Configure mappings using the Compose Mapping Expression editor. Mappings are available only to message-targeted mapping nodes.
Alternatively, from the Outline view, select the value that you want to edit and right-click. Select Edit Mapping from the pop-up menu to open the Compose Mapping Expression editor.
For these nodes, the existing method of updating multiple columns in a row is still supported. However, you can map these nodes, as well as the Warehouse node, as a one-to-one mapping. This enables you to merge multiple mappings into a single row in a table, or split a mapping into multiple one-to-one mappings (one for each row).
