根据下列步骤创建业务项实例。
将业务项映射到数据类型。
此数据称为业务项实例。
在项目视图中选择两个业务项。
在第一个页面中，如图13所示，选择业务项。
On the first page, as shown in Figure 13, select the business item.
业务项变为业务实体，等等。
需要在更详细的级别使用属性对业务项进行定义。
Business items need to be defined at a more detailed level with attributes.
您不可能将不同的业务项与不同的分支关联起来。
It is not possible to have different business items associated with different branches.
用于业务项实例的数据是静态的，并流经该模型。
The data used for the business item instances was static, flowing through the model.
业务项编辑器可以方便地将属性定义为数组类型。
The Business Item Editor makes it easy to define the attribute as an array type.
业务项用于捕获流经流程的信息类型或数据对象。
A business item captures a type of information or a data object that flows through the process.
如果业务项传输到流程，则映射会标记一个错误。
If a business item flows into the process, the map will be marked with an error.
要使用业务项实例，请将建模模式设置为中级或更高。
To use business item instances, set the modeling mode to intermediate or higher.
如果需要使用大量的不同业务项实例，这会非常有用。
This might be useful if you needed to use a large number of different business item instances.
结果证明，罪魁祸首经常是业务项与基本模式的组合。
More often than not, the culprit turns out to be the combination of business items and basic mode.
业务分析师将生成的XSD作为业务项导入。
Business analyst imports the generated XSD as business items.
输出条件总是希望获得另一输出条件的全部三个业务项。
The output criterion always expects all three business items in a single output criterion.
下面的步骤将介绍如何定义业务项（如图 1 所示）。
The following steps show how to define business items (also shown in Figure1).
除了使用业务项实例进行模拟以外，无法为流程提供输入。
No input was possible to the process, other than simulating with business item instances.
这样将创建没有关联业务项的连接，并创建一个额外的输入。
The connection is created with no business item associated, and an extra input is created.
业务项类似于数据结构，用于保存不同任务之间的数据交换。
A business item is similar to a data structure that holds the data exchange between different tasks.
在定义业务项中的数据类型时，早期版本中使用的术语针对技术用户。
When defining the data types within a business item, the terminology used in previous versions was targeted towards technical users.

Draw connections from data fields of the input business item on the left over to the output business item on the right.
在业务流程中传递的数据采用以xml模式描述的业务项的形式。
Data passed through the business process is in the form of business items which are described as XML schemas.
由于LDM 一般比业务项更加完整，具有更多字段或正确标准化的实体。
Because LDMs tend to be more complete than business items, with more fields or properly normalized entities.
业务模型中的两个连续任务可以使用不同的业务项作为输出和输入。
Two consecutive tasks in a business model may use different business items as the output and input.
附件是在流程级别添加的；您不能将文件附加到诸如角色和业务项等其他构造。
The attachment is added at the process level; you cannot attach files to other constructs such as roles business items.
