ALV OO and refreshing the ALV grid

Hi,
i have some problems with my ALV 00 program.
On screen 1 i have to fill in a material number.
For that material i'm getting some data and show in screen 2 in a ALV grid.
Via BACK-button i'm getting back to screen 1 and can fill in another material number.
But the 2nd (and 3rd, etc) time i fill a material, the ALV grid data from material 1 is shown. Even if the internal table I_ALV where the data is, is changed.
What should i do ?
I have initialized the customer container and the grid, but that didn't solved the problem.
regards,
Hans

Hi,
Try clearing and refreshing the alv grid data table in screen 2.
Check with this code. this code is working fine. If we go back and change the input, it is showing the output corresponding to the second input only.
Have you use this method?

How to refresh the ALV Tree

Hi,
I have an ALV Tree report developed using the OOPS. In my ALV Tree output, I have some buttons which will update the database after clicking. The data is correctly updating in the database. But, it is not getting updated in the ALV Tree display. That means, it is not REFRESHing the ALV Tree display. We have to again execute the program in order to see the updated output.
Could anyone please suggest me how to Refresh the ALV Tree display..?
We can't use the method 'REFRESH_TABLE_DISPLAY' as it is a PRIVATE method is the class CL_GUI_ALV_TREE.
Please share your valuable thoughts.
Thanks & Regards,
Paddu.

How to refresh the ALV Control

Hi Experts,
I have a selection screen and ALV control in webdydnpro report. If i enter valid input values in the selection screen the ALV contol is diplaying datas correctly but when i enter invalid data in the selection screen the ALV table control values still diplaying in the previous datas. I need to Refresh the ALV contol values once the incorrect data enter in the selection screen. How can i REFRESH the ALV control in Webdynpro report. I have Refreh button in the Selection screen when you press REFRESH button the ALV table control data should be initilize Kindly help me out this issue.
Thanks ,
Kumar

Hi.
You have a selection screen where user can enter some data, with this data you
perform a selection and then you bind the result to the ALV, right?
Question is how you bind the result to ALV? Do you use external context mapping
or the set_data method ?
So I guess you have a method where you validate the select options and if they
are correct you perform the selction and bind the result to the node for the ALV. If
the select options are incorrect you just need to get the node for the ALV (which contains the
previous result )and call the invalidate method on that node which deletes all
elements of this node and after that the ALV should be empty again.

If u want normal refresh based on clicking on a button then follow these steps:
1. Pass the subroutine name for event user_command to ALV list like:
CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
       EXPORTING
            i_callback_program      = sy-cprog
            i_callback_user_command = 'USER_COMMAND'
            is_layout               = ls_layout
            i_structure_name        = 'UINFO'
            it_sort                 = lt_sort
            it_event_exit           = lt_event_exit
       TABLES
            t_outtab                = gt_user.
2. In the routine USER_COMMAND trap the fcode and set the refesh field.
      FORM USER_COMMAND                                             **
FORM user_command USING i_ucomm     TYPE syucomm
                        is_selfield TYPE slis_selfield.     "#EC CALLED
CASE i_ucomm.
    WHEN 'ABCD'.
      is_selfield-refresh = 'X'.
ENDCASE.
ENDFORM.                               " USER_COMMAND
3. Attach custom pf-status and there define a button with fcode
ABCD.
So that whenever u press this button user_command routine will get called and ALV list get refreshed.

Unable to display Refreshed editable alv

hi
I have developed editable alv which contains 7 colums. the final column is the addition of 4th n 5th cplumn. when i refresh after changing the values, the final column is not changing. but while debugging the changed values are reflected in internal table but its reflected in alv.
help me out

in the user_comand form you have to put rs_selfield-refresh = 'X'.
like this:
*& Form user_comand
FORM user_command USING r_ucomm LIKE sy-ucomm
rs_selfield TYPE slis_selfield.
rs_selfield-refresh = 'X'.

Logic for Refreshing the ALV Report (Very Urgent)

Hi Experts,
My ALV report needs a refresh button on the output.
The Refresh button should be available to allow user to keep this report on screen and refresh regularly rather than going back and running it again.
I am using Function modules and not OOPS Concept here.............As i am unaware of OOPS Please provide me solution in FM's Only.
Kindly send me sample logic for this, Very urgent if ur reply is helpfull.... u will be rewarded heavily.......................
THanks in advance.
Rajesh Kumar

Hi,
This mean to say that if you have a 'refresh' push button in your gui status, every time you press the button, the list should get refreshed.
In ALV, to refresh the table you have to call the method "refresh_table_display".
It has the syntax very similar to creating the table.
It has two parameters. In the first one, you can mention if you want to refresh only the data (the icons are not refreshed)
or
if you want to refresh only the icons around the grid (the data is not refreshed - this option is mostly not used in day to day applications).
the synatx is :-
call method grid (name of grid )->refresh_table_display
exporting
IS_STABLE = <STRUCT OF TYPE LVC_S_STBL> (THIS IS FOR DATA REFRESHING)
I_SOFT_REFRESH = <VARIABLE OF CHAR 01> (THIS IS FOR ICON REFRESHING).

Bhaskar

Automatic refresh in alv grids

Hi!
I've three containers with three alv grids on my screen.
I've a self made save-button on the toolbar of the first grid.
Now i insert data in grid2 and grid3 ...
When i press now the save-button from grid1 there's no data in the internal tables from grid2 and grid3.
When i first press the refresh-buttons on the toolbars from grid2 and grid3 and then the save-button from grid1 the internal tables from grid2 and grid3 are filled.
Is it possible to simulate first the pressed refresh-buttons from grid2/grid3 when pressing the save-button from grid1?
I've tried to set a "call method grid2->refresh_table_display" and "call method grid2->refresh_table_display" before the code for the save-button but this doesn't work.
Is there any help for me?
Thanks a lot in advance!
Ingo

Hello Ingo
It is important to realise that pushing a toolbar button does NOT trigger PAI of the dynpro where the ALV list is displayed.
In order to refresh the display of the other two ALV grids you need to pass PAI (followed by PBO). How to do that? There are at least two possible ways:
(1) You handle the SAVE command in your method HANDLE_USER_COMMAND. Within this method you update the internal tables for grid2 and grid3 depending on the contents of grid1. At the end of this method you call method CL_GUI_CFW=>set_new_ok_code( 'REFRESH' ). This will trigger PAI of the dynpro. In the PAI module (e.g. USER_COMMAND_0100) you could write the following coding:
CASE gd_okcode.
 WHEN 'REFRESH'.
 go_grid2->refresh_table_display( ).
 go_grid3->refresh_table_display( ).
ENDCASE.
(2) You handle the SAVE command in your method HANDLE_USER_COMMAND and call method CL_GUI_CFW=>set_new_ok_code( 'REFRESH' ) without updating the itab2 and itab3 here. The updating of these itabs occurs in the PAI module.
The following sample report shows you the second approach. On the first ALV grid customers are displayed. If you double-click on a single customer its sales areas (if any) are displayed in the second ALV list.

Refresh Editable ALV Grid inside a custom Container

Hello all,
I am having a screen with custom container in which i am populating datas and a entry screen which is going to have my
filtering condition for this custom container screen..
The problem i am facing is whenever i come out of the custom container screen after displaying and again give the
necessary filtering data in the previous screen...
the custom container screen displays wrong values...
But when i refresh the data with the refresh icon in the container right datas are coming...
I even used CALL METHOD C_ALVGD->REFRESH_TABLE_DISPLAY
EXPORTING
IS_STABLE = STABLE
EXCEPTIONS
FINISHED = 1
OTHERS = 2. after displaying the values using
CALL METHOD C_ALVGD->SET_TABLE_FOR_FIRST_DISPLAY

I have refreshed my internal table once when i display and again fetched from the DB according to the filtering conditions given
in the first screen.
I have tried clearing the Object created once when i display and again recreated it.But could not get the output.
solution would be really helpful...

Hey all,
Thanks a lot for helping me...
The problem is solved....
i just used,
        CALL METHOD C_ALVGD->FREE. 'Grid inside the container
        CLEAR C_ALVGD.
        CALL METHOD C_CCONT->FREE. "Container
        CLEAR C_CCONT.
when i click BACK Button from screen 2 to screen1.

Refreshing of ALV Grid(using class)

Hi all,
In my program, i found that the ALV grid is displaying the same data for different criteria's. when debugging i found that the data is populated correctly in the output table that is passed to the method SET_TABLE_FOR_FIRST_DISPLAY according to the criteria's, yet i could only see the grid with the previous data.Please suggest on what could be done to correct this.
Thanks,
saran

Hi Saran,
There is a lifetime attribute that you have to set .
Set this when you create object container at the first time .
Here is the sample syntax :
Variable definition
DATA: grid_pr1 TYPE REF TO cl_gui_alv_grid,
      g_cconth TYPE REF TO cl_gui_custom_container,
      gs_layout2 TYPE lvc_s_layo,
      it_alv TYPE lvc_t_fcat .
DATA: it_pr1 type table of ZP119H. " custom structure
Create the object
IF g_cconth is INITIAL.
    CREATE OBJECT g_cconth
       EXPORTING
          container_name = 'CCONTH'
          lifetime = g_cconth->lifetime_dynpro.
    CREATE OBJECT grid_pr1
       EXPORTING
         i_parent = g_cconth .
    CALL METHOD grid_pr1->set_table_for_first_display
      EXPORTING
        is_layout            = gs_layout2
      CHANGING
        it_outtab            = it_pr1
        it_fieldcatalog      = it_alv.
ENDIF. " g_cconth

How to refresh an ALV (CL_SALV_TABLE) after a parallel process

Hello all,
I have created a list using CL_SALV_TABLE. When you click on a line, a new mode must be opened. There, the user will fill in some data that must be retrieved and shown in the main list when the user closes the new mode. To do so Iu2019ve used u201CCALL FUNCTION func STARTING NEW TASK task CALLING meth ON END OF TASKu201D statement.
Iu2019ve tried to refresh the list within meth (called on end of task) but it doesn't work. I've also tried to get all the data again, but it prompts a short dump, set a new ok code using method cl_gui_cfw=>set_new_ok_code, even a WAIT until process is finished (not valid because I need process 1 active all the timeu2026)
SAP help says u201CThe SET USER-COMMAND u2018OKCDu2019 statement replaces the REFRESH SCREEN commandu201D
CALL FUNCTION 'function'
 STARTING NEW TASK w_taskname
 PERFORMING end_of_creation ON END OF TASK

 i_manual_order = space

[Modify list]
 SET USER-COMMAND 'OKCD'.

AT USER-COMMAND.
CASE sy-ucomm.
 WHEN 'OKCD'.
 Perform get_data.
How can I have the same behaviour when using CL_SALV_TABLE??
Thanks in advance!

Hello Matt, 
does not work means that if I write the following within method ON END OF TASK, the report is not refreshed.
 
<pre>
o_alv->refresh( ).
</pre> 
I've also tried:
 
<pre>
o_alv->refresh( ).
o_alv->display( ).
data: o_alv TYPE REF TO cl_salv_table</pre> 
<pre>Short dump: RPERF_ILLEGAL_STATEMENT
Error analysis
There is probably an error in the program
 "SAPLSLVC_FULLSCREEN".
 The program was probably called in a conversion exit
 or in a field exit. These are implemented by
 function modules called CONVERSION_EXIT_xxxxx_INPUT/OUTPUT or
 USER_EXIT_xxxxx_INPUT.
 Conversion exits are triggered during screen field transports or
 WRITE statements, field exits during field transports from the
 screen to the ABAP/4 program.
 In this connection, the following ABAP/4 statements are not allowed:
- CALL SCREEN
- CALL DIALOG
- CALL TRANSACTION
- SUBMIT
- MESSAGE W... and MESSAGE I...
 - COMMIT WORK, ROLLBACK WORK
 - COMMUNICATION RECEIVE
 - STOP
- REJECT
- EXIT FROM STEP-LOOP
Moreover, conversion exits for output conversion
 (implemented by function modules called
 CONVERSION_EXIT_xxxxx_OUTPUT) do not allow
- MESSAGE E...
to be used.
Trigger Location of Runtime Error
 Program SAPLSLVC_FULLSCREEN
 Include LSLVC_FULLSCREENU01
 Row 187
 Module type (FUNCTION)
 Module Name REUSE_ALV_GRID_DISPLAY</pre> 
But this short dump is expected since CALL FUNCTION - STARTING NEW TASK help says u201CIn the callback routine, you are not allowed to execute statements that interrupt the program execution or terminate a SAP LUW. Statements for list output are not executed.u201D 
Thanks Matt, I'll take a look at that forum, but I also tried a self list refresh using a timer and that prompted another short dump: LIST_TOO_MANY_LPROS -> "Error analysis: At present, the maximum permitted number of nested screen levels is restricted to 50." 
If I find a solution I'll let you know. 
 
Thank you!!
