Workflow - AX 2012 - Get Escalated To and Reassigned To User Name

Hi Everyone,

My requirement is to get Workflow Escalated To and Reassigned To User name from Workflow.

Description : 

Suppose i have one workflow X. When we see the tracking details we can see that it has been escalated from User A to User B.

I need to get the value of User B through X++ coding as i need it to display it on the report.

Kindly help anyone with the code snippets if any. 

Or from which table i can fetch the value of User B.

Same goes with the case of Reassigned To

Thanks in advance.
