今天在创建采购订单时保存不了，提示Client没有指定Logical
System，记起前面创建Client 100时，并没有定义Logical System。
什么是Logical System？做什么用？
'Logical System' is used to identify an
individual client in a system, for ALE communication between SAP
systems.
What is ALE Converter?
An Application Link Enabling (ALE)
converter acts as a bridge between SAP applications and another
application. It receives Intermediate Documents (IDocs) from one or
more of SAP applications instances and makes the converted data to
that application. It also takes data from an external application,
convert it to the appropriate IDoc format, and send it to SAP
applications.The communication method between the SAP applications
and the ALE Converter must be transactional RFC
(tRFC).

IDES 800的数据太多了，做一个Client
Copy，需要处理27000多个表，可能会又7、8千万左右的数据量！因为目前进度50%不到，Copied
Lines是26,030,610，Deleted Lines是3,407,922。没办法，想以800为基础，参照Help
Online学习，又怕把这个Client给弄的跑不下去。
昨天用的前台跑，运行不多久，大概处理了6000多个表，1千万左右数据的时候，就出错了，大致是说Oracle回滚段空间不够。具体信息如下：

SAP系统配置比较复杂，初学者在练习过程中可能会更改IDES系统的配置、数据等，而无法还原。因此常用的方法是新建一个Client，从一个已有的Client把配置、数据等Copy过去。这样在新的Client下操作时，就算把这个Client破坏了也无所谓。

2.1 SAP
Authorization Concept
The SAP authorization concept is based upon the logical relationship between a user ID and the range of system authorizations with which it can be associated. The architecture of the authorization system is based upon the utilization of several individuals but related logical components: Profiles, Objects, Fields, and Authorizations. The user ID refers exclusively to profiles. Each profile grants a set of specific system access authorizations to user. Figure 2 illustrates the hierarchical authorization concept in SAP.

Finally I have finished installing the
system. It spent me a whole day!
All things went well during the
installation by following the instructions. One notes: when
installing the database instance, there's a step to select the 'CD
KERNAL' package location. The package is just located in a 40G
removable disk with the disk driver 'I'. After I chose the disk 'I'
in the CD browser dialog, the cursor went wating status, then I
kept waiting. An hour later I felt something's wrong and closed the
CD browser dialog. It didn't interrupt the installation progress.
So I coped the package path derectly into the package location
input, and went throug next step without any errors. It just waste
me an hour!
When logged on after installation,
there's always the illegal memory read & write errors. In some
of the operations the error messages in the system status bar was
such as 'incorrect loca
