    Yes, there is an implication: Normalize calculates the scaling factors based on the actual data. If you perform a simple range transformation, Normalize is not affected, if the replenishment values are inside the original data range. However, if you perform a Z-Transformation, the scaling factors may be influenced by the values that you add to your data.

    Best regards,
