Mapping elements overview

The function sequence is run from top to bottom every time an XML document is transformed. Data values are fetched from linked input elements, processed, and then sent to linked output elements, constituting the output document.

Use these guidelines in defining the transformation sequence:

Create a transformation.

You create transformation by adding a sequence of function elements in the space between the input and output document trees.
Create links between document elements and function elements.
Create links between function elements.
Create links between variables or constants, and functions or documents elements.

Note: An output document is not mandatory, for example, in many inbound M3 messages, no output document is used because the data is stored in M3 by calling M3 APIs in the sequence. No response message is required.
