ALV Grid: refresh in sub screens

Hello All,
I have some issues with internal table display in ALV grid.
The following is the scenario.
I am in a wizard which has 2 sub screens (SScreen 1 and sscreen 2).
1)On sscreen 1, i have a input field,where i provide a value and on clicking the next button i get a list of values which i display on sub screen 2 using ALV grid.
2)Now i go back to sscreen1 and change the value in the input field,since i use on-request module, i know the value in the field has changed and now i need to display new set of values on sscreen 2.
In this case i clear the internal table, get new values for internal table and then call set_values_for_first_display().However i still get the old values displayed on SScreen 2!!!!.
Any suggestions on what i might be doing wrong?
Cheers
Dev

Hi Vijay,
Thanks for the info.
I will try refresh_table_display option after getting to work in a couple of hours.
I am initializing the grid and control everytime i change a value on Subscreen 1 in the PBO of Subscreen 2(the screen where the ALV list is displayed).
That is the reason why i call set_table_first_display, whenever there are new values in the internal table and avoid refresh_table_display.
Cheers
Dev

ALV grid refresh problem - Icons briefly flashed on screen

Hi ,
I have an editable OO ALV grid which has a "New Entries" option. When the user clicks on that button a new blank row is appended at the bottom. The problem is on some monitors /screens when the user clicks on the button the ALV grid flashes for a brief moment and every cell has an image icon.
You can see this problem by going to Tcode SE16N choose a large table like VBAP and display 500 records or more. On the next screen press the page down button, you would see those icons.(the problem is as described above, except that the se16n ALV is not editable ).
Is this a buffering problem of ALV ? Or is there a way to avoid / fix this ?
Thanks

you will find a beginning of explanation here in [sap library - Using the ALV Grid Control in WANs|http://help.sap.com/saphelp_nw2004s/helpdata/en/32/d3e962f7fb11d2b48c006094192fe3/frameset.htm]

Hi,
Can any one tell me about the possibility to display sub headings for an ALV grid control i.e to have a group of columns under one column similar to the feature in excel?

ALV grid refresh problem when I return from list-processing

hi,
I have made alv grid with f4 help features and i'm using row select feature.
When i click on a button in Application toolbar, the program leaves to list processing and then return to alv gridscreen.
Now the problem arises.
(1)Even if i select rows and press F8, the program does not identify the rows selected and does not give me desired output.
(2)Also, when i press F4, the selected value does not appear in the text field.
Both the cases are working fine, if i dont press button and go to list processing.
Please help!!

You can use the function module as stated below -
FORM user_command USING r_ucomm TYPE sy-ucomm
rs_selfield TYPE slis_selfield.
CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
IMPORTING
ET_EXCLUDING =
E_FLG_NO_HTML =
E_CALLBACK_PROGRAM =
E_REPID =
e_grid = ref1
ES_LAYOUT_KKBLO =
ES_SEL_HIDE =
CALL METHOD ref1->check_changed_data.
This helps to get the data in the internal table refreshed as well as that on the screen so that both are in sync.
this is generally used on some event, you can also use it otherwise.

Reward if useful.

How to get the alv grid report in another screen when double click on basic

Hi.
I have created an alv report using class cl_gui_alv_grid.I got another report in the same screen,when double clicked on basic list(using double_click event).I want to get this report in another screen.What i have to do?(In classical reports i worked with sy-lsind = 1 ,but how to do here?)
How to set color to the selected rows in the alv grid report?I worked with change_data_from_inside method of cl_gui_alv_grid.But it didn't work out..
With Regards,
Ramana.

On double click event . you will have to call another screen say 9000.
now within screen 900 PBO.. you will have to prepare the fieldcatalog/layout.. and the table to be displayed there.
in PAI of screen 9000, you can return to the original ALV.
method double_click.
call screen 9000.
endmethod.
" now in PBO create a module display_alv2
module display_alv2.
'prepare the fieldcat/layout info for new alv
'add the data to the new ALV table
'instantiate the grid call.. etc
'call the ALV
endmodule
"in PAI
module exit.
case sy-ucomm.
when 'ENT1'.
leave to screen 0.
endcase.
endmodule
while preparing the field catalog you can mention the EMPHASIZE field, whish will give color to tht column
E.g
*--Service Order
    ls_fieldcat-tabname   = 'IT_FINAL_VALID'.
    ls_fieldcat-fieldname = 'AUFNR'.
    ls_fieldcat-scrtext_m = 'Service Order'.
    ls_fieldcat-ref_table = 'AUFK'.
    ls_fieldcat-ref_field = 'AUFNR'.
    ls_fieldcat-col_pos   = 1.
    ls_fieldcat-outputlen = 12.
    ls_fieldcat-emphasize = 'C400'. "This will add color to the cell
    APPEND ls_fieldcat TO fcat_valid.
Hope this helps.

Need to display two ALV GRIDs in a single screen

Hi,
I have a question, i'm using version 4.6. I want to display 2 ALVs in a single screen or by calling.
Step 1 : The internal table (which holds the data for the ALVs has to be populated before calling ALV1 or ALV2)
Step 2 : Display In a single report
ALV1 report (Editable ,Has to be a GRID)
ALV2 report (Non Editable, Has to be a GRID)
(or)
Step 1 : The internal table (which holds the data for the ALVs has to be populated before calling ALV1 or ALV2)
Step 2 :
ALV1 report (Editable ,Has to be a GRID, with a custom button to call ALV2 hiding the ALV1 ie not visible to user)
ALV2 report (Non Editable ,Has to be a GRID, with a custom button to call ALV1 hiding the ALV2 ie not visible to user)
Please help me <REMOVED BY MODERATOR>

The common features of report are column alignment, sorting, filtering, subtotals, totals etc. To implement these, a lot of coding and logic is to be put. To avoid that we can use a concept called ABAP List Viewer (ALV).
This helps us to implement all the features mentioned very effectively.
Using ALV, We can have three types of reports:
1. Simple Report
2. Block Report
3. Hierarchical Sequential Report
There are some function modules which will enable to produce the above reports without much effort.
All the definitions of internal tables, structures and constants are declared in a type-pool called SLIS.
1. SIMPLE REPORT.
The important function modules are
a. Reuse_alv_list_display
b. Reuse_alv_fieldcatalog_merge
c. Reuse_alv_events_get
d. Reuse_alv_commentary_write
e. Reuse_alv_grid_display
A. REUSE_ALV_LIST_DISPLAY : This is the function module which prints the data.
The important parameters are :
I. Export :
i. I_callback_program : report id
ii. I_callback_pf_status_set : routine where a user can set his own pf status or change the functionality of the existing pf status
iii. I_callback_user_command : routine where the function codes are handled
iv. I_structure name : name of the dictionary table
v. Is_layout : structure to set the layout of the report
vi. It_fieldcat : internal table with the list of all fields and their attributes which are to be printed (this table can be populated automatically by the function module REUSE_ALV_FIELDCATALOG_MERGE
vii. It_events : internal table with a list of all possible events of ALV and their corresponding form names.
II. Tables :
i. t_outtab : internal table with the data to be output
B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV. If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter(I_structure name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.
The Important Parameters are :
I. Export :
i. I_program_name : report id
ii. I_internal_tabname : the internal output table
iii. I_inclname : include or the report name where all the dynamic forms are handled.
II Changing
ct_fieldcat : an internal table with the type SLIS_T_FIELDCAT_ALV which is
declared in the type pool SLIS.
C. REUSE_ALV_EVENTS_GET : Returns table of possible events for a list type
Parameters :
I. Import :
Et_Events : The event table is returned with all possible CALLBACK events
for the specified list type (column 'NAME'). For events to be processed by Callback, their 'FORM' field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field 'FORM' filled and the entry modified using constants from the type pool SALV.
II. Export :
I_List_type :
0 = simple list REUSE_ALV_LIST_DISPLAY
1 = hierarchcal-sequential list REUSE_ALV_HIERSEQ_LIST_DISPLAY
2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
3 = hierarchical-sequential block list
REUSE_ALV_BLOCK_LIST_HS_APPEND
D. REUSE_ALV_COMMENTARY_WRITE : This is used in the Top-of-page event to print the headings and other comments for the list.
Parameters :
I. it_list_commentary : internal table with the headings of the type slis_t_listheader.
This internal table has three fields :
Typ : H header, S selection , A - action
Key : only when typ is S.
Info : the text to be printed
E. REUSE_ALV_GRID_DISPLAY : A new function in 4.6 version, to display the results in grid rather than as a preview.
Parameters : same as reuse_alv_list_display
This is an example for simple list.
2. BLOCK REPORT
This is used to have multiple lists continuously.
The important functions used in this report are:
A. REUSE_ALV_BLOCK_LIST_INIT
B. REUSE_ALV_BLOCK_LIST_APPEND
C. REUSE_ALV_BLOCK_LIST_HS_APPEND
D. REUSE_ALV_BLOCK_LIST_DISPLAY
A. REUSE_ALV_BLOCK_LIST_INIT
Parameters:
I. I_CALLBACK_PROGRAM
II. I_CALLBACK_PF_STATUS_SET
III. I_CALLBACK_USER_COMMAND
This function module is used to set the default gui status etc.
B. REUSE_ALV_BLOCK_LIST_APPEND
Parameters :
Export :
I. is_layout : layout settings for block
II. it_fieldcat : field catalog
III. i_tabname : internal table name with output data
IV. it_events : internal table with all possible events
Tables :
i. t_outtab : internal table with output data.
This function module adds the data to the block.
Repeat this function for all the different blocks to be displayed one after the other.
C. REUSE_ALV_BLOCK_LIST_HS_APPEND
This function module is used for hierarchical sequential blocks.
D. REUSE_ALV_BLOCK_LIST_DISPLAY
Parameters : All the parameters are optional.
This function module display the list with data appended by the above function.
Here the functions REUSE_ALV_FIELDCATALOG_MERGE, REUSE_ALV_EVENTS_GET, REUSE_ALV_COMMENTARY_WRITE can be used.
3. Hierarchical reports :
Hierarchical sequential list output.
The function module is
A. REUSE_ALV_HIERSEQ_LIST_DISPLAY
Parameters:
I. Export:
i. I_CALLBACK_PROGRAM
ii. I_CALLBACK_PF_STATUS_SET
iii. I_CALLBACK_USER_COMMAND
iv. IS_LAYOUT
v. IT_FIELDCAT
vi. IT_EVENTS
vii. i_tabname_header : Name of the internal table in the program containing the
output data of the highest hierarchy level.
viii. i_tabname_item : Name of the internal table in the program containing the
output data of the lowest hierarchy level.
ix. is_keyinfo : This structure contains the header and item table field
names which link the two tables (shared key).
II. Tables
i. t_outtab_header : Header table with data to be output
ii. t_outtab_item : Name of the internal table in the program containing the
output data of the lowest hierarchy level.
slis_t_fieldcat_alv : This internal table contains the field attributes. This internal table can be populated automatically by using REUSE_ALV_FIELDCATALOG_MERGE.
Important Attributes :
A. col_pos : position of the column

M. outputlen : output length
N. seltext_l : long key word
O. seltext_m : middle key word
P. seltext_s : short key word
Q. reptext_ddic : heading (ddic)
R. ddictxt(1) : (S)hort (M)iddle (L)ong

Two AlV Grids in a single screen

I want to bring two ALV GRIDS in a single report output screen.How can i achieve this through Classical coding( not OBJECT ORIENTED ). If possible please provide with codes.
thanks,
Venkat

Hello Venkat
I agree that using fm's this is an almost impossible task whereas using OO-based ALV lists it is just a piece of cake.
For a sample have a look at report ZUS_SDN_TWO_ALV_GRIDS in thread alv
or report ZUS_SDN_THREE_ALV_GRIDS in thread Alv

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.
        WHEN 'CANCEL'.
          SET SCREEN 0.
          LEAVE SCREEN.
        WHEN 'EXIT'.
          PERFORM free_objects.
          LEAVE PROGRAM.
      ENDCASE.
ENDCASE.
ENDMODULE.                 " USER_COMMAND_9000 INPUT
MODULE user_command_9100 INPUT.
save_okcode = okcode.
CLEAR okcode.
CASE sy-dynnr.
    WHEN 9100.
      CASE save_okcode.
        WHEN 'BACK'.
          SET SCREEN 9000.
          LEAVE SCREEN.
        WHEN 'CANCEL'.
          SET SCREEN 9000.
          LEAVE SCREEN.
        WHEN 'EXIT'.
          PERFORM free_objects.
          LEAVE PROGRAM.
      ENDCASE.
ENDCASE.
ENDMODULE.                 " USER_COMMAND_9100 INPUT
Again...the trouble is navigating from screen 9000 to 0 after I have already navigated from screen 9100 back to screen 9000 via the back button. 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.

Problems with ALV grid refresh

Hello,
I am writing a relatively simple wd application, I enter a few values in the select-options and display the data in an ALV grid. My problem seems to be that the grid values do not refresh if I change the selection conditions.
On going through the forum I saw a few posts which ask me to call the Node->Invalidate( ) method, but on using that my grid refreshes completely and data does not appear again, even on changing the input values.
I have pasted the ALV portion of the code from my onAction method - could you suggest what I could do to correct this? I realise this is a relatively stupid question, but I am very new to this technology and am trying to learn. Thanks in advance.
***Database selection (this works fine, tested in debug)
Bind the data to the context
 dyn_node = wd_context->get_child_node( name = 'TIME_ENTRY' ).
 dyn_node->bind_table( icatsdb ).
Connect to the component Usage of the ALV
 l_ref_cmp_usage = wd_this->wd_cpuse_display_alv( ).
 IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
 l_ref_cmp_usage->create_component( ).
 ENDIF.
Through the interface controller of the ALV Component set the DATA node dynamically
 l_ref_interfacecontroller = wd_this->wd_cpifc_display_alv( ).
 l_ref_interfacecontroller->set_data( r_node_data = dyn_node ).

Hi,
Did you change the statement SET PF-STATUS 'ZIMP' to SET PF-STATUS 'ZLIQ' ? If not, please do that, and run the program after activation.

ALV grid Refresh problem

hi,
I have 2 views, input and output these two included in a MAIN views.
when user key in their input values in INPUT view and the search results will be displayed in OUTPUT view using ALV grid.
the problem i'm facing here is, when user changes search criteria once after search results displayed.. it is not displaying with new search results. every time i have to give F5(Refresh) it is certainly not comfortable to deliver it as it is.
i have tried same scenario with simple query in our local server.. where it is working very well.
i really clueless what would be the cause.. is there any with SAP patch issues.
i have tried with refresh method of ALV component.
please help me out of this, i cannot use TABLE control every time to avoid this.
thanks,
gupta.

Hi Gupta,
Could you please let us know how you are filling the context node which is mapped to ALV table?
After the search criteria is changed, if you are doing it inside handler of the button or something like that, it should work.
Refer to the tutorial in the following link which shows an example similar to your scenario:
SAP List Viewer in Web Dynpro - Simple Example for Using ALV
please post the code also which you are using to fill the node in case if you still face the issue after referring to the above tutorial.
Hope this helps!
Regards.

ALV grid refresh while fcat and internal table change

Hi,
I am displaying an ALV output using OOPS ALV grid. It is displaying data from internal table t1.
Later I am changing fieldcat table content and I want to display with internal table t2. how can I do this.
It is not refreshing the fieldcat values in the ALV.
Which method I should call to refresh the ALV.
Thanks and regards,
Venkat.

hi,
to refresh the alv display.
you can use the method refresh_table_display
of the class cl_gui_alv_grid.

Multiple ALV Grid Panes in single screen

Hi all,
How can we get multiple ALV Grid panes in single output.
Is it possible to get the same without using OOPS.
Thanks in advance.

Hi,
You can do this by creating 2 custom controls on the layout of the screen, and then you will also need to create 2 custom containers in your ABAP program, 1 for each ALV.
Ex :
grid TYPE REF TO cl_gui_alv_grid,
custom_container TYPE REF TO cl_gui_custom_container,
grid TYPE REF TO cl_gui_alv_grid,
custom_container TYPE REF TO cl_gui_custom_container,

ALV Grid works in normal screen but not in modal

Hi,
I'm struggling with an alv control I've created. I need to have it displayed in a modal dialog window. It works fine in a "normal" window but when I change the screen to be modal nothing displays.
Anyone have any ideas or hit this issue before.
Screen is defined in a function group with a custom control.
Classes exist for model / view and ws.
A function module creates classes above and passes a container to the view class which creates an instance of CL_GUI_ALV_GRID. Function module then executes:
call screen 100 starting at 5 5. - ALV doesn't display
Call screen 100. - Works fine

Helps if you populate the custom control after you have called the screen not before !
