I need to display data in ALV grid using classes and objects and it has some input fields. And has one push button on screen if user enter anything in the input fields and press push button then those values have to be stored in Data base.
If user enter any data in the input fields and trying to come back with the help of F3 or back button with out saving the modified values then i need to show one pop-up with some message.
Now my doubt is how to capture the field changes in alv grid, and i want to know in which row user has changed the data, it means that row(s) only i need to modify in data base.
How to use data_changed method for capturing modified row(s) details.
