Rules and Guidelines to Map Elements to Output Ports

Rules and Guidelines to Map Elements to Output Ports

Review the following rules when you map elements in the method output hierarchy to output ports:
  • The method output element and the output port must have compatible datatypes.
  • You cannot map an element to more than one output port in a group.
  • Each output port must have a valid location, unless the port is a pass-through port.
  • If you drag a multiple-occurring child element to an empty output port, you must relate the group to other output groups. When you select a group, the Developer tool creates keys to relate the groups.
  • When you drag a multiple-occurring element into a group that contains the parent element, you can configure the number of child element occurrences to include. Or, you can replace the parent group with the multiple-occurring child group in the transformation output.
  • If the web service produces a JSON document, ensure that xmlRoot is the first node in the response hierarchy. If xmlRoot is not the first node for a web service with JSON response, null values may appear in the output ports.
