In the FDM, I have a requirement to mask the date column in a specific format of adding one month and one day to the existing DOB. When I add 2 to 3 conditions, it is working fine. When I add more conditions(as i need to consider leap year, non leap year, month end, etc) it is doing double masking. Please help me arrive at a optimal solution(without restartability as client is not ok to add any additional column in the exising table). Thanks in advance.
