Are field symbols and Dynamic internal tables consistant?

Hi,
Are field symbols and Dynamic internal tables
always consistent?
In my program I m creating a dynamic itab and assignig values to it using <FS>, sometimes the program fails to execute assign <Fs> statement...
this happens once in 3 to 4 runs
any solution...
I have proper clear and refresh statements in program.
Thanks,
Hardik

Anurag,
Thanks for a quick reply. Here I am sending a small piece of my code.
MOVE-CORRESPONDING OUTTAB TO DYNTAB.
      CLEAR IT_UDATE.
      CLEAR : T_KBETR .
      READ TABLE IT_UDATE WITH KEY UDATE = OUTTAB-UDATE.
      CONCATENATE 'DYNTAB-KBETR' IT_UDATE-CO_POS INTO T_KBETR.
      ASSIGN (T_KBETR) TO <FS> .
      SUBRC5 = SY-SUBRC .
      IF SUBRC5 = 0 .
          <FS> = OUTTAB-KBETR .
      ENDIF .
read statement will always return CO_POS .
while debuging this code a few times
<b>ASSIGN (T_KBETR) TO <FS> .</b>
returns sy-subrc = 4
and that was leading the program to short dump earlier.
now, as I have a check DYNTAB-KBETR holds no value on display.
this happens very few times. (most of the times report is displaying desired output)
Thanks,
Hardik

Field symbols and delete internal table.

Hi,
I wish to implement <fs> in this case:
LOOP AT intable ASSIGNING <fs> WHERE condition
IF condition1.
    DELETE intable
ANDLOOP
I know that if the condition1 is verified, the <fs> will be unassigned but in this case I lose the loop.
Any Idea? ... Or is it impossible to handle?
Thanks in advance.

If you know the standard table name in the start routine , then you can create a dynamic structure after adding a field flag, then you can use that as
call function 'LVC_FIELDCATALOG_MERGE'
    exporting
      i_structure_name = p_table
    changing
      ct_fieldcat      = i_fcat
    exceptions
      others           = 1.
if sy-subrc = 0.
    loop at i_fcat assigning <fcat>.
      <fcat>-tabname = p_table.
      <fcat>-fieldname = 'FLAG'
      .... " after giving other attributes for the flag field
     append <fcat> to i_fcat.
    endloop.
    call function 'LVC_FIELDCAT_COMPLETE'
      changing
        ct_fieldcat = i_fcat
      exceptions
        others      = 1.
endif.
call method cl_alv_table_create=>create_dynamic_table
    exporting
      it_fieldcatalog = i_fcat
    importing
      ep_table        = i_content.

    assign i_content->* to <fs>.

Data from field symbol into an internal table or workarea

Hi Experts,
I have field symbol in which i get the data. I want to get this data into an internal table of type any or into an work area. How is this possible.
My declaration for field symbol is as follow:
FIELD-SYMBOLS: <l_t_data> TYPE any.
DATA l_r_data TYPE REF TO data.
    CREATE DATA l_r_data type STANDARD TABLE OF (l_local_tab).
    ASSIGN l_r_data->* TO <l_t_data>.
I get the data in this field symbol <l_t_data>. by passing into a funtion module. and I get the data into it. Now i have to assign the values of this field symbol to any internal table or to a work are how do i do it. Please help.
Regards,
Prashant.

Not exactly sure what you need here, but.....
FIELD-SYMBOLS: <l_t_data> TYPE TABLE.   "<<-- Change this
FIELD-SYMBOLS: <l_s_data> TYPE ANY.      "<<---Add This
DATA l_r_data TYPE REF TO data.
CREATE DATA l_r_data type STANDARD TABLE OF (l_local_tab).
ASSIGN l_r_data->* TO <l_t_data>.

Field Symbols
http://help.sap.com/saphelp_46c/helpdata/EN/fc/eb387a358411d1829f0000e829fbfe/frameset.htm
Field symbols: are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to each field symbol before you can address the latter in programs.
Field Groups:
A field group is a user-defined grouping of characteristics and basic key figures from the EC-EIS or EC-BP field catalog.
Use
The field catalog contains the fields that are used in the aspects. As the number of fields grows, the field catalog becomes very large and unclear. To simplify maintenance of the aspects, you can group fields in a field group. You can group the fields as you wish, for example, by subject area or responsibility area. A field may be included in several field groups.
When maintaining the data structure of an aspect, you can select the field group that contains the relevant characteristics and basic key figures. This way you limit the number of fields offered.
A field group combines several existing fields together under one name
like
FIELD-GROUPS: fg.
then you can use one insert statement to insert values in fields of field-group.
INSERT f1 f2 ... INTO fg.
Field symbols
If u have experience with 'C', then understand this to be similar to a pointer.
It is used to reference another variable dynamically. So this field symbol will simply point to some other variable. and this pointer can be changed at runtime.
FIELD-SYMBOLS <FS>.
DATA FIELD VALUE 'X'.
ASSIGN FIELD TO <FS>.
WRITE <FS>.

Dear All,
                In need to pass tabular data i.e. multiple entries from field symbol to the table parameter of the custom function module.
Field symbol is declared as below:
FIELD-SYMBOLS: <FS_EXCEL_TAB> TYPE STANDARD TABLE,
                             <FS_TABLE_HEADER> .
DATA WA_PD LIKE PRICE_DOWNLOAD.
APPEND <FS_TABLE_HEADER> TO <FS_EXCEL_TAB>.
CLEAR <FS_TABLE_HEADER>.
WA_PD-VKORG = <FS_EXCEL_TAB>-VKORG.u201D Problem while using this statement
APPEND WA_PD TO PRICE_DOWNLOAD.
   CLEAR WA_PD.
Field symbol <FS_EXCEL_TAB> is populated like this.
VKORG | KUNNR_SH | KUNNR_SP |

sorry, question resolved.

I am stuck in FIELD-SYMBOLS and dynamic tables.

Hi guys,
            I am trying to create dynamic table. My requirement is as follows--
I have to display grid layout report in depending on given input.
In input i have fields for DC and STORE.
In output i have to display columns depending on number of DC and STORE paased in input.
For example if in input, i have 2 DCs DC01 and DC02 and in STs i have say 1 input - ST01
then in outpt grid report there will be 3 columns.
So my columns to be displayed depends on number of input values given while running it.
I am trying to use dynamic table.
My output report contains fields from different table...so i cant use
FIELD-SYMBOLS: <DYN_TABLE> TYPE STANDARD TABLE
instead i m trying to use
FIELD-SYMBOLS: <DYN_TABLE> LIKE T_ARTMAS "T_ARTMAS is declared as types : begin of....end of .... .
but it is giviing an error in following form

Hi

but it is giviing an error in following form.....
Just as Sasha wrote, the problem could be you've defined a flat structure and u need a table, but now just a little a question: why do u want to use a dynamic table but your field-symbol is like a certain type?
That means u know how the table is so u don't need to use a dynamic table, your issue seems not to make sense.

Need Help in Field Symbol for Dynamically passing table field value

Hi All,
In my internal table I am having data.
I am dynamically forming table field name and substitute for the another table field name to pass DATA.
but I am getting the Variable name insted of Value ie Data.
I am using Field Symbol for this.
data:
Field-symbols <TS> type any.
field1 type string.
LOOP AT TABLEFIELDS INTO WA_TABLEFIELDS.
            READ TABLE TEST WITH KEY NAME = WA_TABLEFIELDS-FIELDNAME.
            IF SY-SUBRC = 0.
              CONCATENATE 'WA_' WA_TABLEFIELDS-TABNAME '-' WA_TABLEFIELDS-FIELDNAME INTO Field1.
              Assign Field1 to <TS>.
                ALL_VAL-VALUE = <TS>
"After substituting the <TS> into ALL_VAL-VALUE field I need a DATA to be passed but the variable name is appending"*
         APPEND ALL_VAL.
            ENDIF.
          ENDLOOP.
kindly how to pass the value into the table.
Thanks in advance.
San

Hi,
pls assign a break point in
CONCATENATE 'WA_' WA_TABLEFIELDS-TABNAME '-' WA_TABLEFIELDS-FIELDNAME INTO Field1.
Assign Field1 to <TS>.
ALL_VAL-VALUE = <TS>
   " Put a break point here and check for the value in <TS>.
if <TS> contains value then create a work area for ALL_VAL AND PASS the Field-Symbol to that and then append thw wa into the table...
Hope this works out!!

Accessing the variable in field symbol of nested internal table

Hi,
I am unable to access the variable in field symbol.
The data in field symbol has nested structure. We need to access a variable in nested structure.
Please find the code below:
      LOOP AT <i_fincorp> into <fs_fincorp>.
        l_madefor = <FS_FINCORP>-data_UI-ZZ0010.
      ENDLOOP.
datatype of <i_fincorp> is type any table and <fs_fincorp> is type any.
there is a structure 'data_ui' in <i_fincorp> and we need value of field 'ZZ0010' in data_ui structure.
But, we are getting syntax error for statement in loop stating "There is no component like 'data_ui' in <fs_fincorp>".
Can anyone please help me solving this issue.
Regards,
Santosh

So simply access it dynamically
data: nested_field type c length 50.
field-symbols <nested_field> type any.
"build the nested field name dynamically
concatenate
       'DATA_UI'    "first give structure name
       'ZZ0010' "then give field name (all in uppercase!)
into nested_field
separated by '-'. "now you have DATA_UI-ZZ0010
"so assing this nested field
LOOP AT <i_fincorp> into <fs_fincorp>.
   assign component (nested_field) of structure <fs_fincorp> into <nested_field>.
ENDLOOP.

Field Symbols and Dynamic references

Hello,
I have Two internal tables Itab1 and Itab2 which are containing MATNR as field.
Itab1-matnr contains the value as 123;456;789.
I have two more Field-symbols Var1 and var2 which contains the values as <Var1> = itab1-matnr
                       <var2> = itab2-matnr.
now i wanted to split contents of Itab1-matnr.
split <var1> at ';' into <var2> <var1>.
By this, my expected result is 123 into Itab2-matnr and 456;789 into itab1-matnr.
How can i do this? now Var1 contains the value as itab1-matnr, but not the contents of itab1-matnr ( But not 123;456;789) .
Pleasde help me in solving this.

Hello Rajesekhar,
U can try this...
I have used fields instead of internal table.
data: itab1 like mara-matnr value '123;456;789',
      itab2 like mara-matnr.
data: begin of itab3 occurs 0.
data: fld(50).
data end of itab3.
field-symbols: <fs1> type any,
               <fs2> type any.
assign itab1 to <fs1>.
assign itab2 to <fs2>.
search <fs1> for ';'.
sy-fdpos = sy-fdpos + 1.
<fs2> = <fs1>(sy-fdpos).
<fs1> = <fs1>+4.

Are field symbols and Dynamic internal tables consistant?
