Adding Data Mapper to a project opens a component window. Data Mapper includes two IN-Ports and one OUT-Port. You can map each input data stream to the OUT-Port structure.
Using the Data Mapper
Add the component to the project and connect the ports of the component to adjacent components.
Click the Rule button in the Property section to open the Data Mapper window.
Enter a mapping between IN1-Port and OUT-Port. Use the Enforced Output Value to assign computed expressions to the OUT-Port attribute.
Enter a mapping between IN2-Port and OUT-Port. Use the Enforced Output Value to assign computed expressions to the OUT-Port attribute.
Create the mappings for IN1-Port and IN2-Port.
The Data Mapper window contains of two tabs, IN1 and IN2 (located at the upper right corner of the mapping area). IN1 tab allows to map the upper IN-Port to the OUT-Port. The IN2 tab contains the mapping between lower IN-Port and the OUT.-Port.
The IN1 and IN2 tabs are located in the upper right corner of the component window.
You can create the mapping either automatically by using the Create mapping by order or Create mapping by name button. Alternatively you can draw the mapping lines manually.
