Wacth points on Field symbols

Hi Experts,
Is it possible to create a watch point on Field symbols?
If so please explain the procedure.
Ex:
LOOP AT p_c_t_data ASSIGNING <fs_c_t_data>.
ENDLOOP.
Iam trying to create watchpoint on KUNNR field of the internal table i.e <fs_c_t_data>-KUNNR, it is
showing wacth point created but when i press F8 it is not stopping at the specified value ( Value is there
in internal table).
Could you please help anyone on this.
Thanks in Advance
Shaik

Hi Shaik,
It is not possible to create watch point for field-symbols.Technically field symbol wont allocate any memory before assign in other words field symbols cannot be recognised unless the assign statement is triggered.
Thanks and Regards,
Srini...

How to access the value of a field of a field symbol.

Hello All,
i need to access the value of a field in a field symbol. But when i am trying to get the value like <FS>-POSNR, it's showing that that the <FS> has no structure.
In my program, the field itself that i need to check should be dynamic. ie i'll get the field in a variable and i need to find the value of that field.
Am pasting my code below, please tell me what needs to be done.
here in my sample code i am moving the entry of the <FS> into a work area structure. But in my actual program, i gets the structure as a parameter. So is there any way i can declare a work area dynamically...

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.
Goto SE24 tcode and see the std global classes like

FIELD-SYMBOLS as parameter subroutine that point to table

Hi everyone,i have question. We often send table through subroutine using keyword TABLE.
FORM f_xxx TABLES pt_xxx
Now my question is possible send this internal table through field symbols? If so, how to do this?
1. FORM f_xxx USING <fs_xxx> STRUCTURE ty_xxx or
2. FORM f_xxx CHANGING <fs_xxx> STRUCTURE .... or
3. FORM f_yyy TABLES <fs_yyy>
Thank you.

Field symbols and READ TABLE with system code 4

Hi,
I have a hashed table and I am using field symbols to point to it to retrieve the field content. I then use it in the READ TABLE statement in the following way:
Loop at x_data assign <fs>.
ASSIGN COMPONENT 'xxx' OF STRUCTURE <fs> TO <c1>.
ASSIGN COMPONENT 'xxx' OF STRUCTURE <fs> TO <c2>.
READ TABLE ZZZZ assign <fs> with table key a1 = <c1>
a2 = <c2>.
If sy-subrc = 0.
endif.
I ran the debugger and I keep getting a 4. I am not able to get the value from a1 and a2 to see what it is and why it is causing a 4 sy-subrc. I know the value from the hashed table and the values c1 and c2 are the same, so the sy-subrc should be 0.
How would I read a hashed table using field symbols? I know that usig a standard table, I have to sort the table on the key fields() before I actually can do the READ TABLE using the binary search.
Please advise. Thanks
RT

Hai Rob
Go through the following Code
Field-Symbols are place holders for existing fields.
A Field-Symbol does not physically reserve space for a field but points to a field, which is not known until run time of the program.
Field-Symbols are like Pointers in Programming language C .
Syntax check is not effective.
Syntax :
Data : v1(4) value abcd.
Field-symbols <fs>.
Assign v1 to <fs>.
Write:/ <fs>.
DATA: BEGIN OF LINE,
COL1 TYPE I,
COL2 TYPE I,
END OF LINE.
DATA ITAB LIKE SORTED TABLE OF LINE WITH UNIQUE KEY COL1.
FIELD-SYMBOLS <FS> LIKE LINE OF ITAB.
DO 4 TIMES.
LINE-COL1 = SY-INDEX.
LINE-COL2 = SY-INDEX ** 2.
APPEND LINE TO ITAB.
ENDDO.
READ TABLE ITAB WITH TABLE KEY COL1 = 2 ASSIGNING <FS>.
<FS>-COL2 = 100.
READ TABLE ITAB WITH TABLE KEY COL1 = 3 ASSIGNING <FS>.
DELETE ITAB INDEX 3.
IF <FS> IS ASSIGNED.
WRITE '<FS> is assigned!'.
ENDIF.
LOOP AT ITAB ASSIGNING <FS>.
WRITE: / <FS>-COL1, <FS>-COL2.
ENDLOOP.
The output is:
1 1
2 100
4 16

Hi,
The problem seems to be in your ALV grid display.
The reason must be your field catalog.
Just check your fieldcatalog.
The value in the fieldname field of the fieldcatalog should be same as the fieldname in your internal table and should be in capital letters.
Probably you must have mistyped some field.
Kinldy check.

Field-symbols v/s Object references in OO-ABAP

Hi,
can anyone please tell me what is the difference between using field-symbols and object references in OO ABAP? Is there a specific need for field-symbols now that we have references?
Thanks.
Shakul.

Hi ,
Please note that both Field symbols & Object References are different .
You can use Field symbols during the following situations
1) When you want to modify the value of internal table, the field symbol would be useful since you do not have to use any Modify statement as in case of work area. The Field symbol works as a pointer and any changes to the field symbol will directly affect the value of the internal table
2) Make sure that you do not reassign the field symbol within a Loop iteration
3) Field symbols are useful when you work with dynamic internal tables ( tables whose structure is determined during run time)
4) After Read an internal table ( Read itab...) into a Field symbol, make sure you do a Sy-subrc check or check if the field symbol is assigned.IF not this will give you a run time error
You can use Object References while creating an object to a class. They are instances of a class.
Thanks,

How to use different field symbols to append data in a loop

Hi experts!
I have to loop over a itab and I want to save different into one table.
See my code below:

ENDIF.
ENDLOOP.
My goal should be to fill the graphic with 4 Lines:
1 is boarderline.
2-3 are the lines with the looped values in "ztab"
Do I have to use references to write the values in into different rows of internal table "grfk_values"????
With this code I want to fill the itab which I need for the GFW_PRES_SHOW function.
The table I have to commit has the following structure:
-rowtxt
-val1
-val2
-val31
EDIT:
My current output are 2 lines the first has value 0 for each point and the second shows the correct values... The boarder which always should have value 10 is completly not shown.

RUn time error while saving po    Field symbol has not yet been assigned.

Hi Experts,
I am getting abap dump while saving PO in ME21N plz seee the below dump plzzzzzzzzzzzzzzzzzzzzz help me
Runtime Errors         GETWA_NOT_ASSIGNED
Date and Time          19.06.2009 11:24:46
Short dump has not been completely stored (too big)
Short text
     Field symbol has not yet been assigned.
What happened?
     Error in the ABAP Application Program
     The current ABAP program "SAPLKKBL" had to be terminated because it has
     come across a statement that unfortunately cannot be executed.
What can you do?
     Note down which actions and inputs caused the error.
     To process the problem further, contact you SAP system
     administrator.
     Using Transaction ST22 for ABAP Dump Analysis, you can look
     at and manage termination messages, and you can also
     keep them for a long time.
Error analysis
     You attempted to access an unassigned field symbol
     (data segment 106).
     This error may occur if
     - You address a typed field symbol before it has been set with
       ASSIGN
     - You address a field symbol that pointed to the line of an
       internal table that was deleted
    - You address a field symbol that was previously reset using
      UNASSIGN or that pointed to a local field that no
      longer exists
    - You address a global function interface, although the
      respective function module is not active - that is, is
      not in the list of active calls. The list of active calls
      can be taken from this short dump.
How to correct the error
    If the error occures in a non-modified SAP program, you may be able to
    find an interim solution in an SAP Note.
    If you have access to SAP Notes, carry out a search with the following
    keywords:
    "GETWA_NOT_ASSIGNED" " "
    "SAPLKKBL" or "LKKBLF99"
    "GEN_FIELD_OUT2"
    If you cannot solve the problem yourself and want to send an error
    notification to SAP, include the following information:
    1. The description of the current problem (short dump)
       To save the description, choose "System->List->Save->Local File
    (Unconverted)".
    2. Corresponding system log
       Display the system log by calling transaction SM21.
       Restrict the time interval to 10 minutes before and five minutes
    after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
   In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.

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.

Assigning value to Field - Symbol ( which is type of internal table field )

Hi All,
I am facing problem to assign the value to a field symbol. My requirement is creating a dynamic internal table and populate values into that internal table, so that i can display the values .
I am having a structure with fields like status , Plant1 name , Plant2 name.....Plant n .
So i declared an internal table it_tab with this structure.
I am having one more table which having number of records for Plant1 ,Plant 2 ,....Plant n based on some condition.
I need to count the number of records for Plant1 and i need to put in the internal table it_tab.
For this i created field-symbol .
Here, t_deployment table will have the plants 1,2,3...and
     t_devobject will have some records for these plants.
LOOP AT T_DEPLOYMENT.
clear w_count.
LOOP AT T_DEVOBJECT WHERE ZDEPLOYMENT = T_DEPLOYMENT-DOMVALUE_L AND
                          ZADSTATUS = '10'.
w_count = w_count + 1.
ENDLOOP.
concatenate 'it_tab-' t_deployment-domvalue_l into var_bet_name.
assign var_bet_name to <bet_var_name>.
now my internal table field i.e. it_tab-plant1 came into <bet_var_name> . But i want to assign a value for it.
at last what i need is it_tab-plant1 = w_count.
whaterver the w_count has value that needs to assign to it_tab-plant1. But i don't want to assign directly it it_tab-plant1. I want to assign dynamically. Because tommorrow some more plants added to t_deployments , i don't want to make changes to my program. It should take care....w/o changing the program.
I tried the following statement.
(<bet_var_name>) = w_count. But its not working.
Please let me know how i can get this.
Thanks in Advance.

Hi pavan,
As ur requirement is creating a dynamic internal table,
try the following way,
remember the fieldcat should be of type LVC not SLIS.
BUILD LT_LVCFIELDCAT in a way that, the value from the internal table becomes the fieldname
ex:-
loop at it_models INTO WA_MODELS.
    LS_LVCFIELDCAT-FIELDNAME = WA_models-MODEL.
    LS_LVCFIELDCAT-SELTEXT = WA_models-MODEL.
append ls_lvcfieldcat to lt_lvcfieldcat.
endloop.
DATA: DREF TYPE REF TO DATA,WA_REF TYPE REF TO DATA.
FIELD-SYMBOLS: <TEMP_TAB> TYPE TABLE, <TEMP_WA> TYPE ANY.
CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE
    EXPORTING
      IT_FIELDCATALOG = LT_LVCFIELDCAT
    IMPORTING
      EP_TABLE        = DREF.
ASSIGN dref->* TO <TEMP_TAB>.
now basing on the fieldcatalog <temp_tab> is build.
NOW FILL <TEMP_TAB>.
WHILE FILLING, ASSIGN COMPONENT IDX/NAME.....
this statement will be very usefull.
i hope this will be help full.
pls reward the points if it helps u.

Dynnamic Field Symbol returning short dump ASSIGN_TYPE_CONFLICT

Hi everyone,
I have a RFC FM and make a dynamic access via SYMBOL FIELD, declared as ANY TABLE. The problem is that sometimes I can get a structure instead of a table and then the error occurs. How do I handle this error if the check IS ASSIGN not work? How do I capture and return an error message?
I tryed this:
FIELD-SYMBOLS: <fs_tabela> TYPE ANY TABLE.
     TRY.
                 ASSIGN (st_b2b_text-tabname) TO <fs_tabela>.   <<<<----
DUMP HERE!
              CATCH cx_root INTO v_erro.
                v_text = v_erro->get_text( ).
                MOVE v_text TO st_return-message.
                APPEND st_return TO t_return.
                PERFORM f_return_error_pi USING event.
      ENDTRY.
            IF <fs_tabela> IS ASSIGNED.
              CONCATENATE 'S' st_b2b_text-tabname INTO vl_wkarea.
              CONDENSE vl_wkarea NO-GAPS.
              ASSIGN (vl_wkarea) TO <fs_wkarea>.
              IF <fs_wkarea> IS ASSIGNED.
                LOOP AT <fs_tabela> ASSIGNING <fs_wkarea>.
                  ASSIGN COMPONENT c_posnr
                  OF STRUCTURE <fs_wkarea> TO <fs_posnr>.
Does anyone have any tips?
