ALV Grid to select multiple records , edit , reprocess and then updated.

Hi,

I have an requiremnt

1) To display the records in ALV grid( NOT OO ABAP).

2) Need to select multiple records(need to avoid using control if possible while selecting multiple records)

3) Need to add 2 buttons 1) EDIT 2) REPROCESS

3) After selecting the multiple records, I need to select a column (only one) .

4) then the user will click the EDIT button : Once clicked a POP UP needs to appear with field name and blank space ,when data is entered into blank space

all the selected records will be updated.

5) THen on clcikng REPROCESS all the selected records needs to do certain reprocessing and updated/changed values needs to be updated in the GRID.

Let me know ..How to proceed ?

Is there any standard program which has the similar functionalty ?
