As per the given requirements, the following masking rules need to be applied to the Targets_ID field:
The IT team is planning to use a credit card function mask to achieve this.
A credit card function mask is a built-in data masking function in Azure SQL Database that replaces all but the last four digits of a credit card number with "X" characters. This function is not suitable for the given requirements because it only masks a specific type of data (credit card numbers) and does not allow for custom masking rules to be applied.
Therefore, the given solution does not meet the requirements and does not achieve the goal of masking the Targets_ID field according to the specified rules. The IT team will need to use a custom masking function or solution to achieve the desired result.
