You need to generate a hierarchy object as an XML string to pass it as an input argument to a Siebel business service method.

The following figure shows a sample mapping that uses a hierarchy object as the input:

The sample mapping shows a Siebel Business Service transformation that takes a hierarchy object as the input and converts it into an XML document. The hierarchy object is passed as an XML string from the source to the Siebel Business Service transformation. This transformation converts the input hierarchy object into an XML document and generates the document as an XML string.
