what does the expression n filter transformations do in Informatica Slowly growing target wizard?

dontknow

EXPESSION transformation detects and flags the rows from source.

Filter transformation filters the rows that are not flagged and passes the flagged rows to the Update strategy transformation

Expression finds the Primary key is or not, and calculates new flag

Based on that New Flag, filter transformation filters the Data

You can use the Expression transformation to calculate values in a single row before you write to the target. For example, you might need to adjust employee salaries, concatenate first and last names, or convert strings to numbers.
