ALV Grid: method double_click provides wrong information with 'totals line'
Hi together,
I´m using 'method double_click' with an ALV grid...like:
CLASS lcl_events IMPLEMENTATION.
METHOD double_click.
READ TABLE it_outtab INDEX e_row-index INTO s_datatab.
Everything works perfect as long as I don´t use totals with it.
Using totals /subtotals lines 'READ TABLE...' provides a wrong row-index.
Any idea how to resolve this problem?
Thanks for any helpHi, this is a big problem when you use OO to build an ALV, to resolve your problem, you have to implement an event TOOLBAR_BUTTON_CLICK to get button function, when your code pass by this method you have to use the method
CALL METHOD gcl_grid->set_function_code
CHANGING
c_ucomm = l_ucomm.
l_ucomm is the function code of button, the method set_function_code sort your internal table dynamically and you get the correct index when you use double_click.

Alv grid / method cl_alv_changed_data_protocol-add_protocol_entry
I used the demo program BCALV_GRID_EDIT to implement my editable grid and now I got stuck in the
method data_changed, where I do that loop:
LOOP AT rr_data_changed->mt_good_cells INTO ls_mod_cells.
where I check, get the values and modify the cells.
If something is wrong, I call the alv error protocol like this:
CALL METHOD rr_data_changed->add_protocol_entry
EXPORTING
i_msgid = '0K'
i_msgno = '000'
i_msgty = 'E'
i_msgv1 = text-004 "Buchungskreis
i_msgv2 = l_rbukrs
i_msgv3 = text-006 "exisitiert nicht
i_fieldname = ls_mod_cells-fieldname
i_row_id = ls_mod_cells-row_id.
The right wrong value is highlighted in red, the message is displayed, everything works fine until I change the value back to normal.
Then I get a run time error TSV_TNEW_PAGE_ALLOC_FAILED because MT_GOOD_CELLS couldn't be expanded.
It happened in class CL_ALV_CHANGED_DATA_PROTOCOL, in method MODIFY_STYLE in line 41.
append ls_modi to mt_good_cells.
I already tried to debug that method, to see what went wrong, but the debugger doesn't work any more at this point.
I guess I use the method wrong.
Does it has got something to do with
cl_gui_control=>www_active which is not active in my test? (p_loce in BCALV_GRID_EDIT)
I tried already many things with refresh_protocol and protocol_is_visible but the problem does not change.
Any suggestions? Should I simply choose to a message_list class and do the highlighting manually?My problem is solved, because the method modify_style was the reason for the run time error.
I called for one special field in the loop at mt_good_cells the method modify style
which tried to append a line to it.
append ls_modi to mt_good_cells.
in a loop to change the internal table the loop is based on isn't a good idea.
So the memory ran out and the system hang up when the memory size for the table was overrun.
Thanks for listening, the problem is solved. -

Display listbox key value in ALV GRID method
Hi All,
I have a program in which columns are generted dynamically based on number of fields. The column name is dynamic as it depends on its text while The value in Column's can be 1, 2, 3, 4, 5.
I am trying to display this in a list box along with the text which are maintained as fixed values at domain level.
space Walking
1 Archery
2 Boxing
3 Cycling
4 Rowing
Also I am displaying by using 'DD_DOMVALUEs_GET, looping through all the fixed values and concatenate
domvalue_l ddtext separated by cl_abap_char_utilities=>horizontal_tab. No tab space is coming between key and value.
Also for the 1st value which is space it is not coming properly as space is condensed.
The point is that after I am putting values in the grid. The system event data changed is called where the value selected is 1 Archery and it is going to bad cells, error protocol display . I want only the 1st character. How to modify the content in the grid before the system event gets called.

Control of ALV Grid displayed on 2 screens
Hi all,
I'm working on a program that does the following:
1. Select option screen is displayed for user to query DB table.
2. Query results are stored in an internal table and displayed on second program screen within an ALV grid. Some columns in this grid are editable.
3. User edits columns in grid and selects rows to process. When the user pesses a button the data is processed and a third screen is displayed containing the selected and processed rows...again within an ALV grid.
All works well with one exception...I use one container and one grid to display the data on both screens. If I navigate to the second screen and then try to return from the second screen to the select option screen by pressing the BACK button all is good in the world...I go back. If I am on the third screen and I try to return to the second screen, again all is good, I return to the second screen. The problem is when I try to go back one more screen. It seems it takes me 3 clicks to get back to the select option screen at this point. Any ideas folks?Hi Ankur,
Let me give some more detail.
1. Each screen has a custom container embedded within it. I have defined one container handle and one alv grid handle in my program. I use a call to the custom container method link to point my container handle to the correct screen.
2. I call alv grid method set_table_for_first_display only...no call to refresh_table_display...as I insert a different table and layout in the grid on each screen.
3. I call flush after each call to set_table_for_first_display
4. Following are my pai events:
MODULE user_command_9000 INPUT.
save_okcode = okcode.
CLEAR okcode.
CASE sy-dynnr.
WHEN 9000.
CASE save_okcode.
WHEN 'CONVERT'.
PERFORM convert_orders.
CALL SCREEN 9100.
LEAVE SCREEN.
WHEN 'BACK'.
SET SCREEN 0.
LEAVE SCREEN.

If I am on screen 9000 and click the bakckbutton I end up on screen 9100 again. If I click the back button 2 more times, now, I end up back at the selection screen. Thanks. -

RahulHi,
In IT_FIELDCAT you can pass one field with attributes of check box.
for example.
Declare:
DATA: GT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,
FIELDCAT_LN LIKE LINE OF GT_FIELDCAT.
Pass the below values.
FIELDCAT_LN-FIELDNAME = 'CHECK'.
FIELDCAT_LN-TABNAME = 'ITAB1'.
FIELDCAT_LN-KEY = ' '. "SUBTOTAL KEY
FIELDCAT_LN-NO_OUT = ' '.
FIELDCAT_LN-SELTEXT_L = 'Check Box'.
FIELDCAT_LN-CHECK-BOX = 'X'.

Check_changed_data method on editable ALV Grid ( class cl_gui_alv_grid)
Hi guys,
I use the following method (register_edit_event) in the PBO soon after first display of an editable ALV grid to register enter as an event to do validations on fields like qty. If user enters some character like 'abc' for qty and hits enter on keyboard, ALV grid pop's up a standard message ( I haven't coded for this.Since I use DDIC structure in field catalog, the Std. ALV program takes care of it. ). THis takes care of the validation before I click on save.
call method alv_grid->register_edit_event
exporting
i_event_id = cl_gui_alv_grid=>mc_evt_enter.
This works fine. But I want this validation to run when I also click the SAVE button of the screen. Is it possible to run this standard validation in my PAI event eg. SAVE ? I thought I will be, by calling the method check_changed_data in my PAI event. But this is doing nothing. Does this method conflict with register_edit_event or something ? So , basically what I am looking for is to trigger the event or call the method which does the same work as the "check" button on ALV grid.
Any advice or tips or sample code is greatly appreciated.
Thanks,
ShareenHi Shareen,
Handle the data_changed event in the grid.
Whenever you make changes in the data in ALV Grid this event would be triggered. Here you can perform additional validations that you may need to perform.
METHODS handle_data_changed

IMPORTING er_data_changed.
Implementation:
METHOD handle_data_changed.
PERFORM validations USING er_data_changed.
ENDMETHOD.
FORM validations USING er_data_changed TYPE REF TO cl_alv_changed_data_protocol.
DATA: ls_good TYPE lvc_s_modi.

CALL METHOD g_grid->register_edit_event
EXPORTING
i_event_id = cl_gui_alv_grid=>mc_evt_modified.
LOOP AT er_data_changed->mt_good_cells INTO ls_good.
CASE ls_good-fieldname.
WHEN 'FIELDNAME'. "Your fieldname
CALL METHOD er_data_changed->get_cell_value "Get the changed value
EXPORTING
i_row_id = ls_good-row_id
i_fieldname = ls_good-fieldname
IMPORTING

How to make a field manadatory within ALV Grid using methods and classes
Hi,
I am using ALV Grid using set_table_for_first_display
inside my dialog programming. I have a field called project number inside my grid which has to be made as mandatory field.
I have defined a method called catch_data_changed inside my class lcl_event_receiver. This method captures the changes made to one of the fields inside my ALV grid and displays all the default values of the other fields from the grid.
Now, i have to make project number which is one of my fields inside my ALV grid as mandatory. At the field catalog level i did not find any such option for making a field as required field.
Is there any other way, i can accomplish this within the ALV grid?from my understanding from ur question, i understood that u want the editable field inside alvgrid to be mandatory.
i dont know anthing in fieldcat, but u can try the following logic.
FORM DATA_CHANGED USING P_ER_DATA_CHANGED TYPE REF TO
CL_ALV_CHANGED_DATA_PROTOCOL .
DATA: L_VALUE TYPE LVC_VALUE,
ls_mod_cell type lvc_s_modi.

Possible to have vertical scroll bar for a cell in ALV Grid (using methods)
Hi All,
I have a field with length 100 characters on a ALV Grid (using methods)..User doesn't want to scroll all the 100 characters horizontally to see the whole text rather he wants to have a vertical scroll bar for the cell so that he can scroll vertically.
Is it possible to have split the cell text into lines and have a vertical scroll bar for a cell in ALV Grid?
Regards
Jaker.Thanks for the suggestion Balu.I tried this , but while scrolling,headers also getting scrolled.
Becoz of this , if i scroll down to the last row,headers are getting hidden.
Headers should always be static.only the data should scroll.
Since h:datatable is being rendered as one table , i can div tag for this table alone.
If i have seperate datatable for headers alone i can do this .But i should not use two datatables. -
Can we call ALV grid in a method?
hello everybody,
Is it possible to display the output in ALV from a <b>class-method(Global class)</b>?
in a class-method wee cannot call a screen, so is there any other possibility to display the grid??
thanx in advance,
abhilash.Don't USE ALV Function modules wherever possible. Go OO --it's simple once you get the hang of it.
Of course you can do it.
Here's a general class including an event handler in the SAME class. This can be used for DYNAMIC tables, DYNAMIC FCATS and custom events. The method DISPLAY_GRID here will do what you want.
Your structure list and fcat data are in the field-symbols <fs1> and <fs2>
Here's the code. This program just reads 200 lines from KNA1 and displays some data in a GRID with a toolbar. Press the EXIT arror to quit the program.
You need to define a blank screen (SE51) with a custom control on it called CCONTAINER1.
The screen logic as follows
PBO.
MODULE status_0100 OUTPUT.
You don't need a PAI as we are using the toolbar with events.
OK here goes.

If you look in the method display_grid you'll see that the method can call ALV classes and functions.
Isn't the above much easier than messing around with obsolete function modules --and you can write virtually the same code for ANY table. You can also in the events add eitable functions etc.
In fact we could even make it simpler.
I'll try and post the code later but in fact we could get the CLASS to do almost the entire thing so the only statements you would actually need in your ABAP would be
Your Data
Instantiate the class.
Call the class with a new method to do all the coding up to generating the ITAB.
