If I have set the property Treat Source Rows as Insert and for the target properties I have checked the boxes Update as Update, what will happen to incoming rows? What exactly is the use of these check boxes and in which scenarios we use them. Also what is the sequence in which informatica understands these properties.Does it takes whatever is defined in treat source rows as property or it is in any other way. Please explain.
