    According to the MySQL site:

    The DEFAULT value clause in a data type specification indicates a default value for a column. With one exception, the default value must be a constant; it cannot be a function or an expression. This means, for example, that you cannot set the default for a date column to be the value of a function such as NOW() or CURRENT_DATE. The exception is that you can specify CURRENT_TIMESTAMP as the default for a TIMESTAMP column.

    So:

    alter table `RMS`.`transactionentry` 
    
    change `Date` `Date` date default CURRENT_TIMESTAMP NOT NULL
    

    should work. Your issue was you're making it a string by placing quotes around it.
