I BASIS KNOWLEDGE AND SYSTEM NAVIGATION
基础知识及系统导航
1. Name two ways to start a transaction.
i. Dynamic Menu
ii. Command Field
1.请说出启动一个事务的两种方法。
使用动态菜单选择
使用命令字段输入事务码
2. Why do you create user-specific parameters?
i. They supply defaults to R/3 fields. If a field is indicated, the system automatically fills in default value. Depending on the field definition, the entry can also be replaced with a value entered by the user. (Concept of PARAMETER ID)
2.为什么要创建用户指定参数呢？
提供了默认的R /3字段信息。如果一个字段标示了值，在使用过程中遇到这个字段，系统会自动填充默认值。基于字段定义，该项也可以由用户输入替换默认值。（基于参数ID概念）
3. Name the three different kinds of messages in the R/3 system. What is the difference between them?
i. A message can have five different types. These message types have the following effects during list processing:
ii. A (=Abend):
a. The system displays a message of this message type in a dialog window. After the user confirms the message using ENTER, the system terminates the entire transaction (for example SE38).
iii. E (=Error) or W (=Warning):
a. The system displays a message of this message type in the status line. After the user chooses ENTER, the system acts as follows:
b. While creating the basic list, the system terminates the report.
c. While creating a secondary list, the system terminates the corresponding processing block and
keeps displaying the previous list level.
iv. I (=Information):
a. The system displays a message of this message type in a dialog window. After the user chooses ENTER , the system resumes processing at the current program position.
v. S (=Success):
a. The system displays a message of this message type on the output screen in the status line of the currently created list.
3.请说出三种不同类型的系统消息，并指出区别。
系统提供五种不同类型的消息，这些消息类型在使用中有如下影响.
A(= ABEND）：
系统会在这个类型中显示一个对话窗口消息，回车确认后，将终止整个事务运行（例如SE38）。
. E (=Error) or W (=Warning):
在状态栏显示一个错误消息，回车后执行如下：创建的基本清单同时系统终止清单列表。创见一个二级清单列表同时，系统将终止相应的处理块，并显示前一层次清单。
I (=Information):
系统显示一个消息对话窗口，选择回车后，系统恢复处理在当前位置的程序应用。
S (=Success):
在当前清单列表屏幕的状态栏显示一个消息，表示执行成功。
4. What is a data dictionary or repository?
i. Central catalog that contains the descriptions of an organization's data and provides information about the relationships between the data and its use in programs and screens.
ii. The data descriptions in a Data Dictionary is also called metadata, i.e., data that describes other data.
iii. The ABAP/4 Dictionary stores system-wide data definitions. When you create a new data definition, the Dictionary tool does all the processing necessary to create the definition. You can use the Dictionary tool to look up the "definition" of objects in your R/3 System.
4.什么是数据字典或原数据？
是一个核心类别目录，包含了组织数据描述信息，提供数据和它使用的程序、屏幕之间关系的相关信息。
在数据字典中,数据描述也被称为元数据，即描述其他数据的数据。
ABAP字典存储了全系统数据定义。创建一个新数据，定义字典工具是必须的。你可以用字典工具查找系统中的对象的“定义”。
