User Function in Fullscreen ALV

Hi guys,
i'm using a fullscreen ALV (CL_SALV_TABLE) and want to add a user defined function. On halp.sap.com i found a hint that i have to copy the GUI-STATUS SALV_TABLE_STANDARD and add that copy to ALV by using the method SET_SCREEN_STATUS.
Now the new Button appears, but here is my question. Where do i have to put my coding for that function?
Normally i catch function codes within user_command, but how to do that with fullscreen ALV?
Hope someone can help me?
Regards
Mark-André

Hi,
Chek this article [ALV Object Model u2013 Simple 2D Table u2013 Event Handling|https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/cda3992d-0e01-0010-90b2-c4e1f899ac01&overridelayout=true]. It explains it well.

Hi,
U can define it the the PF-STATUS ( Menu for ALV ).
For that u have to define it in the EVENTCAT.
form z_eventcat using    p_i_eventcat type slis_t_event.

Custom Function on OO ALV Grid

I am trying to implement ALV_GRID_XT to enhance the ALV Grid toolbar by adding couple of custom funcitons.As per the SAP documentation I have created 2 methods ON_TOOLBAR - one for adding items on toolbar and the other ON_USER_COMMAND - for processing if the user clicks on the custom function.
I am unable to relate the ALV Grid instance onto the method ON_USER_COMMAND . One of the funciton is to calculate the average of column which represents percentage excluding cells with zero values. Once the user selects column(s) and clicks on the Percent button on the ALV grid my piece of code should trigger ON_USER_COMMAND and then display the average percentage on the Totals row.
Method ON_USER_COMMAND has only one parameter E_UCOMM which i am able to get in the method but I am not able to get the instance of the ALV grid so that I can play around with the data in the Grid.
I could have used a local class and then enhanced the ALV toolbar but this requirement is needed for about 20 reports and hence thought of implementing it globally.
Any ideas would be appreciated.

Hi there
You need to set the handlers of course and register the events
I'm using also a Z-class using functionality from the ALV Grid
in the application program
data: z_object type ref to zcl_*      "my z_class"
* Instantiate your Z class
create object z_object
       exporting
                  z_object = z_object
                  cfname = 'CCONTAINER1'.
Now in your Constructor for your Z-Class have a variable
say grid1 which is defined as a type ref to cl_gui_alv_grid.
Code the methods you require --. The trick is to instantiate your OWN Z class and within YOUR CLASS instantiate the GRID1 variable as an instance of cl_gui_alv_grid - then you can use methods etc from that class in your own Z class simple via something like this
method CONSTRUCTOR.
create object grid_container1
        exporting
    container_name = cfname.
    create object grid1
       exporting
          i_parent = grid_container1.
    set handler z_object->on_user_command for grid1.
    set handler z_object->on_toolbar for grid1.
    set handler z_object->handle_data_changed for grid1.
    set handler z_object->handle_data_changed_finished for grid1.
    set handler z_object->on_dubbelklik for grid1.
    set handler z_object->on_hotspot for grid1.
    call method grid1->register_edit_event
        exporting
           i_event_id = cl_gui_alv_grid=>mc_evt_enter.
endmethod.
method display_grid .
get reference of g_outtab into g_outtab1.
     get reference of g_fldcat into g_fldcat1.
    struct_grid_lset-edit = i_edit.    "To enable editing in ALV
    struct_grid_lset-zebra = i_zebra.
    struct_grid_lset-cwidth_opt = i_opt.
    struct_grid_lset-grid_title = i_gridtitle.
*    struct_grid_lset-ctab_fname = 'T_CELLCOLORS'.
*    struct_grid_lset-stylefname = 'CELLTAB'.
     struct_grid_lset-ctab_fname = style_fname.
     struct_grid_lset-stylefname = style_ctab.
*     export gt_outtab from gt_outtab to memory id 'gt_outtab'.
    call method grid1->set_table_for_first_display
       exporting
             is_layout       = struct_grid_lset
       changing
             it_outtab       = gt_outtab
             it_fieldcatalog = it_fldcat.
endmethod.
You need to add the buttons to the toolbar with your ON TOOLBAR method
for example
method on_toolbar .
type-pools icon.
clear ls_toolbar.
     move 0 to ls_toolbar-butn_type.
     move 'EXCEL' to ls_toolbar-function.
     move space to ls_toolbar-disabled.
     move icon_xxl to ls_toolbar-icon.
     move 'Excel' to ls_toolbar-quickinfo.
     move 'EXCEL' to ls_toolbar-text.
     append ls_toolbar to e_object->mt_toolbar.
    perform   toolbar in program (caller) if found
     using e_object.
endmethod.
Now the functionality should work in the ON_USER_COMMAND .
Here's my ON_USER_COMMAND method within the class
method ON_USER_COMMAND.
*        FOR EVENT before_user_command OF cl_gui_alv_grid
*        IMPORTING
*          e_ucomm
*          sender
* When defined in SE24 you don't need to code the
* FOR EVENT etc as this is already defined as an event handler
case e_ucomm.
      when 'EXIT'.
        leave program.
      when 'EXCEL'.
       call method me->download_to_excel.
      when 'SAVE'.
      when 'PROC'.
        call method me->process.
      when 'REFR'.
        call method me->refresh.
        when 'SWITCH'.
        call method me->switch.
       when 'TEST'.
        call method me->get_cell.
       endcase.
endmethod.
Add whatever extra functionality you want to the on_user_command so long as you've defined toolbars..
Cheers

Function key in ALV output

hi all,
i have to make a function key(Re-process) in ALV grid output and if user selects any ALV row and click on that function key then it will reprocess the selected data. so can any one please tell how would i make Function key in ALV output and also how to trap the selected row data of ALV?
regards.

For this you will have to write the a Call back routine you will have to add a custom button in allv
and when your added button is pressed then this routine will be triggred you will have to write a operation for the function code inteh call back routine
you Get the CALL BACK ROUTING NAME PARAMETER in the REUSE_ALV_GRID_DISPLAY
in this routine you will ge the current selected row also.

Control User Specific button in ALV report

Hi,
Can anybody please suggest me how to control "USER SPECIFIC" button in ALV report layout using authorization object. I mean if you can tell me which authorization object is responsible to control the "USER SPECIFIC" button.

additional info to what Lakshmi already said:-
normally the restrictions for saving layouts/display variants are done at 2 levels:
1) The developer of an ALV list first predetermines the authorization in the 'i_save' parameter within the code.
I_SAVE = ' '     -
layouts cannot be saved
I_SAVE = 'A'   -
user-specific and cross-user layouts can be saved
I_SAVE = 'X'   --- cross-user layouts can be saved
I_SAVE = 'U' --- user-specific layouts can be saved
2) The second level comes to us restriciting the S_ALV_LAYO which gives access to users to save global layouts if I_SAVE for that particular transaction is A or X.
for example, a report has I_SAVE= 'A', which means
it will allow to save User-specific layouts without any restrictions.
and if user has S_ALV_LAYO then he can save both User-Specific and Global Layouts(variants).
it would be better to keep this object separate.

Problem while using a user function

Hi,
I just want to learn how a user function in ODI works.
I have created a user function(for Oracle technology).
In Definition Tab, I gave bfun($(branchc))
In implementation I gave
if ($(branchc) = 'it' || 'cse') then
return('IT')
else
return('Non-IT')
end if
In a mapping rule i am using it as BFUN(STUDENT.BRANCH)
I am getting the following error...
Bad Query: ORA-00904: "BFUN": Invalid Identifier
select BFUN('STUDENT.BRANCH') from EX.STUDENT STUDENT where (1=2).
EX is my source schema.
Please help me in resolving this.

Hi,
That is a common error on ODI.
The ODI function, (as ODI variable) is to "substitute words", it means, ODI is a code generator and a function are made to substitute code, not to "execute" that action coded.
For instance: If there are a "case when" instruction that is necessary be typed over and over again, at several places just change the column to be evaluate, you can create a ODI function to substitute this code avoiding type it several times and better, let the same code in just one place.
Is a way to have “Object Orientation” coding (OO) to code generation...
Does it make any sense to you?

Incorrect Results When Using an In-Line View and User Function in 10g

My developers are complaining of incorrect Select statement results when using an in-line view along with a user defined function. Below is the statement:
select test_f(wo1)
from
(SELECT a.WORK_ORDER_NBR, b.work_order_nbr wo1/*, facility_f(A.FACILITY),
A.PLANNER, A.WO_STATUS, mil_date(A.WO_STATUS_DATE)*, A.WORK_ORDER_TYPE,
A.WO_DESCRIPTION
FROM TIDWOWRK A, TIDWOTSK B
WHERE B.WORK_ORDER_NBR(+) = A.WORK_ORDER_NBR))
where wo1 is null;
Test_f() is a user defined function and the above query returns thousands of rows. It should return 308 rows. It is apparent that the target database is not evaluating the "where wo1 is null;" clause.
select to_char(wo1)

where wo1 is null;
In the above query return 308 rows. The user function was replaced by an Oracle function. The Where clause is now evaluated correctly.
The query is executed from an Oracle 10g R2 database and retrieves data from a 9.2.0.6 database.
I've seen a little information on Metalink. It appears that there was some trouble in 9i, but were fixed in a 9.2.0.6 patch. I don't see any information about a 10.2.0.2 database.
Anyone have any experiences or a successful solution. I suspect that I will need to report this to Oracle and wait for a patch.
Thanks,
John

I can only think of two reasons for this behaviour:
1) You are executing these two queries from two different users and there is some policy on the table.
2) The function doesn't do an upper, but returns null a lot of times, even when the input is a not null value, like this:
SQL> create table tidwowrk
2 as
3 select 1 id, 'A' work_order_nbr, 'DST' facility from dual union all
4 select 2, null, 'TRN' from dual union all
5 select 3, 'C', 'DST' from dual
6 /

SQL> create table tidwotsk

Using the Dollar($) Sign in a User Function Implementation

Hi All,
Just a quick question: how could you use a dollar($) sign in the implementation (Oracle) of a user function? I'm asking because the table name that I'm using in the implementation happens to contain the dollar sign (I$_FACT_SALES) and from the results I'm getting now, ODI reads the $ as reference to a variable, therefore removing the $-sign from my table name upon execution (I_FACT_SALES). Is there something like a backslash or some other character that could be inserted before the $ so it would register as part of the table name?
Any response would be greatly appreciated.
Thanks very much,
Marco

You may have 3 options:
1.) Try using the tablename in quotes "MY$TABLE" or may be MY$$TABLE using double $ symbol
or
2.) I found this code snippet : odiRef.getInfo( \\u0022DEST_WORK_SCHEMA\\u0022 )+\\u0022.\\u0022,\\u0022\\u0022)?. So on these lines you can use \\u0022 as a symbol for "
You can see similar problem/solution/explanation in
Re: Regular Expression wierdness - problem with $ character
or
3.) Change the Work Tables Prefix in Topology Manager > Physical Schema > Your_Schema
from E$_ , C$_ , I$_ to something like ERR_ , SRC_ , INT_

Using PL/SQL code in ODI User Functions

Is it possible to write PL/SQL code (with multiple in params and one out param) in ODI User Function ?
Actually I need to use this user functions in my interface mapping.
I know it can be done using ODI Procedures but Procedures cannot be used within interfaces when mapping columns.

Hi Anurag Ambasta,
You can use the ODI user functions and choose the Linked technology as 'Oracle' where you can implement and use oracle syntax .
And the user functions can receive the multiple parameters and it returns the single value to the function cal, which use are expecting right?
Thanks,
Yellanki

Calling user function from Interface mapping

I am getting error "Bad query:ORA-00904: invalid identifier" while calling function in the mapping of an interface.
Can some one provide the syntax of calling user function from interface mapping.
Thanks,
RP

Can some one provide the syntax of calling user function from interface mapping.Oracle's Call Iinterface, the OCI, does not work differently when coding using a Dvorak keyboard, or writing code using a pretty pink font in the editor.. or coding the call from an interface mapping (whatever the hell that that is).
You have 2 types of calls. SQL and PL/SQL.
To call a function via SQL, it can be done using a the standard cursor interface. E.g.
select MyFunkyFunction from dualIt will return the function value via a single row with a single column. The standard cursor fetch and close cursor calls are used.
To call it via PL/SQL, an anonymous PL/SQL block is needed, and the caller needs to use a bind variable to receive the value from the function. The anon block will look as follows:
begin
:bindVar := MyFunkyFunction;
end;Refer to your client's abstract layer for interfacing with the Oracle Call Interface, on how to deal with bind variables.

HOW TO USE FUNCTION MODULE IN ALV

hi guyz
I developed an alv report using join statements .But i got all that fields in a function module. so how can i use function module in alv .
if i got a function module with all the fileds do i need to use select statement.
plz help me.
thanks
sudheer

Hi,
Hope the following helps..
1)
LOOP AT IT_OUTPUT.
Call the function module to get the tracking number and store the output in the
variable V_TRACKINGNO.
IT_OUTPUT-TRACKING_NO = V_TRACKINGNO.
MODIFY IT_OUTPUT TRANSPORTING TRACKING_NO.
ENDLOOP.
2) Date conversion
DATA: V_CHAR(10) VALUE '2006.11.17'.
DATA: V_DATE TYPE SYDATUM.
CONCATENATE V_CHAR(4) V_CHAR5(2) V_CHAR8(2) INTO V_DATE.
WRITE: V_DATE TO V_CHAR MM/DD/YYYY.
WRITE: / 'MM/DD/YYY Format - ', V_CHAR.
Please make sure to reward points for helpful answers..
Thanks,
Naren

User function code not substituted

Hi
I have a user function (getCode(...)) of the form
case
when exists (select * from ...)
then '!Ok!'
else '!None!'
end
When I use this function in a interface mapping (getCode(a,b,c)), the code is not substituted in the generated query (as seen in the operator):
insert /*+ APPEND */ into ...
     Z_CODE,
     RUN_NR,
     REC_ID
select
     getCode( NAME, 'ZIV', 'G' ),
     RUN_NR,
     REC_ID
from     ...
where     (1=1)
and the execution results in an ORA-00904 exception: Invalid column name.
How come?
Thanks

First of all, thanks for your answers!
The problem was lying in the definition of the function's syntax:
I'm using the possibility to specify the data_type of the arguments: getCode($(run_nr)n, $(tabi)s, $(code)s).
Unfortunately, I put a space between the arg_name and the data_type! This causes the function not to be substituted into the query ...
Once again thanks to all.
Cheers, Benno
