You can map an input port to one node in the operation fault hierarchy. The input port and the node must have compatible datatypes.
You can map ports from one input group to nodes in the same hierarchy level in the operation fault.
You can map different ports from one input group to nodes in different hierarchy levels in the operation fault.
You must map input port data to the keys in the operation fault hierarchy. Any port that you map to a key must be a string, integer or bigint datatype. Map data to the keys in all levels in the operation fault above the hierarchy level that you are including in the SOAP message. Include the foreign keys for all levels above and including the level you are mapping.
You can map multiple input ports of different datatypes to a key. When you click the
field for a key, you can reorder the input ports or remove one of the ports.
