A target field mapping describes how one or more source fields are mapped to a target field. To describe a message mapping you must construct it out of individual target field mappings.
You must assign fields for your target field mapping to each other (see: Assigning a Field ). Use the data flow editor to edit target field mappings.
To be able to create a target field mapping you must first have loaded a source structure and a target structure in the mapping editor.
You can map individual fields to each other and change the structures in the process (see: Runtime Procedure ).
You can perform simple calculations, Boolean comparisons, text mappings, and other transformations by using the standard functions .
You can define user-defined functions in Java that you can use in exactly the same way as standard functions in the data flow editor.
You can duplicate subtrees in the target structure if source fields are to be mapped to different positions in a target field (see: Duplicating Subtrees ).
