25.1.9.1.7.6 Assigning Task Parameters to Variables

Store completed task parameter values in workflow variables for later activities.

The workflow pauses after creating the human task instance. When the task's lifecycle completes, it proceeds to the next activity. If later workflow activities need to reference the values of the updatable task parameters acquired during the human task lifecycle, they can use the GET_TASK_PARAMETER_VALUE function in the APEX_HUMAN_TASK package.

Its first parameter expects the unique id of a task, motivating why it's useful for a Human Task - Create activity to return its task ID into a workflow variable. Recall that in this workflow, the return variable for the task ID is V_TWO_NUMBERS_TASK_ID.

If you find it more convenient to store a task parameter value in a workflow variable, then as shown below, a subsequent Execute Code activity can call this same API to assign the updatable task parameter values into workflow variables using code like:

:V_VALUE1 := apex_human_task.get_task_parameter_value(
               :V_TWO_NUMBERS_TASK_ID,'P_VALUE1');
:V_VALUE2 := apex_human_task.get_task_parameter_value(
               :V_TWO_NUMBERS_TASK_ID,'P_VALUE2');
