Field help (EXTWSTPJM2)

Use this field to identify the default resource (work center) to be used for this operation when a new task for this task category is added to a project.

You can assign two default resources to the same operation. For example, both a labor resource and a machine resource might be required to complete this operation. The valuation for the operation will be the total cost of the first resource plus the cost of the second resource.
