Subcontract Order

"Subcontracting”

即外包.该流程指采购方向供应商购买物品,但采购方或第三方需提供某些构件给组装商以生产所需物品.

在采购方提供构件的场景中,订单包含

- 一个标准的item category

- 在Vendor中填供应商号

除了产生订单,还会根据构件产生预留.见Tables.

在第三方这个场景中, 订单包含了

- 一个标准的item category

- 在Vendor中填第三方

- 组装商维护在delivery address标签中,对subcontracting vendor标记打勾





Item category: L (internal number 3)

- Document type需"允许"该Item category

- 标准系统中,PR,PO,Scheduling agreement允许Item category L

对于Scheduling agreement,只有做完schedule line(SE38)后才能执行BOM explosion

- RFQ和Contract也可以允许Item category L,需做如下变动 (Note 21697)

Copy the field selection keys PT0A(RFQ) or PT0K(Contract) to create the keys PT3A(RFQ) and/or PT3K (Contract) respectively.

但是该改变后仍无法执行BOM explosion, 也不会有component screen





Source Determination:

Only SC info record and SC scheduling agreement are taken into account

SC Stock:

- SC stock is part of the unrestricted-use stock. 可使用MMBE/ME2O查找.









- ME2O(Subcontracting monitoring list)提供了post component (541)和创建SD delivery的功能.

- Negative quantities can be allowed for SC stocks. [OMJ1]

BOM Explosion:

购买物料所需的组件,一般都是从BOM中带出.









有两个标签要特别注意:

Production Relevant:

Indicates that the item is relevant to the production process.
Items with this indicator are copied to the planned order, and the system calculates dependent requirements for them. When the planned order is converted to a production order, the system automatically copies these items to the production order. Mat. Provision Indicator:





Alternative BOM:

如果有几个可选BOM,则按以下规则选取(MRP 4 View)





Selection by quantity:

在BOM的抬头层,维护Lot Size





1. Selection by explosion date









2. Selection by production version 在同一个物料有多个不同BOM和供应商时使用.





将Alternative BOM分配给相应的Production Version, 在info record中输入相应的Production Version









New BOM Explosion:

如果物料在BOM中修改了,同时PO还未收货,可以重新运行一下BOM





Note: 16029 "New BOM explosion" - error message 06007

Component from another plant:

虽然BOM中的物料可以有多个工厂,但在BOM explosion时无法修改工厂..在Explosion时,都是参考建BOM时的工厂.

为了达成使用不同工厂的目的, 可以这么做[OMD9]









Transfer posting to SC stock:

可以通过以下方法将物料从unrestricted-use stock转移到SC stock (stock provided to vendor)

MB1B movement type 541 GI whse to subc.stck





COMP1原本有10个非限制库存,现变为8个+2个stock provided to vendor





接着,组件发料给组装商后,成品完工收货 MIGO (对于成品101收货,对于组件543 GI issue sls.ord.st.)









组件的库存也相应变化,之前的2件没了





MD04 is used to subsequent adjust for subcontracting

Note 110158

Material Planning:

Special procurement要选上





MRP跑完后,成品和组件都列入了计划









Special Topics: (待续)

可以把subcontracting PO分配给

- Make to order (individual customer, account assignment E)

- Make for project (Individual project, account assignment Q)

Note: 68908

If MARC-SBKDZ = 2







Tables:

The link pointer between purchasing document and BOM is RSNUM in EBAN or EKET

The component is in RESB under RSNUM/RSPOS.
