I'm implementing GP callable object of Interactive Forms.
I'd like to implement a button which terminates or cancels GP Process on my interactive form.
I've already set "%com.sap.caf.gp.if.PostProcessorUrl%" to the Submit button to complete this GP step and pass to the next.
But I could not find any information how to implement cancel button (I mean it will cancel GP Process) on interactive forms.
Would anyone give me some ideas?
