Hi Mahendran N,
Have you seen this note's attachments?
There is an attachment on it that explains about the available fields. Some of them you can customize via transaction FITVFELD_WEB. Open the trip variable and the trip receipts. The fields from Fiori MTE that are configurable you can set as different representation and visibility flag as NONE.
I have not tested this yet on a real system, but I believe this will have the expected behavior.
If you cannot find the field on this spreadsheet, you might want to do some enhancements via Web IDE. Many things on this application cannot be customized via Extensions Pane. Thus you have to manually implement them. Main tasks are:
1) Create a Custom Controller for the view or fragment where you have the field to hide
2) Since there are lots of fragments on this app you will need to inject the code on the event "onAfterRendering". This is required because the usual place (onInit) will not carry out the changes once the fragment gets injected onto the View - thus any modifications on the Init method will not take any effect on the UI.
Enjoy,
Ivan
