How to pass dynamic name to a field-symbol?

Hi All,
I have a requirement like I need to create dynamic internal table with dynamic name. Say like,
Create a new Table
   CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
     it_fieldcatalog = it_fieldcat_fin[]
    IMPORTING
     ep_table        = new_table.
    IF sy-subrc EQ 0.
Create a new Line with the same structure of the table.
     ASSIGN new_table->* to <b>(<fs_table>)</b>.
In the above code, (<fs_table>) is a variable. Actually it is in the loop, so that first time it comes, it has to create an internal table with name as <fs_01>, next time <fs_02> and so on. Hope I am clear.
Please help me. I am sure that i will mark the helpful answers.

DATA: DREF TYPE REF TO DATA,WA_REF TYPE REF TO DATA.
FIELD-SYMBOLS: <TEMP_TAB> TYPE TABLE, <TEMP_WA> TYPE ANY.
*&      Form DYNAMIC_TABLE
      text
--> p1        text
<-- p2        text
FORM DYNAMIC_TABLE.
CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE
    EXPORTING
      IT_FIELDCATALOG = LT_LVCFIELDCAT
    IMPORTING
      EP_TABLE        = DREF.
ASSIGN dref->* TO <TEMP_TAB>.
ENDFORM.                    " DYNAMIC_TABLE
the above is the procedure to create dynamic internal tables.
now <TEMP_TAB> points to the contents of the table table in DREF.
field symbol it self is meant for dynamic.
then y r u using (<fs_table>).
when everytime the same fieldsymbol is pointing to new contents, y u need new name everytime?
i mean as the data is not static, so what is the use of naming a field symbol every time?.
if u want to store the data in an internal table with a name,
then u can do like below,
data: tabname type string, i type i.
concatenate '<fs_' i into tabname.
"let i be the variable which stores the internal tables count
"MOVE <temp_tab> to tabname.

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.
Thanks,

Hello,
Using dynamic sql you can pass column name to function. well I am not getting what you really want to do ? Please write in more detail. By the way I am providing one example here. see it uses dynamic sql.
Create or replace function fun_updtest (p_columnname_varchar2 in varchar2,
p_value_number in number)
return number is
v_stmt varchar2(500);
begin
v_stmt := 'update emp
set '||p_columnname_varchar2||' = '||to_char(p_value_number)||'
where empno = 7369';
execute immediate v_stmt;
return 0;
commit;
end;
call to this function can be like this..
declare
v_number number;
begin
v_number := fun_updtest('SAL',5000);
end;

i 'm doing what exactly you mention here .
my problem here is
i have 15 columns
i am executing a query based on the values of the column(column name) in the target page
1)here i am passing(all) the column values to the next page-but i want to pass only one column values(column name)
when i click on any cell of that column
OR
2)i can pass all column name to target page -there(in the target page) i can filter out
i think option 1 would good if you filter out the unwanted columns

How to move a dynamic variable to a FIELD-SYMBOL

Hello:
i would like to ask a favor i have been trying to move a dynamic variable to a FIELD-SYMBOL but, when i compile the programm it send a error message that say 'error with assign'.
The FS is declared like this
FIELD-SYMBOLS: <dyn_table> TYPE STANDARD TABLE, <dyn_wa>.
and then there is a PERFORM that send a dynamic varible and then this variable is asigned to the <dyn_table> and after of this one variable is created like this CREATE DATA wa_dynamic LIKE LINE OF <dyn_table>.
and finalilly there is a sentences where i trying to send the wa_dynamic to the <dyn_wa>.
here is where the error appear.
if you have any tips for this problem i will appreciate.
thanks a lot

Create Dynamic Structure based on Field-Symbol

Hi Experts!!
I need to create a structure with dynamic structure included within.
I have a parameter on sel. screen in which we provide table name.
PARAMETERS: p_table TYPE tabname.
FIELD-SYMBOLS: <gt_data> TYPE ANY TABLE.
CREATE DATA gr_data TYPE TABLE OF (p_table).
ASSIGN gr_data-* TO <gt_data>.
Now I need a structure like below:
TYPES: BEGIN OF type_test,
struct TYPE <gt_data>, " dynamic structure based on table name entered on sel. screen
fld1 TYPE c,
fld2 TYPE n,
END OF type_test.
Can somebody suggest how to achieve this?
Your help is highly appreciated. Thanks a lot

You can view this thread where our friend Marcin rocks .. Dynamically create a type
FIELD-SYMBOLS: <gt_data> TYPE ANY TABLE.
FIELD-SYMBOLS: <gs_wa> TYPE ANY.
data:wf_ref type ref to data.
DATA:i_comp TYPE cl_abap_structdescr=>component_table,
i_tot_comp TYPE cl_abap_structdescr=>component_table.
CREATE DATA gr_data TYPE TABLE OF (p_table).
ASSIGN gr_data-* TO <gt_data>.
create data wf_ref like line of <gt_data>.
assign wf_ref->* to <gs_wa>.
*--Getting Compoents from existing type
lf_struct ?= cl_abap_typedescr=>describe_by_name( '<GS_WA>' ).
i_comp = lf_struct->get_components( ).
APPEND LINES OF i_comp TO i_tot_comp.
The idea is Get all the field details available it to i_tot_comp, then append individual fields manually to
i_tot_comp as explained in the link and create a dynamic structure and table.

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.
ENDLOOP.

How to copy the structure of a Field Symbol?

Hi,
          I have a requirement where in a dynamic Internal table is supposed to be created. I have created that dynamic table using the class method cl_alv_table_create=>create_dynamic_table. Here I have a structure in the field symbol. My requirement is how do I create a internal table with the structure that is there in the field symbol?...
and i'm unable to refer to the field that is dynamically created in the field symbol.
Like,
<gfs_tab>-pernr = itab-pernr.
in the above stmt the field pernr is created in the field symbol dynamically.
Thanks,
Deepak.

Hi Matt,
            my objective is to create an internal table with structure that i have obtained in <gfs_tab> .
other than the pernr, there are many fields dynamically generated.
say if I have generated the following structure in <gfs_tab> :
pernr            ename1            day1             day2                 day3
then I want to create an internal table with the above structure so that my internal table will have fields:
1) pernr
2) ename1
3) day1
4) day2
5) day3
for each execution of the report there will be different structure generated in <gfs_tab> depending upon the inputs that I give.
Thanks,
Deepak.

How to assign ranges ( select-option)to field symbol

Hi ,
I have following scenario
ranges : r_test1 for agr_1251,
             r_test2 for agr_1251.
In runtime i am getting which range i have to populate in a field v_rname.for now let it me v_rname = 'r_test2'
i want to assign (v_rname ) to <field -symbol> ie is range to field symbol.
and i want to update the <field -symbol>-sign ='I'
                                    <field -symbol>-LOW ='some value'
                                    append <field -symbol>.
This is the logic i want to follow, for this how should i have to declare the field symbol ? I couldn't assign a range to field symbol . Please help me.
thanks
Murali

Try this
FIELD-SYMBOLS : <field_symbol> TYPE ANY TABLE.
ASSIGN (v_rname) to <field_symbol>.
<field -symbol>-sign ='I'
<field -symbol>-LOW ='some value'
append <field -symbol>.
This should work because your range is a table.
Hope this helps you.

Creating dynamic internal table(Not field symbol table)

Hi Experts,
I am facing problem creating Intarnal table
I have fieldcatalog, I want create dynamic internal table(Not field symbol table).
I have written----
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
   i_style_table             =
     it_fieldcatalog           = it_fldcat
      it_fieldcatalog           = me->gt_fieldcat
   i_length_in_byte          =
    IMPORTING
      ep_table                  = lt_new_table
   e_style_fname             =
    EXCEPTIONS
     generate_subpool_dir_full = 1
     OTHERS                    = 2.
    ASSIGN lt_new_table->* TO <gt_dyn_repdata>.
    CREATE DATA ls_new_line LIKE LINE OF <gt_dyn_repdata>.
    ASSIGN ls_new_line->* TO <gs_dyn_repdata>.
above logic creating dynamic field symbol table.... But I want create normal internal table.

Hi
What do you mean?
It needs to use the field-symbol, this is the price to pay if it wants a dynamic object

How to check data type of the field symbol at run time

Hi,
My code is as following:
      LOOP AT <fs> ASSIGNING <wa_covp_ext>.
        ASSIGN COMPONENT 86 OF STRUCTURE <wa_covp_ext> TO <f_zzname>.
        IF sy-subrc = 0.
          ASSIGN COMPONENT 158 OF STRUCTURE <wa_covp_ext> TO <f_pernr>.
          IF sy-subrc = 0.
              SELECT SINGLE sname INTO <f_zzname> FROM pa0001
                            WHERE pernr = <f_pernr>
                            AND endda GE sy-datum
                            AND begda LE sy-datum.
         ENDIF.
      ENDIF.
    ENDLOOP.
This query is giving dump when <f_zzname> is type P length 8 and decimals 2, because it tries to put PA0001-sname into it which is type C length 30. So I want to check the type of <f_zzname> before the select statement. If it is character 30, then I will write the select statement else not.
How to check data type of the field symbol at run time? If it's not possible, then can somebody suggest a workaround? Thanks.

check this ...
write describe statement ...
field-symbols : <f_zzname> .
data : sname like pa0001-sname,
       typ(10).
assign sname to <f_zzname>.
describe field <f_zzname> type typ.
write : typ. <-- typ contains character type in this case ..
U can check if typ is of character(C) if so .. write the select statement ...
