Show dynamic table in ALV grid

Hi !
how do I show a dynamic table in ALV GRID ?
I used the following commands:
call method cl_alv_table_create=>create_dynamic_table
exporting
it_fieldcatalog = it_fieldcat[]
importing
ep_table = gt_new_table.
assign gt_new_table->* to <l_table>.
create data gs_new_line like line of <l_table>.
assign gs_new_line->* to <l_line>.
I added records into the table
Now I got a dynamic table.
How do I show it in ALV GRID ?
thanks
Adi

here if you have any other fields to be added to the dynamic structure based on your requirement, you can add then and apped them to t_ifc. There is a special handling for unicode conversion- so for the numc and char fields the length is passed in a different mothed.

Modifying database table in ALV Grid

Hi all.
I need to be able to modify the database table in ALV Grid. Here's the code. The database table, that is displayed is 'zng_so_head', it's internal table is 'res_tab'. In the program i tried to create a button 'CHANGE' on the ALV-toolbar, but when executing the program there's no such button (why?). What code, screens, screen elements, etc. should be added to this program to provide a possibility of changing data of the database table 'zng_so_head' (i mean changing existing data, adding new lines and saving changes)?

Hi,
For the button on the toolbar,here is the code:
CLASS lcl_eh IMPLEMENTATION.
*METHOD:      HANDLE_TOOLBAR
*DESCRIPTION: This method provides the necessary detail required to
             create an extra button in the toolbar.
METHOD handle_toolbar.
    CLEAR ls_toolbar.
    MOVE 'CHANGE' TO ls_toolbar-function.
    MOVE 0 TO ls_toolbar-butn_type.
    MOVE CHANGETO ls_toolbar-text.
    MOVE 'ICON_DETAIL' TO ls_toolbar-icon.
    MOVE 'CHANGE' TO ls_toolbar-quickinfo.
    APPEND ls_toolbar TO e_object->mt_toolbar.
ENDMETHOD.                    "handle_toolbar
Also,if you are using the CHANGE button to record changes in the DB,then in the local class that you have defined,you should use the following method and then write the logic:
*METHOD:      HANDLE_USER_COMMAND
METHOD handle_user_command.
    CASE e_ucomm.
      WHEN 'CHANGE'.
CHECK_CHANGED_DATA
REFRESH_TABLE_DISPLAY
Now call the methods that i have given in my previous post.This function code will be checked at the event you click the button 'CHANGE'.I think you have done this in an ELSE condition in the PAI of the screen.Not too sure if it works in the PAI.

Show dynamic columns in ALV table

I have a question that i need to create report in ALV
like this ...
i need to select doc date e.g. from 03.11.2007 to 05.02.2008
and the report is expected to show like this
SO#   | cust | sales gp | 2007-11 order amt | 2007-12 order amt | 2008-01 order amt | 2008-02 order amt

something like that ....
the no. of period column which is depend on the range of selected doc date....
so how to do that ?!?!?

Dynamic Table in ALV

Hello experts,
is it possible to call an ALV via ( class cl_salv or fm REUSE_ALV_GRID_DISPLAY) with a dynamic table?
This dynamic table has for example one fix column for the material number and dynamic colums for additional data.
One material has 1 additional column, the other material has two additional columns.
So i need an ALV with 3 columns material add_data1 add_data2 (add_data2 of material one is empty this is ok).
To build an itab which can handle this is possible i know.

Hello Benjamin,
Maybe you already found a solution for this, but if not (or for others looking for a solution), here is a sample program that creates, fills, and displays a dynamic table:
report ztpar_dynamic_salv.
parameters: p_colnr type i default 3.
start-of-selection.
perform execute.
form execute.
data t_table type ref to data.
** create dynamic table
perform create_dynamic_table using p_colnr
                            changing t_table.
** fill dynamic table
perform fill_dynamic_table changing t_table.
** display dynamic table
perform display_table using t_table.
endform.
form create_dynamic_table using colnr type i
                       changing table type ref to data.
data: lo_field type ref to cl_abap_typedescr,
        lo_struct type ref to cl_abap_structdescr,
        lo_table type ref to cl_abap_tabledescr.
data: t_comp type cl_abap_structdescr=>component_table,
        l_comp like line of t_comp.
lo_field ?= cl_abap_typedescr=>describe_by_name( 'CHAR10' ).
do p_colnr times.
    move sy-index to l_comp-name.
    concatenate 'COLUMN' l_comp-name into l_comp-name.
    condense l_comp-name no-gaps.
    l_comp-type ?= lo_field.
    append l_comp to t_comp.
enddo.
lo_struct = cl_abap_structdescr=>create( p_components = t_comp p_strict = space ).
lo_table = cl_abap_tabledescr=>create( lo_struct ).
create data table type handle lo_table.
endform.
form fill_dynamic_table changing table type ref to data.
field-symbols: <fs_table> type standard table,
                 <fs_line> type any,
                 <fs_field> type any.
assign table->* to <fs_table>.
do 5 times.
    append initial line to <fs_table> assigning <fs_line>.
    do.
      assign component sy-index of structure <fs_line> to <fs_field>.
      if sy-subrc ne 0.
        exit.
      endif.
      <fs_field> = sy-index.
    enddo.
enddo.
endform.
form display_table using i_table type ref to data.
data lo_alv type ref to cl_salv_table.
field-symbols <fs_tab> type any table.
assign i_table->* to <fs_tab>.
try.
      cl_salv_table=>factory(
        importing
          r_salv_table = lo_alv
        changing
          t_table      = <fs_tab> ).
    catch cx_salv_msg.
      message 'Cannot display result!' type 'E'.
endtry.
lo_alv->display( ).
endform.

Making cell non editabale (of dynamic table) in alv

Hi,
I am working on a editable alv with a dynamic table <itab> .This table gets populated during runtime.Now I want to make few cell of this table not editabale (only few cell not the full columns) I knwo that the procedure is to
declare my outtab like
TYPES: BEGIN OF gs_outtab.
TYPES: celltab TYPE lvc_t_styl.        "field to switch editability
        INCLUDE TYPE /npu/edmt_aa_eac.
TYPES: END OF gs_outtab.
and in the celltab i pass the information of cells which will be non editable...But the problem is as my outtab is a dynamic table I cannot INCLUDE IT IN ANOTHER types.
Please help me how to do it???? Or is there any other way of doing it???

Hi Priya
Add the field of type lvc_t_styl while creating the field catalog.
Now
DATA lo_table TYPE REF TO data.
cl_alv_table_create=>create_dynamic_table(
    EXPORTING
      it_fieldcatalog = lt_fieldcat "the field catalog table
    IMPORTING
      ep_table = lo_table ). "the reference to the table gt_outtab with the style tab
FIELD-SYMBOLS <tab> TYPE ANY TABLE.
ASSIGN lo_table->* TO <tab> .
Now you can fill your <tab>.

How to print to tables in ALV grid

hi all
I have 2 internal tables with some values
i want to display the 2 internal tables in the grid one after another with some title
can anyone tell me how to do it
Thank you.

i think in grid you can not do like this (By using function module). But you can do it in OO approach for that just check the se38 with alvgrid* and search. you can findout lot of example there. And one more option is there by using alv block but it is a list display.
Just check this sample program of alv block

Two Internal Tables for ALV Grid

Hi Gurus,
I have a little problem here. I have a report to display cost of production. The rows is about 50 displaying amount in dollars (currency fields). I have this in ALV Grid. But my problem is that the last 4 lines of the report are not currency fields like the others, they are quantity fields.
How can i go about to display this last 4 lines in this ALV Grid. They are from different internal tables off course because of the data type.
In short. I just want to display these 2 internal tables in an ALV Grid.
Thanks in Advance.

Nested table in ALV grid

Hi all
i have the following types:
<begin of type1,
fieldA type i ,
fieldB type i,
<end of type1,
<begin of type2,
fieldC type i
fieldA type i,
<end of type2,
<begin of type3,
fieldA type i,
fieldB type i,
fieldC type i,
<end of type3,
<begin of type4,
fieldA type i
fields1 type type1 occurs 4,
fields2 type type2 occurs 5,
fields3 type type3 occurs 7,
fieldD type i,
<end of type4.
I would like to set a internal table of type4 in an ALV grid. How do you do this? because i thought it could
like to hear from you! And off course << Moderator message - Please do not offer points >>
kind regards
Anton
Edited by: Rob Burbank on Nov 9, 2010 2:03 PM

I have found another solution. I make one internal table with all the fields in it. It is not what i like, but it works...
thanks all for your replies!

Updating database table using ALV Grid class CL_ALV_CHANGED_DATA_PROTOCOL

Hi,
I am trying to use class CL_ALV_CHANGED_DATA_PROTOCOL to update a database table from an ALV grid.
I have used program BCALV_EDIT_04 as an example.
I am able to successfully processed inserted or deleted lines using the attributes
MT_DELETED_ROWS
MT_INSERTED_ROWS
but I also want to process modified lines.
I was just wondering whether anyone out there has some example code for this.
I can see that there are the following attributes available
MT_MOD_CELLS
MP_MOD_ROWS.
I would ideally like to use MP_MOD_ROWS rather than MT_MOD_CELLS but it is not clear to me what type MP_MOD_ROWS is.
If anyone has any example code for this sort of thing, please let me know.
Thanks,
Ruby

hi Ruby,
Yes we can use that *data reference variable *.
It is a variable( something comparable to a pointer ) that points to a int table( table with changed contents )
which ll be created at run-time based on the data type ot the internal table that we pass to the parameter it_outtab of method set_table_for_first_display ...

Modifying database table through ALV-Grid

Hi all.
I need to modify a database table (ZNG_SO_HEAD) by entering data in ALV-Grid, which displays its internal table (exact copy of ZNG_SO_HEAD), and clicking the button ('CHANGE') on the ALV-toolbar. The ALV is already editable, the button already exists. Here is the code. After changing data in ALV and clicking 'CHANGE' on the toolbar the database table ZNG_SO_HEAD remains unchangeable, but i need to change data in it somehow.
Thanks all.

How to show check box in ALV grid??

Hi All,
     I am using an option edit in the feild catalogue which allows me to change the values in a few columns in the ALV list.
What I want is to be able to show a check box in a few columns which user can check and use the value X in the program for the later processing....
Can somebody tell me how to show a check box in the ALV screen in the changeable format??
Win full point by answering this typical question..
Thanks - Chandan
