PATH:

Logistics – General->Logistics Information System (LIS)-> Logistics Data Warehouse->Data Basis->Applications->Maintain Self-Defined Applications

目的: 定义应用程序范围,一般来说,不需要定义.系统已经为各个application 对应相应的模块及对应的TABLE.

Logistics – General->Logistics Information System (LIS)-> Logistics Data Warehouse->Data Basis-> Field Catalogs-> Maintain Self-Defined Field Catalogs

目的: 定义字段目录,把你所需要的字段做成相应的目录,以便你进行选择.

Characteristics catelog（特征目录，比如工厂,物料,采购组织）

Key Figure Catalog（关键表目录比如采购订单数量, PRICE）

Date catelog（时间目录比如交货日期,建立日期等）

如建立如下:

Logistics – General->Logistics Information System (LIS)-> Logistics Data Warehouse->Data Basis-> Information Structures-> Maintain Self-Defined Information Structures

激活.

维护UPDATE GROUP,目的让每个 update group 对应相应的application

当实际需要从源字段到目标字段的逻辑比较复杂的逻辑时，你还可使用requirement和Formula。 Requirement表示此需求的条件满足时才将源字段内容映射到目标字段，formula定义的逻辑将数据更新到目标LIS表,如果requirement不满足,公式里的逻辑不被使用，维护Requirement（Tcode:MC1B）维护公式(Tcode:MC1D)

为什么这个update group要选择SAP,原因在于下面的解释.

然后产生,再去激活 update .

V0 = No Update

V1 = 同步

V2 = 异步(文档更新与统计更新为两部分,只要文档更新成功,不管统计是否成功这笔交易都算成功)

V3 = 异步(但是需要用以下图去更新,即在某段时间统一更新,需设定background Job)

You determine when information structures are updated. You have the following options:

• Synchronous update (V1 update)

The statistics update is carried out synchronously with the document update.

However, if an error occurs when updating, and statistics update terminates, then the corresponding documents are no longer available and must be reentered.

• Synchronous update (V2 update)

In this case, the document update and the statistics update are separate. A termination of the statistics update has no influence on the updating of the documents in the operative application.

In addition, you have the option of executing the document update and the statistics update on two separate systems.

• Collective update (V3 update)

Updating type V3 (collective update)is a special type of asynchronous update. The update tasks are collected and then executed together in a background job. This means that you can specify when the statistics are to be updated.

V3 updates thus allow you to move statistic updates to times when there is less load on the system, for instance at night. The collective nature of the process also means that the number of write operations to the database are considerably reduced.

These two factors can improve general system performance noticeably.

Obviously, if it is necessary the statistics are completely up-to-date, you should not use V3 updating.

The document update and the statistics update are also separate here. A termination of the statistics update also has no influence on the updating of the documents in the operative application.

However, contrary to the V2 update, the V3 collective update must be scheduled as a job.

There are special considerations to be taken into account when using collective (V3) updating. When activating collective updating, check the following features.

• No update means that updating is switched off.

当采用U3异步更新(请参考OMO1,数据更新U0-U3),在后续时段比如在期末才一致性将数据更新到LIS表,随着计算机的性能提高,通常都会使用U1在线更新。

建议选择 synchronous updating (1)

当设定完这些后系统仍然不会UPDATE,你还需要去看你的Update rule中的update Group是否与application关联

这里设定了,这些的UPDATE会跟 Update group SAP相关.

如上图,update group= sap ,如果你在update rule 的时候,UPDATE GROUP不选择SAP的话,则系统仍然不会进行UPDATE.
