In a recent project we added a new column to the transport planning transaction showing the percentage of the order that is already available as stock. It is a very simple enhancement and users like it a lot. The logic is very simple. We appended a new field to the display structure and used EXIT_/SAPAPO/SAPLVS_VSGUI_005 to fill the data. For each entry we get the pegged stock with function /SAPAPO/OM_ORDER_GET_DATA. This indicator is good because you can open the transport plan and identify the loadings that may become problematic. And you can optimize the transport plan allowing earlier delivery only for orders that already have 100% stock.
