Hello Sita,
My earlier reply to you was that I am able to see all the covered individuals and their dependents with SSN except the XML tag I indicated.
I went through the note and saw that to have that tag generated in the XML you need to rerun the HRBENUS_ACA_PERSON transaction which we didn't choose to due to the risk of counts of 1094C being disturbed.
Hope this helps.
Thanks
Ashwini
