[RameshreddyE]

I have gone through multiple use cases for Transform scripts, Source script and Run script, But unable to understand that which script we use for which requirement or use case. So can any one help me in this.....

I believe you are referring to scripts available during transformation

1) field map script -used to handle field map values

2) Run script option available in transform map - similar to onBefore

3) Transform scripts (onBefore, onStart, onAfter, onComplete) etc - different types based on diff requirements

good explanation here on sequence
