This activity enables you to create an XQuery transformation that maps source elements to target elements (for example, incoming purchase order data into outgoing purchase order acknowledgment data).

Figure A-50 shows the XQuery dialog in BPEL 2.0. This dialog enables you to perform the following tasks:

• Define the source and target variables and parts to map.

• Specify the XQuery mapper file.

• Click the second icon (the Add icon) to the right of the Mapper File field to access the XQuery Mapper for creating a new XQuery file for graphically mapping source and target elements. Click the Edit icon (third icon) to edit an existing XQuery file.

For more information, see Creating Transformations with the XQuery Mapper.
