How to change Cardinality of Process Context Data from 1:1 to 0:1?

[mubeenmalik]

I built a BPM process using the Name / Age tutorial @ http://www.google.com.pk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CBsQFjAA&url=h...

I want to make name as an optional process context data.

Anyone knows if this is possible and how to do that?

I am using SAP Netweaver 7.3 for the BPM along with NWDS 7.3 with SP01.

regards,

Mubeen
