PR Workflow

Hello Experts ,

I have created the PR release Strategy and Workflow . My issue is when final release happens , the system is not sending mail to user to create the Purchase Order. For example -

The PR is released by X as first level and mail transmitted to Y. After Y release as final release , the mail has to trigger to Z to convert this PR in to PO.

But system is not functioning like this . User Y is getting mail after X release . However , Z is not getting mail after Y final release .

Do you have any Idea where need to be changed this ?

Thanks .
