Implementing button to terminate GP Process on Interactive Forms

Hi all,

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?

Best regards,

Ikue
