Number Assingment for Customer Master Records　客户主记录的编号分配

Use

A unique number is assigned to every customer master record.You can use this number  to access the master record again later,or to refer to the customer when carrying out business transactions.
给每个客户主记录分配一个唯一的编号．以后可以使用这个编号来存取客户主记录，或执行业务事务时查询这个客户．

Inter and External Number Assignment
内部和外部编号的分配

The number for the customer master record can either be assigned internally by the system,or you can define the number yourself.The second method is called external number assignment.In the case of external number assignment,a number range that allows for alphanumerical number assignment can be defined.
客户主记录的编号可以由系统内部分配也可以由自己定义．第二种方法称为外部编号分配．在外部编号分配情况下，可以定义允许的字母数字编号分配的编号范围．

The account group determines whether internal or external number assignment is allowed for a customer master record.For account groups 0001 to 0005,for example,only internal number assignment is allowed in the standard version of the SAP R/3 System.
账户组确定分配给客户主记录的编号是内部编号还是外部编号.比如,账户组0001到0005,在SAP R/3系统的标准版本中只允许分配内部编号.

Nmber Range
编号范围

For every account group a number range is defined from which a serial number is assigned during internal number assignment.In the case of external number assignment the system checks whether the customer number entered lies within the defined number range.
对于每个账户组，可以从在内部编号分配中分配的连续编号中定义一个编号范围．在外部编号分配情况下，系统检查输入的客户编号是否在已定义的编号范围内．

A number range can be valid for different account groups.In the standard version of the SAP R/3 System the account groups for sold-to party,ship-to party,payer and bill-to party belong to the same number range so that the numbers for these master record are assigned cosecutively.You can use the number range to assign,for example,different nubmers to the head office and the branches.
一个编号范围可以对不同的账户组有效．在SAP R/3系统的标准版本中,售达方,送达方,付款方,收票方的账户组属于同一个编号范围,所以这些主记录的编号是连续地分配的.比如,可以使用编号范围给总部和分部分配不同的编号.

A customer's number is unique for all sales area and company codes. If you,for example,have created a customer master record for a customer in al sales area and create another customer master record for the same customer in another sales area,the system identifies the number and does not display the general data from the first master record for maintenance,since the general data exists already.You can also use the change and display funcitions to access the general data of the newly maintained views.
对于所有的销售范围和公司代码,一个客户的编号是唯一的.比如,如果已经在一个销售范围内为客户创建了一个客户主记录并且在其它销售范围为同一个客户创建了另一个客户主记录,系统标识该编号并且不显示保留的第一个主记录中的一般数据,因为该项一般数据已经存在了.也可以使用修改和显示功能来存取新维护的视图的一般数据.
