@kerrie45 this community isn't where you do your mileage claim. You need a different profile to access www.concursolutions.com. That is the site where you can do your mileage claim. I looked up HCL and didn't see a profile for you there.
I recommend speaking with your direct manager to see if you have a concursolutions profile or not. Not until you get that figured out and set up, you won't be able to submit a mileage claim.
