I am using activiti bpm engine to control my workflow. Is it posible to step back if I made mistake in chioce? if no, what should be done? Must I complete the workflow and start a new one?

There is no such thing as 'going back' in workflow, it's well against.. the flow ;) If you wan't to give user the possibility to 'step back' you can model additional flows again to the same task which has been just completed.
