ALV report in OO concept

hi all
I am working on ALV report in OO concept. and facing in some difficulties in sorting, subtotal, coloring etc.. so it would be great help if there some sample program which can handle all this..
***Create new instance ALV table object
    TRY.
        CALL METHOD cl_salv_table=>factory
          IMPORTING
            r_salv_table = o_alv
          CHANGING
            t_table      = i_mara.
      CATCH cx_salv_msg INTO lc_msg .
    ENDTRY.
***.Enable Generic ALV functions
    lo_functions = o_alv->get_functions( ).
    lo_functions->set_all( ).
lo_functions->set_default( abap_true ).
***Sorting
    lo_sorts = o_alv->get_sorts( ).
lo_sorts->add_sort( columnname = 'BRGEW' subtotal = abap_true ).
    o_alv->display( ).
i tried this one but it is telling no column found and not doing subtotal..
pls giude
thanks

Creating ALV reports using OOP concept

After creating many reports i found out that 90% of the coding in a report is copy paste i.e. only 10% of coding effort is required which includes
 creating the custom data types and internal table variables ...
 populating the data
 creating screen,GUI status and GUI title
Just copy paste the below code and do as stated :
*ALV TEMPLATE
*create screen no. 2000
*change flow logic in screen if necessary
*create GUI status and GUI title
*change selection texts and text symbols*

Hello Jay,
Calling methods, creating instances, casting etc are not OOP. When you say you've developed an OO-report you think OO, refer to this blog to see what i mean - Global Data in ABAP OO Programs

hi
good
i tried your ALV report but it is giving some error due to some ztable you have used in your progam,
you can go to se38 and give there BCALV* and press f4, you ll find lots of ALV example related to OOP concept, you can test them and use them as per your requirement.

ALV report Object Oriented way without containers?

Hi guru
I was hearing that alv report using OO concept can be created only using containers... if we use containers can we run the job in background as its gui interfacing... is there a way to create using oo and with out containers. Thanks.

Hi Raj,
you can also use the new ALV object model class cl_salv_table for this. Refer to program SALV_DEMO_TABLE_REAL_SIMPLE to see how easy you can create a full screen ALV without container. Internally the class uses the FM REUSE_ALV_GRID_DISPLAY.

The ALV object Grid methods allow the same functionality as ALV grid report function modules but are displayed within
a screen (dialog program). SAP has provided a suit of programs which demonstrate how to For examples see standard SAP
programs as detailed below:
BCALV_EDIT_01 This report illustrates the simplest case of using an editable/noneditable ALV Grid Control.
BCALV_EDIT_02 This report illustrates how to set chosen cells of an ALV Grid Control editable.
BCALV_EDIT_03 In this example the user may change values of fields SEATSOCC (occupied seats) and/or PLANETYPE.
The report checks the input value(s) semantically and provides protocol messages in case of error
BCALV_EDIT_04 This report illustrates how to add and remove lines to a table using the ALV Grid Control and how to
implement the saving of the new data.
BCALV_EDIT_05 This example shows how to use checkboxes within an ALV Grid Control. You learn:
(1) how to define a column for editable checkboxes for an attribute of your list
(2) how to evaluate the checked checkboxes
(3) how to switch between editable and non-editable checkboxes
BCALV_EDIT_06 This example shows how to define a dropdown listbox for all cells of one column in an editable ALV
Grid Control.
BCALV_EDIT_07 This example shows how to define dropdown listboxes for particular cells of your output table.
BCALV_EDIT_08 This report implements an ALV Grid Control with an application specific F4 help. The following aspects
are dealt with:
(1) how to replace the standard f4 help
(2) how to pass the selected value to the ALV Grid Control
(3) how to build an f4 help, whose value range depend on a value of another cell.

Context menu's in Alv Report (Grid)

hello,
what i have done- i have created a ALV report by using the function modlue REUSE_ALV_GRID_DISPLAY.
what i want- When user clicks with Right mouse button on some cell.
context menu should get displayed. a list of menu should appear then user can select one of these options and eventually i'll on user command.
however i know the concept of context menu's and i have created context menu on screen elements in module pool.
but i have no idea whether these menu's can be created on ALV Grid.(simple ALv Grid----not ABAP OOPS)

check the program BCALV_GRID_06, it gives a demo of context menu functionalty,
but it uses cl_gui_alv_grid

'Save layout' button missing in the ALV report layout screen

Hi Friends,
 In one of our ALV report the 'save layout' button is missing in the report output screen.i have used the OO concept for creating the ALV output and not the function module.I have attached the code below used for creating the ALV grid.
CREATE OBJECT alv_grid
 EXPORTING i_parent = g_container_2.
CALL METHOD alv_grid->set_table_for_first_display
 exporting
 i_structure_name = 'PA0002'
 is_layout =
 CHANGING
 it_outtab = gt_outtab
 it_fieldcatalog = wa_fieldcat.
But i'm not able to trace why the 'save layout' button is missing in the output.Can anyone of you help me in sorting out this problem.
Thanks and Regards,
Vadivel.

Pass A to I_SAVE parameter. That will give the options to the user to save the layout outs.
I_SAVE = SPACE
Layouts cannot be saved.
I_SAVE = 'U'
Only user-defined layouts can be saved.
I_SAVE = 'X'
Only global layouts can be saved.
I_SAVE = 'A'
Both user-defined and global layouts can be saved.

Ravi

Logic For Subtracting A Given Output In ALV Report

Hi,
I am working on a report in which i am using ALV Concept and there a problem arise i.e. in ALV Report output which always subtotals having values in addition only and i want to know is there any way through which subtraction can also be performed within the output of a ALV Report.
Please provide some guidelines for it.

Rickky NV

Hi,
Thanks to both of you for your value able response. Actually, i am working on customer aging analysis report in which there are 2 columns i.e. debit and credit in which these both values are stored in 2 separate lines and i have to display the difference of them in the 3rd column and facing the problem.
Is it possible to display the required data of it in 3rd column of it?

What is the difference between list display and grid display in alv report

Hai genious
i am a new of the abap, i dont know the alv report, i have a small doubt, can u please tell me what is the main difference between list display and grid display in alv report
thanks&regards
chinnu

Hi ,
1. For all practical purposes, they are the same.
2. Some differences:
a) from abap coding point of view,
alv list is done with Function modules,
alv gris can also be done with FM,
but can also be done using OO concepts.
b) Alv grid (using oo concept) requires
designing the screen layout .
Hence, in one screen, we can show more
then one alv grid
(we cannot show more than
one alv list on one screen)
c) ALV grid uses ActiveX controls
present on the Presentation Server.
Hence, it consumes More Memory
on the presentation server.
d) ALV LIST is Display Only.
Whereas
ALV Grid Can Be made EDITABLE for entry purpose.
e) In alv grid, these options are possible,
but not in alv list.
without horizontal lines
without vertical lines
without cell merging during sorts
display total lines above the entries
I hope it helps.
Regards,
Mamta

Can somebody give some real time questions for alv report

hi guru
can somebody give some real time questions for alv report.
answers also.
regards
subhasis.

hi,
The ALV is a set of function modules and classes and their methods which are added to program code. Developers can use the functionality of the ALV in creating new reports, saving time which might otherwise have been spent on report enhancement
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).
Using ALV, we can have three types of reports:
 1. Simple Report
 2. Block Report
 3. Hierarchical Sequential Report

On ALV report in1 column I want to put Icon on every row of that column.

On ALV report there is 1 column I want to put Icon on every row of that column.That ALV program uses object oriented concept all class and methods.
I want to use that icon on that row. That icon name is ICON_OKAY
In my program when I assign values to internal table at that time I am assigning that ICON_OKAY value to that row as follow.
Itab-
Itab-icon = ICON_OKAY.
Append itab.

please follow below procedure to display icon in ALV
1) In corresponding fieldcatelog entry do
fieldcatalog-icon = 'X'
2) While filling the internal table fill the corresponding key value of icon , for example ICON_OKAY value is '@0V@' so statement would be
Itab-icon = '@0V@'
to get list of corresponding key for icon open include <ICON> in se38

here u need to 2 performs for PF status and USER_COMMAND in the ALV parameters.
create a custom PF status and create push buttons and assign your ok codes in your PF status.
if the field has to be edited in the ALV then pass EDIT = 'X' for that field in the fieldcatlog preparation.
Hope this will help you.
