'Sizes' table (RetailEcoResSize) has 'Modified date and time' field, but lacks 'Modified by' field. This is a very informative field to be utilized with already existing field 'Modified date and time' and can be used to track changes made by end users (in cases where customer needs to know only the latest change) instead of database log setup. By using the 'Modified by' field customer is able to prevent the performance impact of DBL.
