Enqueue SAP BPM - SAP PI 7.31 Single Stack

Hi experts,

     I would like to ask you if it is possible to enqueue SAP PI 7.31 BPMs (single stack)? And if yes how?

I have already work with PI 7.1 dual stack and I've got ccBPM which are enqued, but I have no idea how to do it in SAP BPM in 7.31 single stack.

Thanks.
