Concatenate columns in ALV

Hi All
I am using CL_SALV_GRID class to cretae ALV. Column size limit in this alv is 128. my daya data is of size 255 chars.
Can we concatenate 2 columns of 128-128 length each in ALV display with single column header.
Please suggest.
Thanks and Regards
Aditya

Hi Aditya,
when ever u design a layout just provide the attribute to the ALV layout
p_it_layout-colwidth_optimize = 'X'.
where p_it_layout is the internal table of layout type i.e. slis_layout_alv.
this shall optimised the col width, auto ,.....
or have a look at the link
[Alv column problem.]
i hope this works !!!
Best of Luck !!

Hiding empty columns in ALV

Hi all,
I want to hide some columns in ALV which are empty on display when calling
cl_gui_alv_grid->set_table_for_first_display
That is to say the internaltable will contain empty columns.
I know that using the "no_out" attribute of field catalog we can hide columns.
But the question is how to find these columns which are empty - should I have to loop through the itab to find it out OR
Can we set it in ALV LAYOUT or field catalog attributes so that it wont display empty columns.
any help is appreciated....
Thanks

Display more than 1023 Columns in alv

can we display more than 1023 columns in alv. please provide inputs on any approach that can be followed to achieve this.
Thanks.

Hi,
just for the record. Here's the code to create a table with 10000 columns, in this example all of type vendor. It could be modified a little to create any dynamic table. Without any visible limits and can be displayed in SALV.
DATA:
    lv_lifnr       TYPE lifnr,
    lv_numc7       TYPE numc7,
    lt_components TYPE cl_abap_structdescr=>component_table,
    lo_struc_descr TYPE REF TO cl_abap_structdescr,
    lo_tdescr      TYPE REF TO cl_abap_tabledescr,
    lr_tab         TYPE REF TO data.
FIELD-SYMBOLS:
    <component>   TYPE LINE OF abap_component_tab,
    <range_tab>   TYPE STANDARD TABLE,
    <tab>         TYPE table.
* build dynamic table
DO 10000 TIMES.
    APPEND INITIAL LINE TO lt_components ASSIGNING <component>.
    <component>-type ?= cl_abap_datadescr=>describe_by_data( lv_lifnr ).
    lv_numc7 = sy-index.
    CONCATENATE 'FIELD' lv_numc7 INTO <component>-name.
ENDDO.
lo_struc_descr    ?= cl_abap_structdescr=>create( lt_components ).
lo_tdescr        = cl_abap_tabledescr=>create( lo_struc_descr ).
CREATE DATA lr_tab TYPE HANDLE lo_tdescr.
ASSIGN lr_tab->* TO <tab>.
APPEND INITIAL LINE TO <tab>.
I discovered that it takes some time (15 seconds or more) to create, even F1 and F4 in the SALV table use considerable time to pop up, I think (SAP never imagined
But it works - and the code is so simple!
Kind regards,
Clemens

Please go through the below   code and do the same   for appearing the   four fields of different table into One Field catalog at   Display by Concatenating .
DATA :v_tmp type string .
Loop at itab1.
Read table itab2 key field1 = itab1-field1 .
Read table itab3 key field1 = itab1-field1 .
Read table itab4 key field1 = itab1-field1 .
Concatenate itab1-field1 itab2-field1 itab3-field1 itab4-field1 into v_tmp.
fieldcatalog-fieldname   = 'V_TMP'.
fieldcatalog-seltext_m   = 'Item change date'.
fieldcatalog-col_pos     = 1.
append fieldcatalog to fieldcatalog.
clear fieldcatalog.
endloop.

Merging Two Columns in ALV

Hi Experts,
I have a requirement, and I need to merge the the two columns in ALV. How can I do this?
Points will be rewarded for helpful answers.
Thanks in advance...

Hi Salem
Check this sample code
LOOP AT itab.
CONCATENATE itab-amount itab-currency INTO itab-combined.
MODIFY itab.
ENDLOOP.
You will probably need to embellish just that concat command as all fields will be treated as TYPE C.
Then inhibit the display of the original fields amount and currency by setting NO_OUT=X in the fieldcat loop (or other method).
There may be a FM to merge/format amounts and currency but I couldnt find one on quick search.
The option 'USING EDIT MASK' from WRITE command is also available in ALV structure IT_FIELDCAT.
I have only used it in write and for simple stuff, but it may have some options for you.
Check '==conv' for output conversion routine...
Reward all helpfull answers

How can i suppress columns in ALV ?? Will reward points.

Hello Gurus, how can i suppress column in ALV when i`m using the transparent table:
CALL METHOD grid->set_table_for_first_display
      EXPORTING
        i_structure_name = 'ZIANEXE'
        is_layout        = wa_layout
        is_variant       = wa_variant
        i_save           = 'U'
        IT_TOOLBAR_EXCLUDING = LT_EXCLUDE
      CHANGING
        it_outtab        = itab[]
        it_fieldcatalog = fieldcat.
Please help.

in the fieldcatalog you are providing there is a field NO_OUT use this.
Loop over internal table and check fieldname. If fieldname = column you want to hide, NO_OUT = 'X'.

Hi
As far as i know you can't do this,the option you have is to create one more column (subtotal) and populate it by manual calculation at every subtotal (not alv subtotal but yours) .

Thanks,

Hi Vikranth,
I am displaying one ALV list say with columns A and B.
I have value in A but not in B. Now at runtime user selects one row, clicks on push button in application toolbar, then i have to display value in column B in the already displayed list.
I searched and came to know it can be done with oops concept. but i am not using classes and methods.
so how can i do this?

SAPGUI JAVA 7.10 (OSX 10.5.1): cannot select multiple columns in ALV

Hi,
in sapgui java 7.10 (on mac osx 10.5.1) I cannot select multiple columns in ALV reports.
I can do it only in some transactions (like SE16). But on all our custom reports (REUSE_ALV_GRID_DISPLAY) in does not work.
Any hint?
Many thanks,
Lorenzo

Hi Lorenzo,
did you double check if selecting multiple columns works with SAP GUI for Windows in the same report?
If yes, I suggest to file a bug report so we can do a remote logon to run your custom report.
If not it might be because of REUSE_ALV_GRID_DISPLAY itself or your parameters calling REUSE_ALV_GRID_DISPLAY.
Best regards
Rolf-Martin

Maximum number of character we can print in a column uing ALV grid display

Hi frnds,
My requirment is to print 500 charcter data in a column using ALV grid display.
Could any body tell me is it possible and the maximum character it can i print in a column using ALV grid dispaly.
Regards,
Sandipan

Hi Sandipan,
refer notes 857823, 910300 and 959775. All these say there is a limitation of 128 characters.
857823 - ALV grid: Strings with a maximum of 128 characters
Symptom
Entries in cells of the type CHAR or string are truncated after 128
characters in the SAP GUI.
also refer,
ALV Grid Control (cl_gui_alv_grid), function module (Full-screen) Grid
(Reuse_alv_grid_display, SAPLSLVC_FULLSCREEN), SAPGUI, back end, front end
Cause and Prerequisites
The data table that is sent to the front end only allows character values
with the length 128.
Solution
This is the standard system behavior and cannot be changed.
