Impact Analysis

I have an scenario that whenever Role modification is happening , I have to do the Impact analysis using OOTB call method "action=“launchImpactAnalysis” ". I am using this call method in parent workflow “Role Management WF” to reduce the creation multiple workitem.

Here i get the Impact analysis hyperlink in workitem, but Total Gains and losses are not reflecting.

I am not sure if i missed something. Attached the sample .

Could anyone have any idea or help me out.
