Safety stock

Specifies the quantity whose purpose is to satisfy unexpectedly high

demand in the coverage period.

The risk of shortfalls is reduced by having a safety stock.

Procedure

With manual reorder point planning, you can enter a value in the

material master record. However, it is merely for information.

With automatic reorder point planning and forecast-based planning, the

system determines and adjusts the value automatically for forecasting

purposes.

MRP 跟安全库存存在一定的联系。

一．第一次创建物料

如： R999-100 这个物料是我们刚创建的

Safetty Stock： 100 PC

我们用T-Code: MMBE / MB52

<shape id="_x0000_i1026" style="WIDTH: 415.5pt; HEIGHT: 175.5pt" type="#_x0000_t75"><imagedata o:title="" src="file:///C:%5CDOCUME~1%5Cwei_zhu%5CLOCALS~1%5CTemp%5Cmsohtml1%5C01%5Cclip_image003.png"><font face="Times New Roman" size="3"></font></imagedata></shape>

因为物料是刚创建，肯定是没有库存， 所以库存 是 0 .

通过一系列T-Code: MK01 创建供应商， T-Code: ME11 创建物料清单

完成上面的操作后，我们可以通过 T-Code: MD03 创建采购需求

接着 T-Code: MD04 Run MRP ， 我们可能到planing order 已经被创建出来，物料需求就等库存 100 PC.

以上是为了满足 Safety Stock 保持 100 自动创建物料需求 Run MRP.

二.当库存被消耗完，低于安全库存

假若库存现在 Material Number: R999-100 Qty: 100 PC

现在我们用MIGO ， Good Issue , Others , Moventy Type: 502 做一次发货，使库存数量低于安全库存，这里我们将库存数库成 0 PC.

T-Code: MB51

<shape id="_x0000_i1027" style="WIDTH: 414.75pt; HEIGHT: 78pt" type="#_x0000_t75"><imagedata o:title="" src="file:///C:%5CDOCUME~1%5Cwei_zhu%5CLOCALS~1%5CTemp%5Cmsohtml1%5C01%5Cclip_image005.png"><font face="Times New Roman" size="3"></font></imagedata></shape>

这里我们再做 MD03 创建物料需求计划， MD04 Run MRP. 可以看到新的planning Order 又产生了.

<shape id="_x0000_i1028" style="WIDTH: 415.5pt; HEIGHT: 167.25pt" type="#_x0000_t75"><imagedata o:title="" src="file:///C:%5CDOCUME~1%5Cwei_zhu%5CLOCALS~1%5CTemp%5Cmsohtml1%5C01%5Cclip_image007.png"><font face="Times New Roman" size="3"></font></imagedata></shape>

三． 我们也可以通过 加Forecasting 的方法来产生Run MRP请求

T-Code: MD64 给物料加 Forecasting

<shape id="_x0000_i1029" style="WIDTH: 343.5pt; HEIGHT: 181.5pt" type="#_x0000_t75"><imagedata o:title="" src="file:///C:%5CDOCUME~1%5Cwei_zhu%5CLOCALS~1%5CTemp%5Cmsohtml1%5C01%5Cclip_image009.png"><font face="Times New Roman" size="3"></font></imagedata></shape>

接着： T-Code: MD03

MD04

我们可以看到，也产生了Run MRP 物料需求计划.
