Hi ,
Please find below code when I tried in version 4.6 code works correctly . but in 6.0 it gives short dump..
Here.
FIELD-SYMBOLS : <fs_table> TYPE ANY TABLE.
FIELD-SYMBOLS : <fs_work_area> TYPE yatsdzz00.
ASSIGN pr_data_changed->mp_mod_rows->* TO <fs_table>.
LOOP AT <fs_table> ASSIGNING <fs_work_area>. (In there system gives short dump)
Thanks in advance.Hai,
Use CASTING or CASTING TYPE (mytype) after LOOP AT <fs_table> ASSIGNING <fs_work_area>.
ie:
FIELD-SYMBOLS : <fs_table> TYPE ANY TABLE.
FIELD-SYMBOLS : <fs_work_area> TYPE yatsdzz00.
ASSIGN pr_data_changed->mp_mod_rows->* TO <fs_table>.
LOOP AT <fs_table> ASSIGNING <fs_work_area> <b>CASTING or CASTING TYPE (mytype).</b>

Deal All,
i am using field symbol here,while trying to assign the character value into field smybol.
It is generating the error.cannot be converted into number ..so wht should be the type of the field symbol.
field-symbol : <RATING> TYPE ANY.
CONCATENATE 'wa_final1-f' V_COUNT INTO V_FIELD.
CONDENSE V_FIELD.
ASSIGN (V_FIELD) TO <RATING>.
WRITE WA_FINAL-RATING1 TO V_PAK .
<RATING> = V_PAK. "ERROR GENERATING HERE WHILE ASSIGNING VALUE OF V_PAK TO <RATING>
VALUE OF V_PAK = 'DME' ( I.E CHARACTER FIELD).
thanks in advance..field-symbol : <RATING> TYPE ANY.
CONCATENATE 'wa_final1-f' V_COUNT INTO V_FIELD.
CONDENSE V_FIELD.
ASSIGN (V_FIELD) TO <RATING>.
WRITE WA_FINAL-RATING1 TO V_PAK .
UNASSIGN <RATING>.
ASSIGN V_PAK TO <RATING>.

Read Data from the dynamic Field Symbol with key ?
Dear All,
I've 2 dynamic internal tables in the form of field symbols.
Now,I want to loop the item field symbol, read the header field symbol content and then move the corresponding into a final field symbol.
How to read the field symbol with key ?
When I'm trying to give the key clause in the paranthesis it's giving a syntax error.
Any clues ?
FYI .....
* Get the Dynamic Field and Value for the Date/Year and convert it into Year value
LOOP AT <fs_t_son> ASSIGNING <wa_son>.
ASSIGN COMPONENT gwa_znrows_def-fieldname OF STRUCTURE <wa_son> TO <fs_year>.
IF sy-subrc = 0.
CLEAR gv_string.
MOVE <fs_year> TO gv_string.
CLEAR gv_year.
gv_year = gv_string.
<fs_year> = gv_year.
ELSE.
* When the Date/year Field is not in the Table then -->
* Get the Dynamic Field and Value
ASSIGN COMPONENT gwa_znrows_def-kfldname OF STRUCTURE <wa_rson> TO <fs_value>.
* Populate field for Dynamic Where condition
CLEAR gv_value.
CONCATENATE '''' <fs_value> '''' INTO gv_value.
CONCATENATE gwa_znrows_def-kfldname '=' gv_value INTO gt_where SEPARATED BY space.
APPEND gt_where.
CLEAR gt_where.
READ TABLE <fs_t_rson> ASSIGNING <wa_rson> ( gt_where ). "Key clause
ENDIF. " if sy-subrc = 0. "Assign
ENDLOOP.

Deepu.KTYPES: BEGIN OF line,

FIELD-SYMBOLS <fs> TYPE ANY TABLE.
ASSIGN itab TO <fs>.
READ TABLE <fs> WITH TABLE KEY (key) = 'X' INTO wa.
The internal table itab is assigned to the generic field symbol <fs>, after which it is possible to address the table key of the field symbol dynamically. However, the static address
READ TABLE <fs> WITH TABLE KEY col1 = 'X' INTO wa.
is not possible syntactically, since the field symbol does not adopt the key of table itab until runtime. In the program, the type specification ANY TABLE only indicates that <fs> is a table. If the type had been ANY (or no type had been specified at all), even the specific internal table statement READ TABLE <fs> would not have been possible from a syntax point of view. -
Problem after assigning field-symbol in read statement...
Hello Experts,
I want to use a universal field-symbol in reading my internal tables so
I can avoid declaring multiple work areas. Here is my code:
FIELD-SYMBOLS: <fs_any> type any.
READ TABLE lt_orderadm_h INDEX 1 ASSIGNING <fs_any>.
Now when I try to insert this code:
IF NOT <fs_any>-object_id IS INITIAL.
ENDIF.
It says that <fs_any> has no structure and therefore no component called object_id.
I think that I need to use assign component for this but I don't know the code.
Thank you guys and take care!Hi

Problem in assigning field symbol to a nested internal table
Hi All,
I have searched the forum but could not find a solution to this problem. I have a requirement where I need to define an internal table within an internal table, so I have used pointer within the outer internal table(itab2) which point to the inner table. However, I am facing problem while assigning the pointer.
data: begin of struct1 occurs 0,
fld3(10) type C,
end of struct1.
data: begin of itab2 occurs 0,
fld1(10) type C,
fld2(10) type C,
p_inner like ref to struct1,
end of itab2.
field-symbols <inner_table> type any.
I want to assign "itab2->p_inner->* " to "<inner_table>".
However, the following statement is Not working:
assign itab2->p_inner->* to <inner_table>.
I want to fill the values within fields fld1, fld2 and fld3 and append it in itab2.
The final table should be like:
ITAB2:
fld1 fld2 fld3
aa bb cc
dd
ee
11 22 33
44
55
I have tried many other ways too but could not suceed, please help.
Thanks,
Vishal.Thanks Matt,
But how do I append the values within this internal table ??
When I am using the following code:
ls_wa-fld3 = 'A'.
ls_wa-t_in-fld1 = 'B'.
ls_wa-t_in-fld2 = 'C'.
ls_wa-t_in-fld1 = 'D'.
ls_wa-t_in-fld2 = 'E'.
append ls_wa to lt_tab.
Its giving an error that:
The data object "LS_WA" does not have a component called "T_IN-FLD1".
I wanted the values to be appended in the following way in lt_tab:
fld3 fld1 fld2
A B C
D E

Problem with field symbols in ecc 6.0
i have the following code written in 4.6 version now i am executing the old report in 6.0 but i am facing with some unicode error.
FIELD-SYMBOLS:

i have the following error in ecc 6.0
structure type '<line_of_bs_table> >+col_bst' does not start with a charecter type field in unicode programs in such cases
offset/ length declarations are not allowed.
can any one tell how can a field symbol structure is changed to charecter type.Hi elinuk,
you have already posted this thread in the ABAP general forum under problem in field symbols in ecc6.0 and I think that this forum is more related to this issue than the DMS forum. So please close this thread and investigate this issue further in the ABAP general forum.

Dynamically table read / write with field symbols
Hi,
I like to read dynamically from a table via field symbols. The reading part is working.
But now I like to do some changes on the entry and then write it to another table with a similar structure.
I use SAP 4.6c
There I have two problems:
1. At the statement I get a dump:
<l_sysid> = sy-sysid.
--> Field symbol has not yet been assigned.
I think that the problem is somewhere around
assign <table_to> to <wa_to>.
2. the data change inside the loop. There I like to add the sysid to the target-wa and then copy the source-wa it to the new target-wa to append it to the target table.
But this does not work. What kind of code do I need? The "move-correspondig" is not correct.
--> see code around
loop at <table_from> assigning <wa_from>.
Below you can find my code. The problem is within the last loop-statement.

TomHi,
Answers below.
1) For this...you assigning an internal table to a work area...
assign <table_to> to <wa_to>.
This should solve the problem..
* Create the target work area..
DATA: new_line TYPE REF TO data.
CREATE DATA new_line LIKE LINE OF <table_to>.
ASSIGN new_line->* TO <wa_to>.
Now the target work area is created..
2) For the second one...
************New code

Problem with populating internal with field-symbol
hi all,
I have following structure of internal table .
internal Table 1(int1) : source,source_field, and other fields.
internal Table 2 (int2): x1,x2,x3,x4,x5,x6 .
Read table 1 assigning <gs_t1> with....
assign ( <gs_t1>-source_field ) to <ld_char> .
case <gs_t1>-source.
when 'int1'.
Read int1 assgining <gs_int1> .
ASSIGN COMPONENT <ld_char> OF STRUCTURE <gs_int1>
TO <fs_char>.
wa_output-x1 = <fs_char>.
simillarly,
ASSIGN COMPONENT <ld_char> OF STRUCTURE <gs_int1>
TO <fs_char>.
wa_output-x2 = <fs_char>.
The source_field of int1 contains any value either it can be x2,x3,x4 .
Now the problem is how my work wa_output should know that <fs_char> contains value of field x1 .
I mean to say how we willl determine that value to be passed is to wa_output-x1 or wa_output-x2 as <ld_char> is just a pointer we cannot determine anything .
so how should i make my workarea . It can be made as a fields-symbol but how to that .
As it is having a strucutre of like :
componenet component_type
CONTROLLER PRXCTRLTAB<-this is also a line type having value two fields
x1 char5
x2 char5
Plz help...Hi all,
i have to pass all field values after obtaining them to a workarea wa_output .
data : wa_output type xyz.
READ TABLE ist_smp_tst ASSIGNING <gs_smp_tst>
WITH KEY iden_no =
<gs_smp_tst_dtl>-iden_no
BINARY SEARCH.
ASSIGN COMPONENT <ld_char_val> OF STRUCTURE
<gs_smp_tst_lab> TO <fs_char>.
CONCATENATE 'WA_OUTPUT-' <fs_char> INTO l_field.
ASSIGN (l_field) TO <wa_field>.
<wa_field> = <fs_char>.
read table ist_temp .........
<wa_field> = <fs_char>.
I have done this but <wa_field> actually holds the current data of <fs_char>
it should be like
wa_ouput-f1 = <fs_char>..
wa_output-f2 = <fs_char>.
and the appending it to wa_output to i_output .
How we can do this using field-symbol.
Plz required help.

Hello ,
I have a field symbol where i am not aware of fields (Column Name) , i mean column names are Dynamic.
Problem is i need to read this field symbol value , how can i do it . It will always have 1 record
Example
Field Symbol looks something like this
<FS> Column Name dynamic -
>
A B C
Record
1 2 3
So now i have to refer to Second Column (i.e. is B in this case) , how should i do
What i tried .
1. <FS>-(Column Name in variable in brackets) - It doesnt work , Error Message unable to interpret the number B
2. <FS>[1] - Error out.For a structured data object <s>, you can use the statement
<b>
ASSIGN COMPONENT <comp> OF STRUCTURE <s> TO <FS>.
</b>
to assign one of its components <comp> to the field symbol <FS>. You can specify the
component <comp> either as a literal or a variable. If <comp> is of type C or a structure which
has no internal tables as components, it specifies the name of the component. If <comp> has any
other elementary data type, it is converted to type I and specifies the number of the component.
In the assignment is successful, SY-SUBRC is set to 0. Otherwise, it returns 4. -
Hi expets.
I have some doubt related to Read Line, iknow it's use but it fails when i m using field symbol.
1->
Do w_lines times.
Read line sy-index field value <fs_customer>-name1.
enddo
Here it makes dump because i m using fied symbol. Its type is correct .
But when i use int. table or structure it's wrks fine
2-> when i try to hide a field sybmol it shows dump. what can i do?
actually in a loop i_customer assigning <fs_customer>
write: /<fs_customer>-name1..etc...
hide : <fs_customer>-kunnr.
here it makes dump when i hide
3-> Problem is-
I have two reports on same screen.1 for Customer and another for Vendor.
both have check boxes.
I want to read them from Screen output and for Customer name i have to get the Customer no. for the selected check box.
Same is with the venodr report n same screen.
wen slect Vendor name check box get vendor no.
My issue is that how i should read two reports on same screen for check boxes.
I mean i will make a DO ...ENDDO . and on it i will read for sy-line-1 times.
then hw i will separate that whetehr this read is for Customer or Vendor.
Do i need to set some flag and then hide that flag.
and supoose if Flag eq C at read then its custoer and as it will be V then its Vendor,
All teh Vendor report is Below thw Customer.
Please tell me the advantage of Field symbol over heaer lines of table./

Problem related to field-Symbol?
HI All,
I am writting the below coding, Please tell me whether the Field Symbol will act as a table or not as I want to append a lot of data to field symbol. Please tell me is there any problem in the code.
LOOP AT lt_vepoequi_keys into ls_vepoequi_keys.
READ TABLE lt_vekp ASSIGNING <ls_vekp_str> with key
matnr = ls_vepoequi_keys-matnr.
IF sy-subrc = 0.
<ls_vekp_str>-stoff = ls_vepoequi_keys-stoff.
<ls_vekp_str>-sonum = ls_vepoequi_keys-sonum.
<ls_vekp_str>-lagkl = ls_vepoequi_keys-lagkl.
<ls_vekp_str>-lagkt = ls_vepoequi_keys-lagkt.
endif.
endloop.Hi Abhinav,
you have internal table (say it_employee) with fields name,age,senior_category.
now when you loop this internal table you will need workarea.
loop at it_employee into wa_employee.
if wa_employee-age > 60.
wa_employee-senior_category = 'YES'.
else.
wa_employee-senior_category = 'NO'.
endif.
modify it_employee from wa_employee.
endloop.
now one use of Field-symbols is : when internal table is huge and when you loop with workarea and modify internal table each time, it takes time. So if we use Field-symbols performance would increase.
loop at it_employee assigning into <fs_employee>.
if <fs_employee>-age > 60.
<fs_employee>-senior_category = 'YES'.
else.
<fs_employee>-senior_category = 'NO'.
endif.
endloop.
Now you see in the above code, i have not used modify statement because when i loop internal table, the field symbol points directly to the memory of internal table.
So during loop if i assign any value to the field symbol then it directly changes the internal table value, so there wont be any need to use modify statement.
Hope you are clear with this example....

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

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
