* You specify how the system is to determine the lot size by 选择ing one of the lot-sizing procedures in the material master record. The system uses the result of the lot-size calculation as the 数量 for 生产 or procurement of the material. You can display and change this procurement proposal. You can also specify additional restrictions when maintaining the material master record which the system takes into account during lot sizing. These restrictions include: Minimum lot size You use the minimum lot size to define a minimum procurement 数量 per lot. Maximum lot size You use the maximum lot size to define the maximum procurement 数量 per lot. Rounding value If you define a rounding value the procurement 数量 must be a multiple of this value. Rounding Profile * * * * * * * * * References for creating the demand program You can use the following references for creating the demand program: Sales plan or 生产 plan of standard SOP Any key figure 计划 in flexible planning 计划 in非独立需求uirements versions of the same material or of another material Material forecast Original plan You can instruct the system to distribute the total reference 数量 according to a period split of your choice during the copy action. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * The customer 需求 consumes the 计划 in非独立需求uirement 数量 that lies either directly before it or directly after it. If the 计划 in非独立需求uirement 数量 that lies directly before the customer 需求s does not cover the customer’s 需求, then the system looks for the next closest 计划 in非独立需求uirements either in the future or the past. 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 需求s consume 计划 in非独立需求uirements. Customer 需求s which lie outside the consumption period are not consumed. * * In MPS, the master 排程
