Unable to Access Process Context in my Process

Hi,

I'm trying to create a small process for one internal proof of concept using SAP PO 7.3 EHP1 SP0.

For my scenario i need to retrieve the current Process Instance Identifier.

I am aware that this information can be retrieved using the "ProcessInstanceAttributes" and should be available on 7.3 Ehp 1.

My problem is that i cannot see the attribute in the SAP NWDS interface.

I have created other processes before and the attribute was visible but somehow it just seems to have dissapeared from every process i have created.

Check the screenshot bellow of one of my processes.

Is there any type of configuration in SAP NWDS that can provoke this error?

How can i access/view Process Instance Attributtes again?

Im using SAP NWDS - 7.3 SP00 PAT0001

Thanks,

Best Regards
