In the load planning work bench specific filters can be used, e.g. for a geographic region etc.
It is not possible to filter on sales lines that are reserved physically. It would be great if the query or view "Sum of quantities for an inventory dimension"would include a flag Reserved (i.e. no On order or Ordered reserved transactions exist for this sales line.)
This will make it possible to plan realistic shippable quantities when the load planning filter should only include lines that are fully physical reserved.
