Field-symbols working

Hi Friends,
I am facing some problems with regards to handling of Field-symbols.
1. How can we do a move-corresponding like thing with a FIELD_SYMBOL. We have two Field-symbols and both are referring to lines in Internal tables. But there are some less fields in the Second Field-symbol(Work Area i.e. TYPE TABLE) than the First FIELD-SYMBOL(Work Area i.e. TYPE TABLE). I need to move the values in the Second using the First Field-symbol. How can we do this.
I cannot do an Assign component as I cannot provide the Fieldname in the Second Field-symbol(Work Area).
2. the Second problem is how can we clear any particular Field in the field-symbol(TYPE TABLE).
Thanks and Regards,
Arunava

Hello Arunava,
When you declare your field symbols, declare it like this:
FIELD-SYMBOLS: <fs1> like line of ITAB1,
               <fs2> like line of ITAB2.
Then for
1. After you have assigned the record to corresponding field symbols, you can do this statement
    MOVE-CORRESPONDING <fs1> to <fs2>
2. You can do like this to clear individual fields
   LOOP AT ITAB1 assigning <fs1>.
      CLEAR <fs1>-field1.
      MODIFY ITAB1.
   ENDLOOP.

Read dynamic field symbol Work Area before append to dynamic table

Hi experts:
I have a dynamic work area but before doing an append to the dynamic table, I need to do some validation on some fields of the work area in order to decide to append it or not, but I don't know how...
More or less this is the example
loop at so_kschl.
    field = so_kschl-low.
    if <t_dyntable>-field = 0. "if the value of this field in dinamic table is 0.
don't append
    else.
       APPEND <fs_dyntable> TO <t_dyntable>.
    endif.
endloop.
Thank you very much for your help.

Check this example, you read the component of the dynamic work area and assign it to a field-symbols. In this case, I validate that the entry is always 'a'.
DATA: i_lvc TYPE lvc_t_fcat WITH HEADER LINE,
      i_table TYPE REF TO data,
      l_style TYPE lvc_fname,
      l_warea TYPE REF TO data,
      l_name(7) VALUE 'VARCHAR'..
FIELD-SYMBOLS: <fs> TYPE table,
              <fs2> TYPE ANY,
              <fs3> TYPE ANY.
PARAMETERS p_char TYPE c LOWER CASE.
START-OF-SELECTION.
i_lvc-fieldname = 'Varchar'.
i_lvc-inttype = 'C'.
i_lvc-intlen = 1.
APPEND i_lvc.
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
it_fieldcatalog = i_lvc[]
IMPORTING

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.

Field symbols not working in data transfer VOFM routine

Hi,
I have been trying to set a value using field symbols, however for some reasons its not working. I am using a field symbol in a data transfer routine and the value which I am trying to set is a standard field outside the VOFM routine code.
I am trying to set a field gla_subrc which is actually a changing parameter.
The actual paramter is gn_subrc of type sy-subrc and within the form the name is gla_subrc. I need to set this changing parameter gla_subrc using the data transfer routine.
Is there a specific rule that field symbols dont work for changing paramters within subroutine or is there a specific syntax.
The syntax I am using is
ASSIGN ('(SAPLV50S)gla_subrc') to <fs>.
I also used the local program name instead of main program but still that does not work. Tried using the actual parameter as well.
Can someone please help me in this.
Thanks & Regards,
Naresh.

I need to stop outbound delivery creation against STO using vl10b transaction. The only way to stop creation is using data transfer delivery VOFM routine.
If i give an error message MESSAGE E001, this will give a hard error which is not acceptable. To avoid this, i use a perform message statment with message id and certain parameters which can displayed in a log.
However to make sure this message is displayed in log, I am clearing a work area having specific data needed for delivery creation.
Because of this clear, my error message gets captured in log but along with this another fake message is displayed in log which caused by the clear message.
The user gets confused as he now sees 2 messages, 1 which is correct and other 1 which is fake and that confuses him.
Data transfer routine is not the best place to give messages in log but we have very few options. The only way the system can give 1 message is if i set gla_subrc to 1. This is a variable which will help the system understand that the delivery should not be created as there is something wrong because the value is 1. Hence it will stop the creation and instead display whatever message i had passed to the log.
I need to somehow set this variable to 1 based on lot of analysis that has been done in the past.
Please let me know if there is any way by which we can fix this.
Thanks & Regards,
Naresh.

Difference between Field symbols and work area for Internal tables

Hi,
In ECC versions we all know that we need to declare the internal tables without headerline, and for handling the internal tables we need to use exclusive work areas.
Currently i have an issue that we have been asked to use field symbols instead of work areas...can any one help me how to use the field symbols and also let me know how it will improve the performance of the program..
Thanks and Regards,
Kathir

Hi
DATA: WA TYPE ITAB.
LOOP AT ITAB INTO WA.
IF WA-FIELD = .....
ENDIF.
ENDLOOP.[(code]
FIELD-SYMBOLS <WA> TYPE ANY.
LOOP AT ITAB ASSIGNING <WA>.
ENDLOOP.
Now the problem is you can't know the name of the fields of the table at runtime, so you can't write:
IF <WA>-FIELD = .....
ENDIF.
Anyway you can create a field-symbols strcturated like the table:
[code]FIELD-SYMBOLS <WA> TYPE ITAB.
LOOP AT ITAB ASSIGNING <WA>.
IF <WA>-FIELD = .....
ENDIF.
ENDLOOP.
I don't know which are the differences for the performance between to use a field-symbol and to use a structure as work-area.
The differnce between the field-symbols and work-area is the field-symbol is assigned directly to the record, so u don't need to do a MODIFY statament to change something:
LOOP AT ITAB INTO WA.
WA-FIELD =
MODIFY ITAB FROM WA.
ENDLOOP.
LOOP AT ITAB ASSIGNING <WA>.
<WA>-FIELD =
ENDLOOP.
These two pieces of abap code do the same action, so probably the field-symbol improve the performance because it do an access directly to the record without to use an external structure as workarea.

Declaring Field Symbols in a work area

Hi all!
I'm triying to learn the use of FieldSymbols, and I wrote in my code this:
REPORT zpractica01.
Types
TYPES: BEGIN OF ty_tabla,
        name(25)    TYPE c,
        address(60) TYPE c,
        monto(3)     TYPE p decimals 2,
        END OF ty_tabla.
Internal Table
DATA: t_tabla TYPE STANDARD TABLE OF ty_tabla.
*Work Area
DATA: vl_variable TYPE c LENGTH 512.
Field Symbols
FIELD-SYMBOLS <linea> STRUCTURE st_tabla DEFAULT vl_variable.
If I try to activate the code I see this error:
In the Unicode context, the structure <LINEA> typed using STRUCTURE can only contain character-type components (type C,N,D,T).
I can see that the problem begins when I use a type P inside the structure, but I need to have a type P, so I would like to know how can i use it.
Could you please teach me how I should declare my field symbols in order to use as an structure with a type P field within a loop at - endloop?
I'll really appreciate your help.
Best regards!

Hello Gaby,
You are getting the error because the structure st_tabla & variable vl_variable are not mutually convertible in a Unicode environment.
Just change the definition of vl_variable & you code will activate.
REPORT zpractica01.

TYPES: BEGIN OF ty_tabla,

Performance Field Symbols Vs Work Area

Hi,
I want to some operations (Validations and Calculations) form each entry of internal table.
Which is better way to access the data in internal table either using field symbol or using work area?
I heard that using filed symbols is performance issue. May I know in which cases we should not use field symbols?
Regards,
Kumar

I do not think, the runtime creates a pointer to each line of the itab.
The developer creates ONE fieldsymbol ( for a loop for example ) --> a pointer, which is iteratively assigned, pointing to only one line at one time.
With the usage itself it seems to offer a benefit, which isn't really one, If You only read data.
People might say, You can omit a clear, if working with fieldsymbols.
But You have to add a check for sy-subrc, or You will suffer from a dump, which usually never happens, if working with work areas the same way, like fieldsymbols.
The real benefit only comes into play, if You want to modify the data in the internal table, because You are already acting on the line of the table (pointer to record n ), what allows You, to omit any modify to transfer changed values back to the internal table.
In terms of performance I must see it technically and I hope, someone can confirm/reject my statement, so that I (if I was wrong) could keep that in mind.
A fieldsymbol (lets talk about them in technical way, as a pointer) is in fact a variable, which holds an address of another variable( which itself also can hold an address and so on).
Pointers are either 4 byte or 8 byte. So, it does not matter, how much columns Your internal table has, technically the fieldsymbol is either 4 byte big or 8 byte big. And exactly this amount is used in the ram of the application server.
In fact pointers even do not have a type, as usual pointers are always integer.
A workarea is a linear, continous allocation of memory space, exacly matching the data-structure, which is used for declaration. So it is obvious, that this workarea uses much more memory of the ram, as long their elements exceed 4 / 8 bytes.
Still then it is not more performant, because changed data of a workarea has to be transferred to the internal table, (mostly, if one wants to modify), but with field-symbols this step is removed.
So in fact there are two technical reasons for using field-symbols.
One is, You save memory-space and the second is, You save the transferring.
In an even deeper way, one can say, that , by design, a cpu with its address bus is just intended to understand addresses best ( directly after 0 and 1 and hex ).

Field symbol to work area

Hello experts,
                   I am getting a problem while working with field symbols. I have some data field symbol in the form of structure. The field symbols have the type 'TABLE' so the data fills in runtime, so the structure also changes runtime. We need to get some fields out form them in the work area.
    How can I do that? Is there any code you can give me so that I can use that.
Please help.
Thanks,
Ganesh

Hello,
Use the Assign statement.
Try like this.
LOOP AT <FS_1> ASSIGNING <FS_2>.
    ASSIGN COMPONENT 'POSIDFROM'
    OF STRUCTURE <FS_2> TO <FS_5>.
    LV_POSID = <FS_5>.
endloop.

How to fill Dynamic work area or field symbol?

HI All,
I have created dynamic work area(field symbol) by using following code. Now I want to fill the work area with values which are there in other internal table.
* Create dynamic internal table/structure
call method cl_alv_table_create=>create_dynamic_table
    exporting
      it_fieldcatalog = it_fieldcat
    importing
      ep_table        = dyn_table.
assign dyn_table->* to <fs_table>.
* Create dynamic work area and assign to Field Symbol
create data dyn_line like line of <fs_table>.
assign dyn_line->* to <fs_wa>.
My <FS_WA> contains:
ROW1
ROW2
ROW3
ROW4 as fields in it without having any data.
I have other internal table.. where I have FIELDS and Data like following:
FIELD1 FIELD2   FIELD3
ID1 ROW1 A1
ID1 ROW2 A2
ID1 ROW3 A3
ID1 ROW4 A4
ID2 ROW1 B1
ID2 ROW2 B2
ID2 ROW3 B3
ID3 ROW1 C4
Important thing that I have to share with you is... Source table of my Internal table and Source structure to create my dynamic table are same.
This dynamic table has fields... with "FIELD2" values.

Dynamic Work Area and field symbol

Hi All,
I'm have a big internal table like this
data: begin of data occurs 0,
Field01,
Field02,
Field03,
*bucket 1
Field04,
Field05,
Field06,
*bucket 2
Field04,
Field05,
Field06,
*bucket 3
Field04,
Field05,
Field06,
Field 1, 2 3 will be the same for pernr, first last name.
Field 4, 5, 6 are the same format but different numbers (or values ) in different buckets.
Each bucket can be shown (or not) based on the condition of a person, for example if that person live in 2 states, it will show 2 bucket with 2 address info inside each.
I will run this under get pernr to sort out each person who have many address or not.
Can I use dynamic work area and field symbol here? if I can, how?
Really appreciate your help with points...

You can use the ASSIGN COMPONENT ... and than APPEND the work area to the table.
Check out this sample program:
REPORT ZTEST_NP.
DATA: BEGIN OF ITAB OCCURS 0,
      F1    TYPE I,
      F2    TYPE I,
      F3    TYPE I,
      END   OF ITAB.
DATA: WA_ITAB LIKE ITAB.
DATA: L_CNT TYPE I.
FIELD-SYMBOLS: <F_FLD> TYPE ANY.
DO 10 TIMES.    " I want 10 reocrds
CLEAR L_CNT.
DO 3 TIMES.   " I have 3 fields
    L_CNT = L_CNT + 1.
    ASSIGN COMPONENT L_CNT OF STRUCTURE WA_ITAB TO <F_FLD>.
    <F_FLD> = L_CNT.
ENDDO.
APPEND WA_ITAB TO ITAB.
CLEAR ITAB.
ENDDO.
LOOP AT ITAB INTO WA_ITAB.
WRITE: / WA_ITAB-F1,
           WA_ITAB-F2,
           WA_ITAB-F3.

How to assign values to a work area which is a Field Symbol?

Hello Experts!
I really need your help! this is the problem:
I need to assign values to fields into a work area which is a field symbol. The values come from a flat file I uploaded and as I can't know the length I had to build the structure dynamically ( That's why I'm using FS). Each field comes from the file separated by ';', I tried using the SPLIT sentence:
"SPLIT text AT ';' INTO TABLE <dyn_table>." but the values are assigned vertically into the same field instead of horizontally into each field of the table(field-symbol table).
I know the name of the field dynamically
(a TEXT + number) and I know I can't do this
<dyn_wa>-TEXT1 or field_name = 'TEXT1' <dyn_wa>-(field_name).... ohhh I'm blocked, I don't seem to find the answer, please help!
Thanks in advance!!
Frinee

Now that you have a table with the values, you can move them to the work area.
data: begin of wa,
      fld1(20) type c,
      fld2(20) type c,
      fld3(20) type c,
*     and so on
      end of wa.
data: istr type table of string with header line.
field-symbols: <fs>.
split text at ';' into table istr.
loop at istr.
assign component sy-tabix of structure wa to <fs>.
if sy-subrc <> 0.
exit.
endif.
<fs> = istr.
endloop.
write:/ wa-fld1, wa-fld2, wa-fld3.
Now, WA has the values in a horizontal fashion.

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

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.

Right way to declare field symbols

i am new to field symbols, pls help
i want to know which is the right way of declaration ?
types: begin of typ_tab,
           vbeln type vbap-vbeln,
           posnr type vbap-posnr,
           matnr type vbap-matnr,
          end of typ_tab.
data: itab type standard table of typ_tab,
          wa type typ_tab.
field-symbols: <f_t> type standard table,
                       <f_w> type any,                or      <f_w> like line of typ_tab, ??
                        <f_s> type any.
select vbeln posnr ....... into itab......
assign itab to <f_t>.
assign wa to <f_w>.
loop at <f_t> assigning <f_w>.
assign component 'vbeln' of structure <f_w> to <f_s>.
write : / <f_s>.
endloop.
OR
loop at itab assigning <f_w>.
write: / <f_w>-vbeln.
endloop.
r these 2 statements correctt ? if so then which one to use, pls show with an example. wats the diff btwn above 2 types of looping statements ?   how to use read statement on this ?

Hello Saurajit,
Both the way are correct. And it depends on the requirement, which one to use.
<f_w> TYPE ty_tab - is TYPED field symbol - if you know TYPE before runtime you can use this. It will just work like a static work area.
<f_w> TYPE any - is not TYPED and structure of this field symbol is defined during runtime using ASSIGN statement. And fields of the structure is read by ASSIGN COMPONENT <<field name>> statement.

Field-Symbols: How to retrieve data into an internal table from FS

Hello All,
I am working on field symbols.I have declared the field symbols as shown.
FIELD-SYMBOLS: <gt_pos_data> TYPE table,
                           <wa_pos_data> like <gt_pos_data>.
Data: Begin of itab occurs 0,
           field1(5) type c,
           field2(10)_type c,
         end of itab.
The FS <gt_pos_data> has 100 fields but I need to move only two fields from this FS to my internal table itab.I am doing the following.
loop at <gt_pos_data> assigning <wa_pos_data>.
itab-field1 = <wa_pos_data>-field1.
itab-field2 = <wa_pos_data>-field2.
append itab.
clear itab.
endloop.
But it is giving me an error saying "<wa_pos_data> is a table without header line and therefore has no componet FIELD1".How to achieve this requirement?
Thanks in advance
Sandeep

<wa_pos_data> should be defined LIKE LINE OF <gt_pos_data>, but it will still have no structure, so you need to assign a field symbol to the component as well.
FIELD-SYMBOLS: <gt_pos_data> TYPE table,
                           <wa_pos_data> like LINE OF <gt_pos_data>,
                           <field> type any.
Data: Begin of itab occurs 0,
field1(5) type c,
field2(10)_type c,
end of itab.
loop at <gt_pos_data> assigning <wa_pos_data>.
assign componet 'FIELD1' of structure <wa_pos_data> to <field>.
if sy-subrc = 0.
itab-field1 = <field>.
endif.
assign componet 'FIELD2' of structure <wa_pos_data> to <field>.
if sy-subrc = 0.
itab-field2 = <field>.
endif.
append itab.
clear itab.
endloop.

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

Hi,
this error occurs when you try to address a field-symbol before it has been assigned to a field or
the assignment has failed.
Use following code to remove this dump
Assign <mara-matnr> to <fs>.
if sy-subrc <> 0.
Error Message.
Endif.
Hope it helps,
Raj
