pyLastSignon column is empty in pr_operator table



When a user logs in to the Pega application as an operator using Single Sign On (SSO), the pyLastSignon does not update in the pr_operators table.

Error Messages

Not Applicable

Steps to Reproduce

  1. Log in to the Pega application with any valid user ID.
  2. Verify pyLastSignon.

Root Cause

An issue in the custom application code or rules.

The authentication scheme used PRCustom to save the operator ID, by default, in the pr_operators table with the pyLastSignon property. In the authentication activity, the user saved the operator record, which was later saved with a blank value for the pyLastSignon.


Remove the Obj-Save to resolve the problem.
