SORT IN ALV with Objects

Former Member — Wed, 12 Sep 2007 20:14:07 GMT

Hi , I want to build a sort table for my ALV output to show duplicate values only once. Currently I have three fields : material number , description and quantity , that are being repeated for all entries. How to use a sort and how to pass it to the field catalog .

you can write simple logic :

DELETE ADJACENT DUPLICATES FROM itab comparing matnr.

thanks

I forgot to tell you before deleting the duplicates

just use sort itab by matnr and delete it.

nothing with fieldcatlog,you just need add the code after select query.

Thanks

Right now my reprt is like this :

Matnr total quant kunnr quant

mat1 500 kun1 100

mat1 500 kun2 400

mat2 300 kun3 150

mat2 300 kun1 150

My output should look like.

Matnr total quant kunnr quant

mat1 500 kun1 100

kun2 400

mat2 300 kun3 150

kun1 150

I am using ALV grid in ABAp objects. There is only one internal table that is passed to the ALV.

Please see this revised post , this is more clear.

This is the display I am getting right now.

Matnr total quant kunnr quant

mat1 500 kun1 100

mat1 500 kun2 400

mat2 300 kun3 150

mat2 300 kun1 150

My output should look like.

Matnr~~- total quant- kunnr~~--- quant

mat1--

500
~~kun1~~--- 100

kun2 -

400

mat2--

300
~~kun3~~--

150

kun1----

150

if you want to display repeated data only once but not delete the records,

then the solution is to use the "sort table catalog" , a kind of input table for function REUSE_ALV* . Modify the "sort catalog" by adding those fields and sort order ,

then pass the "sort catalog" to the function along with other input ( e.g. field catalog ).

I am using ALV in abap Objects. If there is a sample code for achieving the output , I will really appreciate it.

thanks.

Check the below code ,bold one is important..

Just declare one more internal table and use control break statements ..,use total qty field as charcter for ALV Internal table

The problem that I am facing does not get solved by using these events. I have to actually use event handler to input a value , this should be subtracted from the total quantity for each block of code for matnr.

Thank you Seshu for your help. ,

Re: SORT IN ALV with Objects

Former Member — Wed, 12 Sep 2007 21:48:18 GMT

Which version of ALV objects are you using?

CL_GUI_ALV_GRID and related clases or CL_SALV_TABLE and related classes?

They're not the same; always please identify the actual class name since there is more than one way to do this in objects.

For CL_GUI_ALV_GRID, you have to set values in the field catalog and sort table:

DATA: gt_sort TYPE lvc_t_sort,
      gs_sort TYPE lvc_t_sort.

To set a field as a sort field, you create a sort table:


refresh gt_sort. 

clear gs_sort. 
gs_sort-fieldname = 'FIELD1'. 
gs_sort-spos = 1. 
gs_sort-up = 'X'. 
*gs_sort-down = 'X'.   " only do one of up or down, depending on desired sort order
gs_sort-subtot = 'X'.   "subtotal is optional
append gs_sort to gt_sort.

clear gs_sort. 
gs_sort-fieldname = 'FIELD2'. 
gs_sort-spos = 2. 
gs_sort-up = 'X'. 
*gs_sort-down = 'X'.   " only do one of up or down, depending on desired sort order
gs_sort-subtot = 'X'.   "optional
append gs_sort to gt_sort.

etc for as many sort fields as needed

Then to identify the fields to be subtotaled, set the DO_SUM attribute for each field in the field catalog that should be subtotaled:

gt_fieldcat-do_sum = 'X'.

You would add the sort table to you method call for SET_TABLE_FOR_FIRST_DISPLAY

    CALL METHOD g_alv->set_table_for_first_display
      EXPORTING
        is_variant           = gs_variant   
        i_save               = 'A'            
        is_layout            = gs_layout
        it_toolbar_excluding = gt_toolbar_excl
      CHANGING
        it_outtab            = gt_alv_grid_tab
        it_fieldcatalog      = gt_fieldcat
        it_sort              = gt_sort.

If you wanted to change the sort later under program control, you would call the method SET_SORT_CRITERIA

CALL METHOD g_alv->set_sort_criteria
  EXPORTING
    it_sort                   = gt_sort
*  EXCEPTIONS
*    NO_FIELDCATALOG_AVAILABLE = 1
*    others                    = 2

For SALV

  DATA: lr_sorts            TYPE REF TO cl_salv_sorts.
  DATA: lr_agg              TYPE REF TO cl_salv_aggregations.

      lr_sorts = gr_table->get_sorts( ).

      lr_sorts->add_sort( columnname = 'FIELD3'    subtotal = gc_true ).  "subtotal is optional for each field

Hi , thank you for the code , however the output remains unchanged.

I am using CL_GUI_ALV_GRID , had created the sort table the way you showed , and also passed it to the set_table_for_first_display ,, but there is no change inthe out put I also put the method go_grid->set_sort_criteria right after set_table_for_first _diplay , There is still no change. I am able to see the material numbers and the qunatity fields repeated.

Re: SORT IN ALV with Objects

Former Member — Thu, 13 Sep 2007 22:40:17 GMT

Krish, i have run into this problem with sorting on CL_GUI_ALV_GRID, where the merging feature does not work, regardless of the setting of the no_merging flag, and I do not have a solution for that.

In such cases, I have generally converted to SALV, unless I need input/edit features that SALV does not have, and in that case I just live with the unmerged cells.

While the answer that I gave above is the "textbook" correct answer for sorting with CL_GUI_ALV_GRID, it appears that problems with the merge feature in CL_GUI_ALV_GRID still exist.

There appear to be some bugs in particular releases related to ALV and cell merging.

For example, see

http://www.elec.ucl.ac.be/logistique/informatique/SAP/Manual-6.4r4/relnotes/new.htm

which highlight when bug fixes were released.

In particular note the following (for example):

Release 6.40 rev 2 (June 7, 2005)
Bugfixes

     * Grid control: 
          * The titlebar has not been displayed when the toolbar did not have any
             buttons. 
          * The methods SelectedRowsType2() and  SelectedRows2() were missing, 
             causing an ABAP dump in case they were called by the application. 
          * The wrong column was sorted after pressing the sort button in the toolbar. 
          * Rows can now be (de)selected by ctrl-click. 
          * Row selection buttons have been missing in some cases. 
          * Merging cells of several columns is now also supported for complete
             columns, not only for particular cells. 
          * In some cases, the background color of non-changeable cells has been
            wrong.
          * The new data of a currently edited cell now is sent to the application
             server. 
          * Reordering columns by Drag & Drop has not been reported correctly.

If you are on a release prior to the one specified, you may still have problems.

However, if you are doing output only, it should be relatively easy to convert to SALV. SALV is nice in that you don't have to handcode the field catalog.

Rich Heilman, who is a regular on SDN, did a nice write up on SALV, which is available on-line

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/webcontent/uuid/207dc670-6e8e-2910-3297-d1a1ae9c04e8 [original link is broken]

You can also use SE84, Info system and search for program examples starting SALV*

Good luck
