Defining Complex Data Types (SAP Library - SAP Exchange Infrastructure (BC-XI))

Defining Complex Data Types

Procedure

Create a data type in your namespace in the design maintenance of the Integration Builder (see: Creating a New Object).

Choose the Definition tab page. The XSD editor automatically selects the category Simple Type when you create a data type.

To insert a subnode, call the context menu for the root element and choose either Insert Subelement or Insert Attribute. This is only possible if the root element has not been assigned a type.

Note

If a type has already been specified in the Type column, you can delete it again by selecting the type with the cursor, deleting the selected text by choosing the Del button, and then confirming the change by choosing Return.

The type then automatically changes to Complex Type. Using the context menu, insert further elements and attributes to build up the structure of your new complex type. Note the following:

Unlike elements, attributes cannot have subnodes. Therefore, you can build up structures using elements, but use attributes to specify additional information for an element in a message. Also see: Elements and Attributes.

Subelements can only be inserted for elements that do not have a type.

If a single substructure becomes too complicated, you are recommended to use multiple small data types instead, especially when these can then be used elsewhere. To reference other data types, choose Search Help in the list box for the Type column.

As long as the element concerned is not the root element, you can change the field name by triple-clicking it.
