Differentiate between mapping parameter and mapping variable?

Answer Posted / ysindhureddy77@gmail.com

A mapping parameter is a user definable constant that takes up a value before running a session. It can be used in SQ expressions, Expression transformation etc.


A mapping variable is also defined similar to the parameter except that the value of the variable is subjected to change. It picks up the value in the following order.

 From the Session parameter file
 As stored in the repository object in the previous run
 As defined in the initial values in the designer
 Data type Default values
