A delivery document is-similar to the sales order document In that the settings control how delivery is to be Carded out at the highest level and has a delivery item Category assigned to it. The SAP System can only copy items of a sales document to delivery if they have schedule lines. The control of the schedule lines depends on the schedule line category which is determined by the Item Category and MRP type. 2. I want to add something like schedule line converted into item line in the delivery document. Schedule line mainly gives u the data related to delivery date and quantity but schedule line gives u the full detail like hip-to-party, shipping point, picking a date, etc.
