PurposeWith this component, you make a request to the warehouse to keep materials ready for withdrawal at a later date and for a certain purpose. This simplifies and accelerates the goods receipt process.A reservation for goods issue can be requested by various departments for various account assignment objects (such as cost center, order, asset, etc.).FeaturesThe purpose of a reservation is to ensure that a material will be available when it is needed. It also serves to simplify and accelerate the goods issue process and prepare the tasks at the point of goods issue.It is also important that reservations are taken into account by Material Requirements Planning (MRP), which means that required materials are procured in time if they are out of stock.Planning a Goods IssueYou can handle both planned goods issues and unplanned goods issues.You can also use reservations to plan goods receipts and stock transfers (see Planning Goods Receipts and Planning Stock Transfers and Transfer Postings). This section deals only with reservations for goods issues.Information in a ReservationIn a reservation, information is stored that is relevant for the goods issue and for materials planning, for example:What? (which material?)How much? (in which quantity?)When? (for which requirement date?)From where? (from which plant or warehouse?)To where? (to which recipient or customer?)A reservation document consists of a header and at least one item. The header contains general data about the reservation (creator, movement type, account assignment). The items describe individual planned movements (material, quantity, requirement date).You can create a reservation for exactly one purpose only; that is, in a reservation, you can only enter one movement type and one account assignment object (for example, a cost center).Reservation LevelThe system makes reservations at plant or storage-location level. For materials handled in batches, you can also create reservations at batch level.Manual and Automatic ReservationsThe R/3 System supports manual and automatic reservations. Manual reservations are entered directly by the user. Automatic reservations are generated automatically by the R/3 System. There are two types of automatic reservations:Reservations for orders, networks, WBS elements:When an order, a network, or a project is created, the components from the warehouse are reserved automatically.Stock transfer reservations:If reorder point planning is used at storage location level and the available stock on hand falls below the reorder point, the system generates a stock transfer reservation in the plant for the replenishment quantity.You cannot manually process automatic reservations. For example, it is not possible to change reservations for an order directly. You have to change the components in the order. The system then updates the reservation automatically.What are the Results of a Reservation?When a reservation is entered, the following events occur in the system:The system creates a reservation document, which serves as proof of the request.In the material master record, total stock and unrestricted-use stock of the material remain unchanged. Reserved stock is increased by the reserved quantity.In MRP, available stock is reduced by the reserved quantity. This is visible in the current stock/requirements list. The reservation causes an entry to be made in the requirements planning file.Displaying Reserved StockThere are two functions available for displaying reserved stock (also refer to Reporting in Inventory Management ):Stock overview at plant level:When you use this function, the system displays the total reserved stock for the material at plant level. From the stock overview, you can choose Environment ® Reservations to display a list of the reservations for the material.Current stock/requirements list:When you use this function, the system lists all of the open reservations for the material at plant level, along with the reserved quantity for each.

预留可以对应业务中的需求计划,预留中主要信息就是需求单位、需求物料、需求数量、需求时间。说得通俗一点,就是需求单位告诉仓库:我在某年某月某日需要XX物料N个。预留的英文叫reservation,用英文理解更贴切,非常像我们到餐馆或酒店的预订。 预留是否要日清日结,要看预留作为什么使用。如果预留用来作为需求计划使用,就没有“日清日结”这个概念,因为此时预留往往是对未来需求的体现,可能在实际需求日期前一个月就做好的需求计划,就好比你打电话到餐馆订位子,你订了一个星期后的4人位,怎么日清日结?另一种情况是在有的公司,将预留作为发货计划使用,比如发料员在系统中录入预留,作为对仓库保管员的发货指令,预留通常是体现当日内的发货需求,比如今日需要对哪几家单位发哪些物料,保管员按照预留进行出库,此时预留一般需要日清日结。 MD04可以在MRP清单中查看期间内的预留。运行MRP时,系统会根据当前库存,未清采购订单,即将到货的采购订单等等数据计算在未来的需求日库存能否满足需求数量,对于库存不能满足的部分就生成采购申请进行采购补货。举个例子:当前日期1月1日,此时有需求单位X提报一张预留:2月15日需要A物料100件。运行MRP时,系统检查到当前A物料库存30件,另有一张采购订单1月20日到货15件,另有一家单位Y在1月30日需要A物料20件,那么系统就预测出到2月15日库存将是30+15-20=25,不能完全满足需求单位X要的100件,运行MRP的结果就会生成一张75件的采购申请。
