Retrieve Data from ALV without using GET_SELECTED_ROWS

[achraf_smaali]

Hi ABAPers!!

First of all let me tell you that I'm working in ACCENTURE Casablanca(Morocco) and this is my first Job in my career.

I'm working on an ALV OO, the program concists on creating an ALV using OO, In my selection screen there's a parameter of type DBFIELD I provide the name of table and it returns the table's fields in another dynpro (screen0100), To do this I used the FM: 'DB_GET_TABLE_FIELDS' then I append the internal table returned in another one to add the field CB (CheckBox), and I add a button in the toolbar, the function of this button is to generate a MySQL script To create the table provided by the user in my parameter (Screen 1000), but the fields of this table in the generated script are only the selected ones by cheking the checkbox in the ALV.

At first I used the method GET_SELECTED_ROWS and the sel_mode = 'C' in the layout structure but it doesn't returns any thing in the lvc_t_rowid table, moreover my boss refused that I used this method and he adviced me to use the event button_click.

So could any one help me with some piece of code?!!

Thanks kiran kumar Reddy for your time,

The fieldcatalog u adviced me to add is the first step I did when I start building my program, But when I want to press the button after checking the checkbox field, my program dumped which due to the incompatibility between the table returned by the FM 'DB_GET_TABLE_FIELDS' and the fieldcatalog because of the added field 'Check'. that's why I've created another internal table which includes the structure DBFIELD and another field called 'CB' to be handled as a chekbox and this is the it which I provide as it_outtab to my CL_GUI_ALVGRID.

But as you told there is another way which I'll try is to loop at the internal table and I'll check if the CB field = 'X' then I append this line to another it which I'll base on to generate my script

[achraf_smaali]

Thank you very much kiran kumar Reddy!!

I try it and it works fine with me, one little thing pllllz, the Internal table which I filled to generate my script it is appended after I push the button in the toolbar but I want to fill it while I'm checking my chekboxes plz tell me which event should I use? I don't really know what to do?!! ^__

Hi.,

I dont think it is possible..!! if it is Web Dynpro., there are events like onSelect., but here., on double click we can do., but we are jus selecting check box., try to put hotspot for that column..

n my suggestion is once selecting all records and pressing button is gud option., bcoz when u use hotspot also u need to check whether it is checked or not instead of blindly appending..

hope this helps u.,

Thanks & regards
