Add Target Component
The next step is to add a target file called Library.xsd. To add the target file, click (Insert XML Schema/File). Click Skip when MapForce suggests supplying an instance file. Then click the header of the new component and drag it to the right of the two source components. You can always move mapping components in any direction. Nevertheless, placing a source component to the left of a target component will make your mapping easier to read and understand. This is also the convention for all the mappings illustrated in this documentation and the sample mapping files accompanying your MapForce installation.
At this stage, the target file only has structure but no data. The data will later be merged from the two source files and mapped to the target file.
