I have a requirement to do some validations whenever the user enters the license plate number in
ESS Travel and Expenses / Create Expense report / Mileage Details .The system must throw a message if the user enters a wrong license plate number.
How do i know whether this is ABAP WD iview or JWD iview.IS there any BADI or BAPI for the validations.
Where is the information about License plate getting saved.
I have created a custom infotype for my requirement. The license plate must be validated from the data present in this infotype.
Can someone post me some advice on this please.
