Is it possible to pass a field symbol as parameter from any method of view?

Hi
Is it possible to pass a field symbol as an importing parameter to teh globally declared attribute??

While it is true that you can pass field symbols, they must be fully typed at the time you pass them and they will be passed by value, not by reference. If you want to pass generically typed variables use a data reference (TYPE REF TO) instead.

Field-symbols as parameters to the method of a class

Hi All,
I am having an doubt regarding the field-symbols.Can we pass the field-symbols as a parameter to the method of a class.If yes can anyone tell me how to do this. Before posting I have searched regarding it in google but I did not find any better solution.Though I have seen some examples regarding the passing of field symbols as a parameter those scenarios does not match with my report as my report varies dynamically based on selection criteria.
Below is the snippet of my code regarding the passing of field-symbols as a parameter.
methods: final_data importing <fs_h_line>TYPE any
                                             <fs_h> TYPE STANDARD TABLE

                                             <fs_f> TYPE STANDARD TABLE,
CALL METHOD l_obj->final_data exporting <fs_h_line> = <fs_header_line>
                                                              <fs_h>      = <fs_header>
                                               importing <fs_f_line> = <fs_final_line>

With the above code I am getting an error.Check whether it is correct or not.If not suggest the solution to resolve the issue.

Maybe if you change this code below to field-symbol, it can work:

Is it possible to pass TABLE as the output parameter in stored procedure

Hey Experts,
Is it possible to pass TABLE as the output parameter in stored procedure.
eg
create procedure spGetData
@tableName as TABLE(intValue INT NOT NUL)
as

You can use OPENQUERY or OPENROWSET, as mentioned above, to make stored procedure results table like. There are
some limitations with these methods:
http://technet.microsoft.com/en-us/library/ms188427.aspx
In OPENQUERY this-sql-server-instance can be used instead of a linked server name. It requires setting data accces server option:
exec sp_serveroption @server = 'PRODSVR\SQL2012'
,@optname = 'DATA ACCESS'
,@optvalue = 'TRUE'

In webdynpro ,Passing field symbols as values to class methods

Hi
Please tell me the ways of accessing database in webdynpro abap(not directly). I am calling Class method for accessing database. As currently I am directly accessing database in my webdynpro application. I have created a class and method for the same.
In my method I want to use select statement which will return table with values to webdynpro application. So for select statement(Calling Method) I need to use my field symbol values as where in clause .
Could anyone please help with example code?
Thanks,
Ujjwal

data: in_line type ref to data.
CREATE DATA in_line LIKE LINE OF <dyn_tab>.
ASSIGN in_line->* TO <dyn_wa>.
You can create a data reference and assign it to a field symbol and change the values. direclty passing field symbols is not possible.

How to pass field symbol or table from one view to another view in abap web dynpro?

I am creating an Inbound Outbound ALV report in ABAP Web Dynpro. However at selection-screen I have select options and fetching is done at view2. Problem is we can pass parameter using inbound outbound parameters but how to pass internal table or field-symbols from one view to another view? I made use of Assistance Class too but its not very clear to me. Please give me some example or code to sort this problem out.

Passing unassigned field symbols to a method

Hello Gurus,
I work with a field symbol in a method and after the work is finished i have to use it i my program that i call the method from.
The problem is that the field symbol gets assigned only in the method so i can`t get the field symbol as a changing parameter in my method because it is not assigned yet.
I thought that i can return the field symbol from the method after it has been assigned, but i don`t know how. The <fs> is a dynamic itab that i created within the method.
Can anyone help please ??

Although already answered this code snippet might make it clearer
my_line is your data structure typically an itab structure.
For example
TYPES: BEGIN OF s_elements,
   tabname type DD02L-tabname,
   tabclass type dd02l-tabclass,
   as4user type dd02L-as4user,
   as4date type dd02l-as4date,
   as4time type DD02l-as4time,
   viewed(1) type c.
TYPES: END OF    s_elements.
Data: my_line            TYPE s_elements.
1) get the structure of your itab automatically so you can build an FCAT simply for any structure without the horrendous usual coding to manipulate and create FCATS.
CALL METHOD me->return_structure
       EXPORTING
            my_line = my_line.
You need to make a table ZOGT data available in the class definition either as an attribute if you are using the class builder SE24 or as DATA in the relevant class section.
data:
    zog         LIKE LINE OF lr_rtti_struc->components .
data:
zogt                    LIKE TABLE OF zog .
method RETURN_STRUCTURE.
lr_rtti_struc ?= cl_abap_structdescr=>describe_by_data( my_line ).
    zogt[] = lr_rtti_struc->components.
endmethod.
Your structure details are now in table zogt.
Use this to build an FCAT.
CALL METHOD me->create_dynamic_fcat
      IMPORTING
            it_fldcat = it_fldcat.
method CREATE_DYNAMIC_FCAT.
LOOP AT zogt INTO zog.
      CLEAR wa_it_fldcat.
      wa_it_fldcat-fieldname = zog-name .
      wa_it_fldcat-datatype = zog-type_kind.
      wa_it_fldcat-inttype = zog-type_kind.
      wa_it_fldcat-intlen = zog-length.
      wa_it_fldcat-decimals = zog-decimals.
      wa_it_fldcat-coltext = zog-name.
      wa_it_fldcat-lowercase = 'X'.
      APPEND wa_it_fldcat TO it_fldcat .
    ENDLOOP.
endmethod.
Now having got your FCAT you can build your dynamic table.
    CALL METHOD me->create_dynamic_table
      EXPORTING
            it_fldcat = it_fldcat
      IMPORTING
            dy_table        = dy_table.
(dy_table is defined as ref to data)
method CREATE_DYNAMIC_TABLE.
CALL METHOD cl_alv_table_create=>create_dynamic_table
       EXPORTING
            it_fieldcatalog = it_fldcat
       IMPORTING
            ep_table = dy_table.
endmethod.
Now populate your dynamic table as per sample code here
field_symbols:
<dyn_table>    TYPE STANDARD TABLE.
<dyn_wa>.
data: dy_line            TYPE REF TO data.
FORM populate_dynamic_itab.
ASSIGN dy_table->* TO <dyn_table>.
   CREATE DATA dy_line LIKE LINE OF <dyn_table>.
ASSIGN dy_line->* TO <dyn_wa>.
SELECT *
        FROM DD02L
        INTO CORRESPONDING FIELDS OF TABLE <dyn_table>
        WHERE TABNAME LIKE 'ZHR%'.
ENDFORM.
Now you can display your grid and process your data.
CALL METHOD z_object->display_grid
       EXPORTING
         g_outtab = <dyn_table>
         g_fldcat = it_fldcat
         i_gridtitle = i_gridtitle
         i_edit = i_edit
         i_zebra = i_zebra
       CHANGING
         it_fldcat = it_fldcat
         gt_outtab = <dyn_table>.
In the Method
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
    struct_grid_LSET-zebra = i_zebra.
    struct_grid_lset-grid_title = i_gridtitle.
    struct_grid_lset-ctab_fname = 'T_CELLCOLORS'.
    struct_grid_lset-stylefname = 'CELLTAB'.
     CALL METHOD grid1->set_ready_for_input
        EXPORTING
             i_ready_for_input = '1'.
    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 can even easily code your own column names if you so wish in the application program.
Before calling the method that displays the grid encode the following macro.
DEFINE col_name.
read table it_fldcat into wa_it_fldcat index &1.
wa_it_fldcat-coltext = &2.
wa_it_fldcat-outputlen = &3.
modify it_fldcat from wa_it_fldcat index &1.
END-OF-DEFINITION.
Then have a subroutine in your application code something like this
Form name_columns.
Here before displaying you can change the field catalog to
adjust your own column names.
*col_name col-nr 'your name' output length.
    col_name 1 'Table name' 30.
    col_name 2 'Table class' 12.
    col_name 3 'Changed By' 12.
    col_name 4 '    On'   12.
    col_name 5 '    At'   8.
    col_name 6 'Act' 3.
i_gridtitle = 'HR ESS / ITS ZHR Tables - Double click to display'.
i_zebra = 'X'.
i_edit = ' '.
endform.
Hope this clears it up a bit.
Once you get this stuff working you can re-use 99% of the code for almost any structure making the whole process of OO ALV grid applications really simple.
Yoy only need as well a standard dynpro with a custom container on it (se51).
Cheers
jimbo

Assigning a value to a field-symbol (workarea of type any)

Dear forumers,
I'm having a bit of difficulty in assigning a value to a field-symbol (it should be treated as a workarea of type any), but I'm given a syntax error instead:-
The data object "<LFS_WORKAREA>" has no structure and therefore no component called "LFMON".
What could have gone wrong and how may I resolve this (I must have missed something out)? I will still need <LFS_WORKAREA> to be defined as TYPE ANY.
Please help. I'd appreciate any inputs at all. Thanks.

Hi
I have a stand alone program (can be used by all other users) which will accept request_id and To_Email as parameters. I am developing a new request set in which I want to incldue this stand alone program and want to pass Prog#1 request Id to the 2nd stand alone program as a parameter so that I can send the output of the Prog#1 to the users through E-mail.
Do we have any options to pass Prog#1 requeset id in to Prog#2 as a parameter in the request set without modifying the stand alone concurrent program code.
Please note that i dont want to change stand alone program code becuase this code/program was developed to work in general for all the users and I dont want to change this code for new requirement/purpose...
Hope you understood my requirement...

String containing apostrophe sign passed to text field via binded parameter from XDP displayed wrong

Hello,
I have a text field that is bound to a String field in XDP, sometimes when the field contains apostrophe sign (') generated PDF displays ' instead, for example if the value is he's it shows he's
The field format is plain text only.
The problem only appears occasionaly and rarealy and I can't find the reason and can't even reproduce it anymore.
Maby someone has encountered such problem and know the reason why it happens or conditions for it to happen and the means to fix it?
