I displayed the output using alv grid display.
Here i want check box before the every row of the output.
Now after displaying the output i need to select some of the rows it means i need to check the check box for some rows.
Then those rows whose chechbox is checked are updated into a table.
Please tell me how to get the check box before every or the output and i need to check the check box after displaying the output i.e selecting some rows
thanks in advance
