Creating a many-to-one mapping

To create a many-to-one mapping, drag one source element to the target element, and then drag additional source elements to the transform.

For more information about many-to-one mappings see Many-to-one mapping and Transforms that create many-to-one mappings.

To create a new many-to-one mapping:

  1. In the mapping routine area, drag a source element to the target element, as you do when you are creating a one-to-one mapping (see Creating a one-to-one mapping).

    The mapping editor creates a one-to-one mapping between the source element and the target element and sets the transform to an appropriate default transform type (see Default transform type).

  2. Drag an additional source element to the transform.

    The mapping editor creates a connection between the additional source element and the transform and if necessary resets the transform to an appropriate default transform type.

  3. Repeat the previous step for additional source elements until you have included in the mapping all the source elements that you want to include.
    Note: Some many-to-one transforms (such as Subtract and Divide) require exactly two source elements, while other many-to-one transforms (Add, Multiply, Concatenate) allow two or more source elements (see Transforms that create many-to-one mappings).
