Specifying an Identification Key
The identification key can be used as a user-defined ID for the task. For example, if the task is meant for approving a purchase order, the purchase order ID can be set as the identification key of the task. Tasks can be searched from Oracle BPM Worklist using the identification key. This attribute has no default value.
In the Identification Key field of the Advanced tab, enter an optional identification key value to specify a key.
