from allocation, make sure that the grid is displayed when you click OK.
