It is only possible to pause a workflow instance when the workflow is Playing. The impact on the workflow’s currently-executing activity is as follows:
•Batch audience: the workflow enters a Paused state, as does the audience.
•Interactive activity: the workflow enters a Paused state, as does the activity. Any immediately-downstream activities also enter a paused state.
•Delay: the workflow enters a Paused state, as does the delay.
•Wait for Event: the workflow enters a Paused state, as does the wait for event. If the wait for event is associated with a scheduled trigger, the trigger does not fire at the trigger’s scheduled date and time if the workflow is Paused.
•Export: the workflow enters a Pausing state, and a Paused state having completed export execution. Upon playing, the export completes.
•Offer activity: the workflow enters a Pausing state, and a Paused state having completed offer execution. Upon playing, the offer activity completes.
•Decision offer activity: as per offer activity.
•Control: the workflow enters a Pausing state, and a Paused state having completed control execution. Upon playing, the control completes.
