Epicor9.04MRP相关参数详细说明
-MRP计划
工厂-MRP
、物料--工厂
一、物料
•Min Lot Size-If the job requirement is below this number,it is rounded up.In a standard cost environment,this lot size should equal the costing lot size.For example,if four parts are required and the Min Lot Size is t to10,MRP creates a job for10parts,six of which are added to stock.
--指物料的最少生产批量。如果需求的数量少于最少批量，MRP将创建一个生产数最少批量
最少批量--
量等于最少批量的工单，多余的数量被收货至库存。
例如，物料的需求数量是4，最少批量设置为10，则MRP会创建一个数量为10的工单，其中多出的6个会被添加至库存。
•Max Lot Size-This is the maximum lot size for a job.For example,if MRP creates an unfirm job for100parts and the Max Lot Size is t to40,three jobs are created:two jobs for40parts and a third job for20parts.
最大批量--指物料的最大生产批量。如果需求数量大于最大批量，那么MRP将生成多张工单，每张工单的需求少于等于最大批量，直至它们的总和等于需求数量。
例如物料的需求数量是100，最大批量设置为40，那么MRP将创建3张工单，其中两张的数量为40，另外一张的数量为20.
有声读物网站>新竹园中学•Multiple-MRP rounds up the quantity to this number if the recommended job is for less than one multiple.The Min Lot Size and Max Lot Size values must be a multiple of the value in the Multiple field if a value exists.
倍数--指工单的生产数量必须是这个倍数的数倍（即工单数量可整除此倍数）。倍数被MRP用来决定工单将要计划生产的物料数量。MRP通常将其近似到最近的倍数。如果手动创建生产数量不是倍数数倍的工单，那么你将被系统警示，尽管仍然可以不修改数量保存。如果设置
了此参数，那么最少批量和最大批量必须是此参数的数倍。
例如，DCD-100-SP的需求数量是379个，倍数被设成是100，那么MRP将创建一个数量为400的工单（它是100的倍数）。

•Costing Lot Size
批量成本计算--指设置成本的计算批量，或者你可以这样理解，设置业务完成后可以生产多少件产品。工序的设置成本将除以此参数作为每个物料的设置成本。假设冲压工序，装模试模等设置业务的成本是200美元，每件产品的直接人工和直接原材料的成本是0.02美元。那么每件产品在该工序的单位成本是否等于200.02美元呢？当然不是，设置成本200美元全部由一件产品来承担显然是不合理的。假如该产品设置的批量成本计算是100，那么每件产品在该工序的单位成本等于200/100+0.02=2.02美元。

•Days of Supply-This field works with inventory items as well as with jobs.It contains the number of days that an inventory re-fill order or a production job covers.
供应天数--是一个库存物料重填定单应该覆盖需求的天数。这句话较难理解，好，转换成比较容易理解的，它的作用是将相同物料的在供应天数内的需求数量合并，生成未确认的工单或采购订单。从下边的例子你就可以很好地理解这个参数是怎样使用的：
假设你现在有张SO，DCD-100-SP出货行（Relea）分别为1月10日100件，1月12日150件，1月14日200件，DCD-100-SP的供应天数为3天，DCD-100-SP库存数量为0。那么MRP 将会创建多少张未确认的工单（忽略最少批量等其它参数）？3张？还是1张？正确答案是2张。为什么？
MRP计算逻辑，首先查找DCD-100-SP第一个需求的到期日（1月10日），然后再查找"供应天数+1"（3+1天，即1月10日、1月11日、1月12日、1月13日）天内是否还有需求，如果有的话，则MRP将这些符合条件的需求数量合并，然后生成未确认的工单。在这个例子中，1月10日的出货行和1月12日的出货行满足以上条件，所以它们的需求数量会合并在一起，而1月14日的出货行不满足此条件，所以它不能被合并。所以在这个例子中，MRP会生成2张未确认的工单，一张数量是250，另外一张数量是200。
二、物料
工厂--可用性
可用性//短期计划
、物料--工厂
Availability-The Availability ction controls whether this part is considered during the MRP process and if PO suggestions are generated.
•Process MRP-If lected,MRP process this part.
•Generate PO Suggestions-If lected,PO suggestions are procesd for this part.
可用性这两个参数比较好理解，略过。
Short Horizon Planning
短期计划
•Horizon Days-U this field to indicate a short horizon using the lot sizes in this ction for MRP processing rather than the part's standard lot sizes found in the MRP Planning ction of this sheet.If a job's due date is less than or equal to today plus(+)the short Horizon Days,the Min Lot Size and Max Lot Size information in this ction are ud during MRP Processing.All other planning parameters such as the lot Multiple remain the same.If this field is not populated,the lot size fields in this ction is ignored.

期限--使用此参数告诉MRP，如果工单的到期日少于等于（今天的日期+期限）的日期，那么就使用“短期计划”的最少批量、最大批量、供应天数进行MRP计算，而不是使用“MRP 计划”设置的参数计算（注意：倍数和批量成本计算仍然沿用这里的设置）。如果这个参数没有设置，仍然是0的话，则MRP会忽略本节的参数设置。
例如，DCD-100-SP在短期计划的期限设置是5天，今天是1月10日，DCD-100-SP的工单计划到期日是1月13日，那么MRP处理的的时候，会采用本节的设置参数进行计算。
•Min Lot Size-U this field to indicate the minimum lot size to u during the short horizon for MRP processing.If Horizon Days has been entered and if a job's due date is less than or equal to today plus(+)tho Horizon Days,this Min Lot Size information is ud during MRP Processing rather than the Min Lot Size in the MRP Planning ction of this sheet.If the Horizon Days field is not populated,this Min Lot Size field is ignored.

最少批量
validate最少批量--
•Max Lot Size-U this field to indicate the maximum lot size to u during the short horizon for MRP processing.If Horizon Days has been entered and if a job's due date is less than or equal to today plus(+)tho Horizon Days,this Max Lot Size information is ud during MRP Processing rather than the Max Lot Size in the MRP Planning ction of this sheet.If the Horizon Days field is not populated,this Max Lot Size field is ignored.
最大批量--请参阅第一点关于最大批量的解释
•Days of Supply-This field works with inventory items as well as with jobs.It contains the number of days that an inventory re-fill order or a production job should cover.What makes this different than the MRP Planning Days of Supply field is that this field is ud to record the short horizon order lead time for the part.

三、物料
工厂--计划
、物料--工厂such as
•Production Prep Buffer-The number of days that are required to prepare and create a job before it can be relead to the shop floor to start production.If this field is left blank and the Multi-Site module is installed,the value t in plant maintenance is ud.
--工单从下达到车间开始生产所需的天数。如果此处的值是0或你已安装了多生产准备缓冲
生产准备缓冲--
站点管理模块，那么将使用公司配置中设置的值。
例子：DCD-100-SP的“生产准备缓冲”的天数为4天，工单原先计划的开始日期是8月15日，那么再根据“生产准备缓冲”的天数，工单的开始日期需要提前4天，变为8月11日。
•Kit Time-For manufactured items,enter the time(in days)that it takes to kit the asmbled item. Kit time is only applied to manufactured items and is ud to calculate the demand date for any materials for the asmbly.The kit time is subtracted from the start date of asmblies that have no children asmblies.If this field is left blank and the Multi-Site module is installed,the value t in plant maintenance is ud.An example of this is the time it may take to package a monitor,mou and keyboard for a desktop computer that was asmbled.
merry me什么意思套件时间--套件组装（包装、配套）所需的时间，这个参数是用来计算组成套件所需物料的需求日期的，套件的类型必须是“生产”的此参数才会生效。组装成套件的物料的需求日期=套件的开始日期-套件时间。假如同时设置了“生产准备缓冲”和“套件时间”这两个参数，则这两个参数被累加作为工单计划开始日期提前的天数。
比如，DCD-100-SP的“套件时间”是5天，“生产准备缓冲”是10天，生产DCD-100-SP的工单计划开始日期是8月15日，那么MRP处理后，DCD-100-SP的套件组装日期为8月10日，开工日期为8月1日。
•Receive Time-In the ca of manufactured items,this is the number of days that are required to move the asmbly either to stock or to the next job.For manufactured parts,this buffer is added to the due date of the job.A good example of this is a commercial airplane manufacturer.They may need veral days to transport the plane to another facility to either stock the plane or continue to work on the plane and want the days in transit to affect the job's due date.In the ca of purchad or transferred parts,this is the time required to receive and inspect the part.This time is deducted from
