Using an IS Document Type to Specify Service Input or Output Parameters
You can use an IS document type as the set of input or output parameters for a service or specification. If you have multiple services with identical input parameters but different output parameters, you can use an IS document type to define the input parameters rather than manually specifying individual input fields for each service.
If the service uses an IS document type from a different package, you must set up a package dependency. For more information about package dependencies, see About Package Dependencies.
When an IS document type is assigned to the input or output of a service, you cannot add, delete, or modify the fields on that half of the Input/Output tab.
* To use an IS document type as service input or output parameters
1. In the Package Navigator, double-click the service to which you want to assign the IS document type.
2. Click the Input/Output tab.
3. In the Input or Output field, type the fully qualified name of the IS document type or click to select it from a list. You can also drag an IS document type from the Package Navigator to the box below the Validate input or Validate output check boxes on the Input/Output tab.
4. Click File > Save.
