The Weighted Average transformation is a passive transformation that reads match scores from multiple matching operations and produces single match score.
You can apply a numerical weight to each score that enters the Weighted Average Transformation. A weight is a value between zero and 1. You can edit the weight applied to each input score to increase or decrease its contribution to the output score. Apply weights that reflect the relative importance of each data column in the duplicate analysis.
Use the Weighted Average transformation when you add Comparison transformations to a mapping or mapplet.
You also can assign weights in a Match transformation. Use the Match transformation to configure matching strategies and assign weights in a single transformation. You can embed a matching mapplet in a Match transformation.
