REUSE_ALV_GRID_DISPLAY - get edited data

Question

Hi,
I am using REUSE_ALV_GRID_DISPLAY where some fields I set to input/edit. The whole GRID is not set to edit mode. Additionaly I add a button in the toolbar so the control comes via user command event. My question now is how can I get the actual content of my edited fields if the user pushes the new button?
Thanks Achim

Answer 1

Hi,
I am giving you a sample code of ALV  with editable fields at the output.At the output when user selects some records and pushes a button on the application toolbar it takes the edited records and calls smartform and pass the records to the smart form.
