Use this dialog box to automatically reserve many order lines as a batch, as opposed to doing it line-by-line. The reservation will be performed on all the order lines on the chosen site, up to the date specified. The reservation will be done according to the automatic reservation logic i.e. according to rules configured for FIFO, zone ranking, handling units etc. This is described in detail in the About Reservation Management. You can either create a customer order reservation directly, or schedule the task that will be run periodically as a background job.
