Changing Source Parameters in a File

Changing Source Parameters in a File

You can define multiple parameters for a session property in a parameter file and use one of the parameters in a session. You can change the parameter name in the session properties and run the session again with a different parameter value.
For example, you create a session parameter named $InputFile_Products in a parameter file. You set the parameter value to “products.txt.” In the same parameter file, you create another parameter called $InputFile_Items. You set the parameter value to “items.txt.”
When you set the source file name to $InputFile_Products in the session properties, the Integration Service reads products.txt. When you change the source file name to $InputFile_Items, the Integration Service reads items.txt.
