How do you enable the insertion of the GenProcID in PersonWantsOrg?

I want to use the GenProcID@PersonWantsOrg to trace back the rootcause of an entitlement removal.

For example:

' Key of the column GenProcID@PersonWantsOrg
Const genProcIdAtPersonWantsOrg = "QER-FFC0277919D34FD8AABF1777FA8237A7"
...
$"exists (select top 1 uid_dialogwatchproperty from DialogWatchProperty A where A.UID_DialogWatchOperation = P.UID_DialogWatchOperation and UID_DialogColumn = '{ _
genProcIdAtPersonWantsOrg}' and ContentShort = '{genProcId}')"
...

In my environment (9.2) the GenProcID@PersonWantsOrg column is empty for all the PersonWantsOrg entries.
The "Common | ProcessState" config is enabled

My question: how do you enable the insertion of the GenProcID in PersonWantsOrg?

Thank you for your help,
Niels
