Hide columns with internal ID's in af:table using af:panelcollection

Hi,
I use a af:table within a af:panelcollection based on view object.
The default menu of panelcollection "View --> Columns --> Show more columns ..." allow the end-user to add all columns of the view object.
The view object contains internal ID's (which I need to have in the VO) I never want to show to the end-user.
Is there a declerative way to avoid this (e. g.: Hide menu item "Show more columns ..." or set attribute of VO to "very hidden")
regards
Peter

Hi,
since you don't want to show the columns, what about removing them from the table (from the structure window). Is this an option or not possible ?

Check which table has no column with specific name over number of tables

Hello,
Withing my schema I have 66 tables, all of them have column last_update_date. Though not all have the column program_update_date. The problem is I want to go through all the tables and know which tables does not have the program_update_date column. It is to be noted that if the table does not have the program_update_date column query 2 will be used instead of query 1.
query1:
select last_extract_date,
to_char(min(greatest(nvl(*last_update_date*,'01-Jan-10'),nvl(*program_update_date*,'01-Jan-10'))),'DD-MON-YY HH24:MI:SS') mi,
to_char(max(greatest(nvl(*last_update_date*,'01-Jan-10'),nvl(*program_update_date*,'01-Jan-10'))),'DD-MON-YY HH24:MI:SS') ma
from table_names
group by last_extract_date
order by last_extract_date desc;
query2:
select last_extract_date,
     to_char(min(nvl(last_update_date,'01-Jan-10')),'DD-MON-YY HH24:MI:SS') mi,
     to_char(max(nvl(last_update_date,'01-Jan-10')),'DD-MON-YY HH24:MI:SS') ma
     from mispa_events
     group by last_extract_date
     order by last_extract_date desc ;
Please find the PLSQL code that should be used:
Declare
cursor C_1 is
select unique table_name from user_tables; table_names varchar2(240); Begin Open C_1; Loop Fetch C_1 into table_names; EXIT WHEN C_1%NOTFOUND;
EXECUTE IMMEDIATE('select last_extract_date,
to_char(min(greatest(nvl(last_update_date,''01-Jan-10''),nvl(program_update_date,''01-Jan-10''))),''DD-MON-YY HH24:MI:SS'') mi,
to_char(max(greatest(nvl(last_update_date,''01-Jan-10''),nvl(program_update_date,''01-Jan-10''))),''DD-MON-YY HH24:MI:SS'') ma
from ' || table_names ||'
group by last_extract_date
order by last_extract_date desc');
End Loop;
Close C_1;
COMMIT;
End;
Please help.
Thanks in advance.

Hide columns with sql

I am creating a table where there is a column for the particular row to be hidden. What do I do to make that particular row to stay hidden?
Ex:
ID Name Hide
1 joe N
2 john N
Now after I edit the data of joe to Hide=Y I want the table to display:
ID Name Hide
2 john N
anyone know what statements i need to do? thanks

Here is one way. You could create a view for the table.
SQL> select * from mytable1;
        ID NAME                           H
         1 joe                            N
         2 john                           N
         2 harry                          Y
SQL> create view myview as
2   select * from mytable1
3   where hide = 'N';
View created.
SQL> select * from myview;
        ID NAME                           H
         1 joe                            N
         2 john                           N

Implementing dependent choice list with internal columns as varchar

Hi,
While implementing dependent choice list I created two tables & their views with internal column as varchar(for example: countryName for country table & stateName for states table) instead of int. I couldn't get the DCL working: selecting a value from the dropdown of parent field won't show up only the dependent values of the child field; it will display the dropdown with all values (it will show all values of the States irrespective of the countryname selection). However when I select the internal column as int & visible column as varchar the DCL works fine.
Our requirement is to use the internal columns as varchar instead of int. Please suggest/help.
Thanks,
Madhur

Hi Shashwat,
I have done that. The problem is: dependent choice list doesn't seem work is you choose primarykey/foreign key as varchar. It works if I choose the primarykey/foreign key as int. And this key will be the internal column in the views. My requirement is to have them as varchar so that while checking-in content using RIDC API I don't have to provide the int value.
Thanks & Regards,
Madhur

Hide Matrix column With Parameter

Hi
I,m trying to hide matrix columns with parameters. If i for example have one matrix column with for example tre metrix values (Jan, Feb, and Mar). I have an expression with the values Jan, Feb, Mar with witch i would like to decide which
columns to show in the matrix column. In cases when i have a real column i use code as below in the column. But now that this three columns basically exists in one matrix column i dont know how to solve it. Anybody that has a soluiton on this preferably
some example code on the example.
IIF(INSTR(JOIN(Parameters!ColumnChoser.Value,
","),"Jan")>0,False,True)
Best regards Arne
Arne Olsson

Why not restrict data to only show the months you passed. Matrix creates columns based on data available so what you need is a filter like this in query below
WHERE ','+ @MonthList + ',' LIKE '%,' + MonthName + ',%'
assuming @MonthList as parameter through which you pass Jan,Feb etc and MonthName is column of the table containing corresponding month names used as matrix column group.

Hi Guys,
I have built a template for FSG reports. Currently the FSG Reports when run in XML does pull the Display Sets definition for the report. The Display Set is used to hide certain row and Column intersections from the FSG.
So to accomplish this I have coded each column in the template to display data or hide data for a particular row by using the code
<?if:(position()) !=1?><?fsg:RptCell[2]?><?end if?> ------ This means, show the column for all rows except row 1.
Now there are some places I have to hide Column 1 for row 2 and row3 and display for row 1 and row 4.
Can anyone please tell me how I can accomplish this.
Thanks

ALV report with internal in field symbol

Hi Shifu ABAP,
I have ALV report.
My problem is when I tried to do sum using the sum icon. I got a message 'desired operation cannot be performed for column 'Dignostic delay'. Is it because I used field symbol, then when I clicked on the column it didn't recorgnise the field.
FYI.
1)The internal table for my ALV report is stored in field symbol.
2)I dont have a problem to display the report.
3)I had to set 'do_sum' at ALV field category, still doesn't work
My source code to define ALV category.
loop at i_qpcd into wa_qpcd.
CLEAR ls_fieldcat2.
ls_fieldcat2-col_pos = pos2.
ls_fieldcat2-fieldname = wa_qpcd-code.
ls_fieldcat2-reptext_ddic = wa_qpcd-desc.
ls_fieldcat2-just = 'C'.
ls_fieldcat2-do_sum = 'X'.
APPEND ls_fieldcat2 TO gt_fieldcat2.
endloop.
My source code call the ALV FM
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

     i_callback_program         = 'ZMPMR001_Q1OOT'
     i_callback_pf_status_set = 'PF_STATUS_SET'

Thanks a lot in advance for your attention.

my situation is like this, declare the internal tble
1) data : begin of itab occurs 0,
            code like qpcd-code,
            desc like QPCT-KURZTEXT,
          end of itab.
2) populate the itab like this
code           desc
01              desc 1
02              desc 2
03              desc 3
3) take the selected record converted it into new dynamic internal table using field symbol declare as table, now the component of this new table are 01, 02 and 03.
4) populate the new table with some data, so technically my new table structure will be like this
01         02         03
1           0          1
0           0          3
2           2          2
5) display the new table in ALV report, in ALV I tried to sum-up each of column.
6) Question : HOW can I convert the componet 01, 02 and 03 as an integer/numeric field.

Help with any of these will be appreciated.

1.         I have a security app on my computer, Flashbrief. I have it checked in the hide column but whenever I turn on the computerit appears in the top menu line.
I've never heard of this software, and cannot find any reference to it online, which is a bit concerning. What is it supposed to do? There really isn't much need for security software on a Mac.
2.         Whenever Iturn on the computer, a new blank document window in MS Word 2011 appears. I do not have this listed in the login items.
In Mac OS X 10.7, any applications left open when you shut down or restart are re-opened at startup, and any documents left open in an app when you quit are re-opened when you launch them again. The former can be controlled by unchecking the box in the restart/shutdown alert:
You will need to do this each time you shut down or restart, it won't remember that setting.
The latter can be deactivated by unchecking the box in System Preferences -> General:
3.         I have a current model of Apple wireless mouse. It keeps getting stuck in text or e-mails and I have to somehowotherwise move the cursor to break it free.
That does not sound normal, but I don't use a mouse with my MBP, so I can't provide a solution, other than to try replacing the batteries in the mouse.

I am having one internal table with one row. I know the column number. I want to read that particular column value. What should I add with the below statement.
Read table itab index 1.
This will give me the whole row. I want only the particular column.
Please help me to solve this issue
Thanks.

Hi,
FIELD-SYMBOLS <FS_ANY>
ASSIGN COMPONENT N OF STRCUTURE OF WORKAREA TO <FS_ANY>
WRITE <FS_ANY>
Where n is the column number and workarea is the row of the internal table.

Hide column in webreports (without table interface)

Hi,
I want to hide columns in my webreport only(!) with the context menu. The idea is to set a statement like "remove drill down" --> <SAP_BW_UR CMD='Expand' DATA_PROVIDER='View1'IOBJNM='0COUNTRY' >
The problem is that I don't which InfoObject is selected, because I'm changing the standard template. Is there a chance to get that information by clicking to the menu?
Hoping sb can help.
Barbara
