property, enter an integer value greater than 1 and less than the value set for the Data Integration Service.

Or you can assign a user-defined parameter to the property, and then define the parameter value in a parameter set or a parameter file.

To define a suggested parallelism value for a specific transformation in the mapping, enter an integer value greater than 1 for the transformation in the

Suggested Parallelism

section.

The following image shows a mapping with an overridden maximum parallelism value and with the default suggested parallelism values for transformations:

Save the mapping.
