Consumption Strategies and Logic

消耗的策略及逻辑

Purpose 目的

In the consumption process, the system compares planned independent requirement quantities and dates with actual customer requirements. The consumption process is defined for every planning strategy in Customizing for Demand Management by combining a requirements type from Demand Management and a requirements type from sales order management. This step means that the requirements type entered when maintaining planned independent requirements is compared to the customer requirements type specified in Customizing.

在消耗处理中,系统用计划独立需求的数量及日期与实际的客户需求作比较。在后台定制作业中的每一个计划策略中定义了消耗策略的处理流程,需求管理中的需求类型和销售订单中的需求类型一起决定消耗策略。维护在计划独立需求中的需求类型和在定制作业中为客户指定的客户需求类型要做比较。

Prerequisites 准备

You must maintain the consumption mode in the Material Master Record (MRP) screen or in Customizing for Demand Management. The consumption mode determines whether consumption is to be carried out as backward or forward consumption, or whether both consumption types are allowed. In backward consumption, the system looks for the planned independent requirement quantity that exists directly before the sales order.In forward consumption, the system looks for the planned independent requirement quantity that exists directly after the sales order. You also need to maintain the consumption period in the MRP screen or in Customizing for Demand Management. The consumption period (forward or backward) is specified in workdays and is valid from the current date. Sales orders, material reservations, and dependent requirements then consume the planned independent requirement quantities that lie within the consumption period and after (for forward consumption) or before (for backward consumption) the requirements date.

你需要在物料主记录的MRP视图中维护物料的消耗模式,或在需求管理的后台定制中维护。消耗模式决定消耗是向后消耗还是向前消耗,还是向后向前都允许。在向后消耗中,系统寻找在销售订单以前存在的计划独立需求数量进行消耗。在向前消耗中,系统寻找在销售订单之后存在的计划独立需求数量进行消耗。你还需要在物料主数据中的MRP视图,或需求管理的后台定制作业中维护消耗的期间。消耗期间(向前或向后)指定从当前日期起的有效工作天数。销售订单、物料预留和相关需求都会消耗在需求日期之后(向前消耗)或在需求日期之前(向后消耗)的位于消耗期间内的计划独立需求。

Process Flow 处理流程

 

The customer requirement consumes the planned independent requirement quantity that either directly precedes or follows it. If the planned independent requirement quantity directly preceding the customer requirements does not cover the customer’s requirement, then the system looks for the next closest planned independent requirements in the future or past.

客户需求消耗计划独立需求的数量。如果计划独立需求的数量向前消耗时不能满足客户的需求,系统会寻找最近的一个计划独立需求去消耗。

During this process, the system refers to the consumption periods maintained in the material master or in Customizing for Demand Management (see above). The consumption periods determine the intervals (for backward or forward consumption) within which customer requirements consume planned independent requirements. Customer requirements that lie outside the consumption period are not consumed.

在这个处理过程中,系统会参考维护在物料主数据,或在需求管理的定制作业中的消耗期间。消耗期间决定客户需求消耗计划独立需求的范围。位于消耗期间之外的客户需求不被消耗。

If no consumption periods have been maintained, you can only consume requirements that are planned on the same day. The allocation of customer requirements to planned independent requirements is carried out dynamic. This step means that if sales orders or planning is rescheduled, the allocation is deleted and redefined.

如果没有维护消耗期间,你只能消耗那些计划在同一天的需求。客户需求到计划独立需求的分配是动态的。这就意味着如果销售订单或计划被重新计划了,分配会被删除并重新分配。
