Field-symbols as class attribute

Hi Fellas,
Is there a way we can define a field-symbols as a class attribute ? My requirement is that i am dynamically constructing a structure at runtime in my model class and binding the component of this structure to my view fields. I am able to create the structure which is basically ref to cl_abap_structdescr and the problem is when i am binding to the model attribute, i need this to be a structure so that i can address the components as "//model/structure.component".
Please let me know how we can define a field-symbol as a class attribute.
Cheers,
Ram.

Hi Ram,
Field-Symbol as class attribute is not possible. Your way to do this by REF TO DATA is the correct way for that.
By default data binding is only possible like this:
Simple field attribute
value=//<model>/<field name>
Structure attribute
value=//<model>/<structure name>.<field name>
Table attribute
value=//<model>/<table name>[<line index].<field name>
If you want to bind to your data reference you have to implement your own getter and setter methods. Read this <a href="http://help.sap.com/saphelp_nw70/helpdata/en/fb/fbb84c20df274aa52a0b0833769057/frameset.htm">http://help.sap.com/saphelp_nw70/helpdata/en/fb/fbb84c20df274aa52a0b0833769057/frameset.htm</a> for further information. In addition to that, you have to implement your own GET_M_S_xxx to return metadata of your structure. By doing all this it is possible to implement a completely dynamic data binding. In the view it looks like the regular Structure attribute: value=//<model>/<data-ref name>.<field name>

Field symbols as Class Attributes

Hello Gurus,
Is anybody able to say to me if it is possible to declare field symbols as class attributes? As I can understand until now, this is not possible and we need to use some attribute with the "TYPE REF TO Data" to get the information we need. Correct?
Thanks,
Daniel.

As you can see, I am repeating almost the same code, just changing some items. I am not sure if I can use new parameters (ANY or ANY TABLE) but, my first idea to improve it was to use the field-symbols (and it works ok). The issue is that I have to repeat the assignment lines every same named method of the classes I am changing (I would like to do the assignment into a new method of the superclass). Do you think it is possible or should I give up and proceed with the assignments locally, for each same named method of each class?
Thanks,
Daniel.

Very Urgent: how to define field symbols in class using se24 Points assured

hi all
I am new to abap oo programming. I am using se24 to build a class
where some methods have code which involves working with field sybmols but i am not able to figure out way for how to define field symbols in the attributes section.
I tried defining like : fld_sym type ref to dbtab-fld
but in the method implementation if i try to use it like assign fld to <fld_sym> there it says fld_sym is not defined as a field symbol.
So can anyone please guide me how to define field symbols in se24.
Also what should be the general steps while creating a class using se24.
Points assured
thanks

Hi
Global classes are like Global fun modules in which the Methods and code is already written and is mainly used for Reusability purpose.

Field symbols inside class

Is it possible to declare field symbols inside classes?
Thanks in advance.
Hema
Moderator message: please search for information and try yourself before asking.
Edited by: Thomas Zloch on Dec 23, 2010 10:55 AM

Hi Hemalatha,
We can use Field Symbols in classes.
local field_symbols within methods are allowed.
you can only use field-symbols within method (locally), not as direct class attribute (globally).
U can check with this sample code.
Sample code is given below:
CLASS c1 DEFINITION.
PUBLIC SECTION.
METHODS m1 IMPORTING oref TYPE REF TO object attr TYPE string.
ENDCLASS.
CLASS c1 IMPLEMENTATION.
METHOD m1.
FIELD-SYMBOLS <attr> TYPE ANY.
ASSIGN oref->(attr) TO <attr>.
WRITE <attr> ...
ENDMETHOD.
ENDCLASS.
I hope u got this .....

Field-symbols in classes

Hello,
Is it possible to use field-symbols in classes?
When I try to declare field-symbol in class like other variable, appears an error.
Or may be it is possible to use something instead of field-symbols?
Great thanx in advance!

Model Binding and Calculated Field Syntax for "class" Attribute

Hi,
I tried to use the calculated field syntax from SAP UI5 to change the CSS class attribute of an element based on some model property, i.e., I wanted to change the class in the corresponding formatter function based on the currently bound value. However, my formatter function is not called. When I use the same syntax on a text attribute, it works.
I also tried to use normal property binding, but it did not work on the class attribute either (it just put class="{property}" in the rendered HTML).
Is there anything I missed or is it just not possible to use property binding and calculated field syntax for class attributes? Did anybody try something like this before?
I think it is a standard use case to change the CSS class based on some model property. So, if anybody knows how to do that, could you give a short example?
Best regards
Svenja

They have a class property. At least, I can do the following in an XML view:
<Button
              icon="sap-icon://add"
              press="onButtonPress"
              class="my-button-class" />
I would expect the following to work as well, but for me it did not:
<Button
              icon="sap-icon://add"
              press="onButtonPress"
              class="{/customClass}" />
This renders the following HTML (cropped to the important parts):
<button type="button" class="sapMBtn {/customClass}">
</button>
It seems like the class attribute is something special although I don't see a reason why. Other HTML templating engines, for example, support things like that.

Field-symbols as pgae attributes?

Hi all,
i have the problem of including a page fragment two times in the same page. In this fragment i declare a field symbol. And when i try to compile the code it crashes.
I need to declare it somewhere, so that just one declaration have to take place. I suppose as a page attribute is the correct step. But i don't know how to do that. Could anyone help me or give me an other possible solution to my problem.

Hi,
In the assumption that you have defined a table called itab.
In your page:
<%FIELD-SYMBOLS <fs> TYPE ANY TABLE.%>
<%@ include file = "pagefrag.htm" %>
<%@ include file = "pagefrag.htm" %>
in your page frag:
<%ASSIGN itab TO <fs>.%>
That's it, it works fine.

Field Symbol as Global Data

Hi, can a field symbol be global in a static class?

Hello Kenneth
Please refer to the answer of Klaus Ziegler in the following thread
Re: Field symbols as Class Attributes

Uwe

Field Symbol Assignment

Hi,
I have a doubt regarding the field symbol assignment.
In my program, I have logic as below.
<b> W_1STCNTFLD = 'E_INV_AGING_STRU-PDISCCNTP1'.
W_2NDCNTFLD = 'E_INV_AGING_STRU-PDISCCNTP2'.
ASSIGN (W_1STCNTFLD) TO <FS1>.
ASSIGN (W_2NDCNTFLD) TO <FS2>.</b>
While debugging, when I see the values of the Field Symbols <b><FS1></b> and <b><FS2></b> after assignment, they are <b>0, 0</b>. Why is it like that..?
In general, what does a Field Symbol hold..? the value of the variable being assigned or the Memory location of that variable..?
When I remove the paranthesis while assigning like below,
<b>ASSIGN W_1STCNTFLD TO <FS1>.</b>
it is storing the value of the variable(<b>E_INV_AGING_STRU-PDISCCNTP1</b>) to <b><FS1></b> instead of '0'.
And what is the difference between   <b>ASSIGN (W_1STCNTFLD) TO <FS1></b> and   <b>ASSIGN W_1STCNTFLD TO <FS1></b>..? I mean, when we put paranthesis to the variable and when we remove the paranthesis.
Please clarify my doubts. Thanks in advance.
Thanks & Regards,
Paddu.

when you use the paranthesis,(W_1STCNTFLD) actually equals to ('E_INV_AGING_STRU-PDISCCNTP1'),and the 'E_INV_AGING_STRU-PDISCCNTP1' must be the label of a data object,it can't be a string!
please refer to the following document(coming from sap abap keywords document):
Alternative 2
... [TABLE FIELD] (name)
Alternative 3
... oref->(attr_name)
Alternative 4
... {class|(class_name)}=>{attr|(attr_name)}
Effect
There are three dynamic variants for mem_area, where the storage area is not specified directly, but as the content of character/type data objects enclosed within parentheses.
In the first variant (name), the label in name is built exacltly like the direct specification. When the statement is executed, the content of name must be the label of a data object that can contain offset/length specifications, strucuture component selectors, and component selectors for the assignment of attributes in classes or objects (since Release 6.10). The content of name must be specified in uppercase letters.
The optional addition TABLE FIELD before (name) is only possible outside of classes. This addition limits the search area - where the data object specified in (name) is searched for (see below) - to the interface work areas for the current program group declared using TABLES. If TABLE FIELD is specified, casting_spec and range_spec cannot be specified explicitly.
If the label in name is a field symbol or a form parameter with an unstructured type, components can be addressed, as of Release 6.10, through structure component selectors. The components must exist when the statement is executed.
The second variant oref->(attr_name) is a special case of the first variant for the assignment of an instance attribute to a field symbol - where the object reference variable oref is specified statically. The label of the attribute is specified dynamically in the character-type field attr_name and must not be specified in uppercase letters.
The third variant {class|(class_name)}=>{name|(attr_name)} is a special case of the first variant for the assignment of a static attribute to a field symbol where the class name class and the name of the attribute name can be specified both directly and dynamically in character-type fields class_name or attr_name. The contents of attr_name and class_name do not have to be in uppercase letters. If the class name is specified dynamically and the attribute is specified directly, no offset/length specifications can be made for the attribute.
If a data object is specified dynamically, this is searched for in accordance with the following hierarchy.
Within the local data objects of the current procedure
Within the attributes, visible in a method, of the actual class, where , in instance methods, the self reference me-> is set explicitly before the label
Within the global data of the current program
Within the interface work areas of the main program of the current program group declared with TABLES
Within the attributes of the object to which oref refers, if the label has the expression oref-> (as of Release 6.10)
Note
Only for internal use can the label in name also have the form (PROG)DOBJ, whereby PROG is the name of an ABAP program and DOBJ is the name of a global data object of this program. If the program PROG is loaded during execution of the statement ASSIGN in the same internal mode as the current program is loaded, the data object (PROG)DOBJ in this program is searched for and the field symbol points to this data object after successful assignment.
Example
Dynamic access to an attribute of an object (Dynamic Access) through a field symbol.
CLASS c1 DEFINITION.
PUBLIC SECTION.
    METHODS m1 IMPORTING oref TYPE REF TO object
                         attr TYPE string.
ENDCLASS.
CLASS c1 IMPLEMENTATION.
METHOD m1.
    FIELD-SYMBOLS <attr> TYPE ANY.
    ASSIGN oref->(attr) TO <attr>.

Field symbols or ?

Hi,
its possible form internal table like this:
tabname | row | columnName | columnValue
t005 | 1 | land1 | AD
t005 | 1 | landk | AND
t005 | 1 | lnplz | 00
t005 | 2 | land1 | AS
t005 | 2 | landk | ND
t005 | 2 | lnplz | 01
to create internal table "t005" in this structure:
row| land1 | landk | lnplz | ...
1 | AD | AND | 00
2 | AS | ND | 01
(use field-symbols, or dynamic attribute declarations...)
thanks, m

Try this...
Get the T005 data into internal table as first table...
tabname | row | columnName | columnValue
t005 | 1 | land1 | AD
t005 | 1 | landk | AND
t005 | 1 | lnplz | 00
t005 | 2 | land1 | AS
t005 | 2 | landk | ND
t005 | 2 | lnplz | 01
Now declare another internal table in the form...
row| land1 | landk | lnplz | ...
sort itab_t005 by tablename row.
now loop at itab_t005.
at new row.
clear itab_new.
endat.
if itab_t005-columename eq 'land1.
itab_new-land1 = itab_t005-columevalue.
endif.
the same for other two....
at end of row.
append itab_new.
endat.
endloop.
Hope this will solve ur porblem...

Accessing the attributes of a class using field symbols?

An option to pulll a variable into a user exit that otherwise would be out of reach is detailed [here|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/208811b0-00b2-2910-c5ac-dd2c7c50c8e8]
Can a similar approach involving field symbols or otherwise, be used to pull in the attributes of a class into the exit? For now, I'm trying to access the A_FRONTEND_INDEX attribute of the class CL_HRXSS_REM.
any ideas?
~Suresh

Hi,
Have you already tried (PROGRAM)(OBJECT)->A_FRONTEND_INDEX in your code? I prepared small testing scenario with two programs and it works.
REPORT zmv_test1.
FORM test.
FIELD-SYMBOLS: <fs> TYPE ANY.
ASSIGN '(ZMV_TEST2)zip->crc32_map' TO <fs>.
IF sy-subrc EQ 0.
<fs> = 'Test'.
ENDIF.
ENDFORM. "test
REPORT zmv_test2.
DATA: zip TYPE REF TO cl_abap_zip.
START-OF-SELECTION.
CREATE OBJECT zip.
PERFORM test IN PROGRAM zmv_test1.
Cheers,

Declaring Field Symbols in Public Section of class

Dear All,
I am working with class and hav declared some field symbols in one of the method.
Now I want to move these declaration in Public section of the class so that this field symbol declaration can be used by other methods of the class but I am not able to do the same.
Can anyone help me in finding as what I am doing wrong here.
Regards,
Lalit Kabra

What you are trying to do is define an attribute. I doubt you can use field symbol as a class attribute. Consider using a data object instead.
Data : dref type ref to data.
This can later be deferenced in the individual methods.
Hope this helps.
Here's an example for the same:
REPORT z_class_001                             .
*       CLASS lcl_class1 DEFINITION
CLASS lcl_class1 DEFINITION.

    DATA dref TYPE REF TO data.

              meth1 IMPORTING value TYPE i.
ENDCLASS.                    "lcl_class1 DEFINITION
*       CLASS lcl_class1 IMPLEMENTATION
CLASS lcl_class1 IMPLEMENTATION.

    CREATE DATA dref TYPE (i_type).

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.

Field symbol as import parameter in class method ???

Hi everyone,
is it possible to pass a field symbol as an import parameter to a method in a class? If yes, how do I define the data type of the import parameter? I'm trying to work with field symbols as the program doesn't know what kind of structure the program parameter p_srcdso has. Coding example would be something like this:
PARAMETERS: p_srcdso TYPE rsdodsobject DEFAULT '/BIC/AKVI0001'.
DATA: lr_srcpkg TYPE REF TO data.
FIELD-SYMBOLS: <fs_table> TYPE ANY TABLE.
CREATE DATA lr_srcpkg TYPE TABLE OF (p_srcdso).
ASSIGN lr_srcpkg->* TO <fs_table>.
SELECT *
FROM (p_srcdso)
INTO TABLE <fs_table>.
CALL METHOD cl_ref->create_somethign
EXPORTING
i_source_package = <fs_table>.
Thanks,
Alex

Halo Alexander,
You can use TYPE REF TO DATA( say the parameter name is i_data) as the importing parameter of the method create_somethign and inside the method you need to dereference it using data reference variable again.
data: dref type ref to data.
field-symbols: <fs_table> type table.
create data dref like i_data.
assign dref->* to <fs_table>.

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
                               exporting <fs_f_line> TYPE any
                                             <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>
                                                             <fs_f>      = <fs_final>.
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.

Hi
Maybe if you change this code below to field-symbol, it can work:
DATA: tl_header_csv TYPE STANDARD TABLE OF yol_header_arquivo,
      tl_csv_aux    TYPE textline_t                          .
DATA: wl_header_csv LIKE LINE OF tl_header_csv.
converter_csv_al11_itab( EXPORTING im_t_csv = tl_csv_aux
                         IMPORTING ex_w_sap = wl_header_csv
                         CHANGING ex_t_sap = tl_header_csv ).
METHOD converter_csv_al11_itab.
IM_T_CSV Importing Type TEXTLINE_T
EX_W_SAP Exporting Type ANY
EX_T_SAP Changing   Type STANDARD TABLE
