Notification is not getting when PD is created

Summary

Employee does not getting the notification when PD is created

Content

Performance document is created/assigned through eligibility batch process with ticking 'Yes' on Create Eligible Performance Document. But none of the employees got the notification that they have been assigned a performance document. I have checked all the performance management notifications also and previously got the notification when I created the batch process. Is there any behaviour on this.
