Bonjour Christopher, Now i got your need clearly I can announce you that delphix still can help you, identify the columns with issue and do it without any pain. The action plan is the following: 1/ create a masking job without taking any action to normalize the bad columns 2/ run the masking job on the column >> normally you will end up with the columns responding to masking criteria masked and the bad once will not be masked Now to identify the bad column 3/ create a certify job and run it on the column, it will let you know which one aren't responding to the masking algorithm criteria.

Hi Chris, You're right on this. One idea without knowing the structure of you data, try to mask the column first using the same masked value. ex AZE23RRT AZE00RRX in this example I’m assuming masking chars of position 4 and 5 with 0 and the 9th chars with x Later, to identify the columns that are out of the scope you have to supply a sql order that shows the lines that doesn't have 00 in 4 and 5 position and X in the 8th one.Hope you've got the idea.
