It took me ages to find too ... but you need to create an account on the SAP Customer Influence page influence.sap.com (after I already created an account to join the 'community' you would think these things would all be linked) anyway once you create the account you can search for the request ID in the top right of the screen.
If it helps in the interim, I've found a way to temporarily help with this (if your set up is the same as mine) When you have all your available expenses listed mine have mostly started coming in with no city attached at all, then you selected them all and move them into a 'claim' - if you just move one expense - go in and update that to your correct city, when you go back to the main page and selected everything else that you want to include in that claim and move them over, everything that was blank will automatically update to whatever is already in the claim. It doesn't capture everything, and it only works when the original city of purchase is empty, but its saved me a lot of time.
Fingers crossed we get a real fix to this issue soon.
