A map can only contain one input and output structure, but structures can be combined to use several input and output files.

Talend Data Mapper uses input and output expressions (I/O) to handle multiple data sources. If you use a Job with multiple input or output components linked to a data mapping component, these expressions are automatically added to the map.

For more information about these expressions, see Input/Output expressions.
