how to add push button in alv list
I am doing ALV report, in that i have some requirements as mentioned below
6. In the main report screen, each row should have a selection button at the left end. The entire row should be selectable by clicking on this button. By clicking on the button a second time the row gets deselected. The user should be able to select only one row at a time (i.e. he should not be able to select multiple rows simultaneously).
7. All Report screens should have standard SAP Navigation buttons.
8. The main Report Screen should have a Refresh Button. When the user clicks on this Refresh button the program should remember and re-execute (i.e. refresh) the last selection of the user in the Selection Screen above and the Main Report Screen should be re-displayed accordingly.
