The Parameters tab only contains data for tasks that are associated with an Integration Type and have parameters. Integration Types provide links to external applications. On the Parameters tab, you can set specific information about the task and how it is run. The parameters are passed to the external application. For example, if the task contains a link to a data grid, you might use the Parameters tab to select a point of view for the grid.
If the parameters are not defined when the task is ready to start, an email is sent to the task owner. The task waits to start until the values are provided.
