Step 3. Define a Parameter Value

Step 3. Define a Parameter Value

Before you run a session, define values for mapping parameters in the parameter file. When you do not define a parameter in the parameter file, the Integration Service gets the parameter value from another place. The Integration Service looks for the value in the following order:
  1. Value in parameter file
  2. Value in pre-session variable assignment
  3. Initial value saved in the repository
  4. Datatype default value
