@RameshreddyE

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

Validating the order of execution for transform map scripts

If my response helped please mark it correct and close the thread so that it benefits future readers.

@RameshreddyE Here are some explanations.

Run Script: Run script is usually used in case of a workflow activity to perform CRUD (Create, Read, Update, Delete) operation on a table. Run script only runs inside a workflow.

Transform Script: As the name suggests, transform scripts are used to transform the data of an import/staging table to data which the target table expects. E.g. Staging table contains an email id field, this field is used in the transform script to fetch the user id of an existing user.
