How to trace be

Hello,

I have several users who are reporting that they are not receiving all of their journal workflow approval emails.  So this problem is not across the board for all the journal approvers and these specific are getting some of the emails.

I queried on record EOAWEMC_PND_HDR.  I can see the USERID and when an email was sent and the email address it was sent to.  Problem is...I would like to be able track a specific journal id to see if it was sent.  I notice that there is a field called GUID which appears to be a unique identifier for the approval transaction.  Is there any way to use this GUID field to trace back to the journal id?  If not the GUID field, is there any way to find out if a specific journal id was sent via email?
