How do i prevent display of a particular column in ALV

How do i prevent display of a particular column
of a structure in ALV

Hi Serdar,
Please do let us know the link , as soon as your code sample is put in sdn.sap.com.
I request the veteran members of this forum to contribute to WebLogs or code samples, since over the time, the same questions will be asked and instead of repeating the answers, we can direct them to Weblogs or Code Samples.
There is an ABAP FAQ present in this site, which has given insight to so many things, that I have not even considered remotely possible.
As seen today, there was a useful piece of code posted. Instead of posting the code in the forum, you can create it as a weblog and post it there.
Regards,
Subramanian V.

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) .

Hi,
 Check the following code.
TYPE-POOLS: slis.
TYPES:
 BEGIN OF ty_output,
 chk TYPE c,
 number TYPE i,
 name(20) TYPE c,
 END OF ty_output.
DATA: gt_output TYPE STANDARD TABLE OF ty_output,
 gs_output TYPE ty_output.
DATA: wa_layout TYPE slis_layout_alv.
DATA: it_fieldcatalog TYPE slis_t_fieldcat_alv,
After you populate the data, build the field catlog like shown below.
wa_fieldcatalog TYPE slis_fieldcat_alv.
wa_fieldcatalog-fieldname = 'CHK'.
wa_fieldcatalog-outputlen = '3'.
wa_fieldcatalog-col_pos = '1'.

wa_fieldcatalog-edit = 'X'.
APPEND wa_fieldcatalog TO it_fieldcatalog.
wa_fieldcatalog-fieldname = 'NUMBER'.
wa_fieldcatalog-outputlen = '10'.
wa_fieldcatalog-col_pos = '2'.
wa_fieldcatalog-seltext_m = 'NUMBER'.
APPEND wa_fieldcatalog TO it_fieldcatalog.
CLEAR wa_fieldcatalog.

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

How do you prevent display glitches with multiple while loops.

I would like to use 2 while loops, 1 for displaying elapsed time and the other for executing a sequence of initialization steps. Every time the sequence transistions from one frame to the next, I get a glitch in the elapsed time display. How can this be avoided? Should I be going about this in a different way?

I would drop the whole semaphore thing and hold the cluster in a functional global (also called a shift register database or LV2-style global, you can find info on the concept here). Add methods to update different parts of the cluster. Much easier code and the required protection of the cluster is there.

Display one or more rows for a particular column in alv grid display

Hi,
My requirement in the report is to display users for a particular workitem id.If a workitem is in the inbox of one or more users(approvers) i have to display all the user names in one field in alv grid output (output-approver id).There are other fields which display details of the workitem also.
Is there a way to populate multiple rows for a single column or creating one more internal table for users in the alv output table.
Please suggest.
regards,
Sravanthi Chilal

ALV only can show flat internal table data.
you should set a sort on the field which you want to show only once.
Then on the output of the ALV, the field with the same value will show only once.

Hi,
see " Accessing the content of a selected table row" in http://thepeninsulasedge.com/frank_nimphius/adf-faces-rich-client-javascript-programming/ to get an idea. Note that the af:column child must have clientComponent=true set in its properties

Hi Gurus! how to count number of records in any column of ALV Grid report

Hi Guys!
I want to know how can we count the number of records in any column selected by the user. Like for oe customer there might be 20 sale order that means for 10 customer there will be 200 Sale order. So if i select cutomer number column ti should give 10 out put and whern select sale order it should give 200 as output.
-Anurag Jain

Hi,
Either you can use the hotspot_click event or double_click to show the Pop-up info of the Sales Order count or customer Count depending on the selection.
In the hotspot_click event method you have E_ROW_ID E_COLUMN_ID..using these you can find the Sales Ordert or customer Number.. Loop the internal table and find the Count.
In the double_click event method you have E_ROW E_COLUMN..using these you can find the Sales Ordert or customer Number.. Loop the internal table and find the Count.
