You can use a parameter file to specify parameter values in a mapping task.
Configure the mapping task and specify runtime values for each input or in-out
parameter.
On the
Runtime Options
page, download the parameter file
template.
The template contains mapping parameters that can be overridden at runtime and
their default values, if a default value was specified in the mapping. It might
not contain every parameter in the mapping.
Update the default values in the parameter file with the values that you want
to use at runtime.
Add any parameters not included in the generated template including partial
parameters and system variables.
Save the parameter file or copy the parameters to another parameter file.
On the
Runtime Options
page, specify the parameter file
name and location.
When you want to update a parameter value, update the value in the parameter
file instead of updating the value in the task.
