Task business data typically defines the inputs and outputs of a task, and can be added to a task as an Integration Server document type or as a custom business data field.

You have the opportunity to specify the document types and fields you want to use at any time after you create a task. You can also modify the data passed into and out of the task. For more information, see About the Task Data Envelope and Modifying Task Information in the Task Envelope Data Flow.

You can add business data to a task in the following ways:

The input fields of a document type (also known as the input signature) define the information that the task expects for input; the output fields (known as the output signature) define the information that is passed on by the task to the next step in the process. A stand-alone task may not require any output elements.

For example, your document type may contain task input elements for "name," "price," and "quantity." Similarly, a document type may define output elements such as "accept" and "escalate." Or, you might include both input and output elements in a single document type.

You can create Integration Server document types in Software AG Designer using the Service Development perspective. For more information about creating a document type, see webMethods Service Development Help.
