Hi Venkat or anyone else,

Using the FM ALV grid, what event do you use to have the internal table (in your sample, i_data) updated with the new checkbox value after it has been updated from the ALV grid?

I tried using event MODIFY_LIST, but I could need get it to be executed.

Thanks!

I found out how the internal table updated with the new value of the edited field.

When calling function module REUSE_ALV_GRID_DISPLAY, you need to pass into I_GRID_SETTINGS with field EDT_CLL_CB set to 'X'.

The table is automatically updated with the new value.

Hi,

Add this piece of code in FIELD CATALOG form. U will get it.

CLEAR line_fieldcat.

line_fieldcat-fieldname = 'CHK'.

line_fieldcat-tabname = 'I_DATA'.

line_fieldcat-seltext_l = 'Checkbox'.

line_fieldcat-checkbox = 'X'.

line_fieldcat-edit = 'X'.

APPEND line_fieldcat TO i_fieldcat.

If you want the entire program let me know. Will give you.

Hello

Do you have always your problem to add editable chechbox in normal alv? I have the same problem... Maybe you have already a solution? Sorry for my bad english...

Greetings from Switzerland.

Hi kiran,

You have to fill the loyout structure to have check box in alv.

Interaction

box_fieldname type slis_fieldname, " fieldname for checkbox

box_tabname type slis_tabname," tabname for checkbox

box_rollname like dd03p-rollname," rollname for checkbox

for interaction in checkbox see the example program

BALVST02_GRID

Kiran,

I don't why you are using the function modules for the editable ALV's. My suggestion go for Grid control and it will be very easy.

All you have to do is in the field catalog make that field editable by putting in the value 'X' in the field EDIT. Also check the field CHECKBOX so that it is displayed as a checkbox. This will be of the type LVC_T_FCAT.

If you are bent upon using the function module in the table IT_FIELDCATALOG also there is a field called CHECKBOX. So, just fill it and should display the checkbox.

However, I don't think you can have an editable ALV with function modules. Correct me if I am wrong.

You don't need to fill the layout struture

Kiran,

For one single report you cannot use a function module as well as class.

Yes, the grid control and the class that I mentioned are one and the same.

Look at this weblog of mine.

or

Here is the easy ref. guide to the grid control.

Ravi,

Thanks for what you have given.But the problem is that we already used REUSE_ALV_GRID_DISPLAY so can i make any changes using this one.
