Assign component - dynamic field

Hey experts,
I want to do this:
ASSIGN COMPONENT (wa_dd08l-fieldname) of structure <wa_deleted> to <ls_id>
but the (wa_dd08l-fieldname) is incorrect, I can't put there those parentheses.
The <wa_deleted> is a dynamic field symbol and I need to get the ID from it, I have the fieldname of the ID in wa_dd08l-fieldname, but
I can't use it in ASSIGN COMPONENT, so how could I get the value of the fieldname (wa_dd08l-fieldname) from <wa_deleted>?
Regards,
Robert

Why do you want to use the parenthesis?
ASSIGN COMPONENT (wa_dd08l-fieldname) of structure <wa_deleted> to <ls_id>
ASSIGN COMPONENT wa_dd08l-fieldname of structure <wa_deleted> to <ls_id>

Dynamic Type assignment to a Field symbol

Hi All,
I am using the below statement in one of my programs.
ASSIGN COMPONENT 1 OF STRUCTURE <lfs_dyn_colwa> TO <lfs_dyn_field>.
It works fine, but if the first field of structure <lfs_dyn_colwa> is a very large character field, only 29 characters are assigned to <lfs_dyn_field>. am I doing something wrong here.
<lfs_dyn_field> is not assigned previously. The table <lfs_dyn_colwa> is a dynamic table with field names known only at run time.
I tried a lot but could not find any solution.
Any help is appreciated.
Thanks,
Mz

Hi Rahul, Keshav
Sorry if i didnt mention before. But i am using type any for both of my field symbols.
In the middle of processing, i am creating a structure for <lfs_dyn_colwa> dynamically as a work area.
I want to assign the first field of the work area to my second field symbol <lfs_dyn_field>.
If first field of the work area is having a character size of more than 30, only the first 29 are getting copied to the field symbol <lfs_dyn_field>.
First field of the table <lfs_dyn_colwa> is of type c10.
second field of the table <lfs_dyn_colwa> is c160.
the first field is copied alright.
the second field is copied only upto the 29th character.
Thanks for the prompt response.

ASSIGN Component ... (field symbol stuff)

Hi,
I want to validate certain fields (KNA1, BUKRS, KOART, FNAME) which are
entered by the user in the transaction XK01. They are being captured in a structure, lets say X_LFA1.
To validate this fields I am being asked to use field symbols using component assign.
Can someone tell me how do I do this ?

Tushar,
Its still not clear to me what exactly you are trying to do.
Is it like you just want to see if those fields exist in the table or not? If yes, you can do like this.
parameter : p_field -- field entered by the user
data : wa_ztable like ztable.
field-symbols : <fs_any> type any.
Assign component p_field of structure wa_ztable to <fs_any>.
if sy-subrc = 0.
Success.
endif.

Assign Component with dynamic structure.

Hi,
I like to get a field from a structure which i read from a customizing table. I think with a snippet it is easy to understand:
FIELD-SYMBOLS: <fs_value>         TYPE Any.
DATA: lv_field type text30,
       lv_structure type but000,
       lv_Structure_name type text30.
select single *
into lv_structure
from but000.
lv_field = 'PARTNER'.
lv_Structure_name = 'LV_STRUCTURE'.
ASSIGN COMPONENT lv_field OF STRUCTURE lv_Structure_name TO <fs_value>.
But this doesn't wok, because it seems, that this statement try to get the fieldname from the variable 'lv_Structure_name'.
If i replace lv_Structure_name with lv_Structure than it works, but this is not what I like.
Any ideas
Stefan

Hi,
with a little addition of a second fs:
FIELD-SYMBOLS: <fs_value> TYPE ANY.
FIELD-SYMBOLS: <fs_struc> TYPE ANY.
DATA: lv_field TYPE text30,
lv_structure TYPE but000,
lv_structure_name TYPE text30.
SELECT SINGLE *
INTO lv_structure
FROM but000.
lv_field = 'PARTNER'.
lv_structure_name = 'LV_STRUCTURE'.
ASSIGN (lv_structure_name) TO <fs_struc>.
ASSIGN COMPONENT lv_field OF STRUCTURE <fs_struc> TO <fs_value>.
it will work.

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.

Reg: Dynamic Field catalog in ALV

Hi ,
Can any one guide me to build a dynamic field catalog in ALV report?
Below is the format which i expect..........
Material    |     Plant1    |    Plant2    |    Plant3    | ....................|    Plant 20      |
Qty
Val
Qty
Val
Qty
Val
Qty
Val
The plant 1 to 20 has to be brought dynamically as headings from T001W table. (Horizontally populate)
Below each plant i need sub-headings "QTY" and "VAL".                                  (Horizontally populate)
List of Materials should be brought vertically from MARA table.                          (Vertically populate)
Can anyone suggest how to bring out this format for populating data accordingly into the o/p format?
Ur help will be appreciated.

Dynamic fields in select statement

Hi all,
   In selection screen we are having period as select option.The values for period are 01 to 16. Based on
      the values entered in selection screen for period we need to select HSLXX from FAGLFLEXT.
   For example if we enter 01 to 03 in selection screen then we need to select HSL01 HSL02 HSL03
       from FAGLFLEXT.
Like this we need to select fields dynamically in select statement. Can any one tell me how to restrict fields dynamically.
Regards,
Swetha

hi Swetha,
the third select statemnet will work for you..
try this..
_Dynamic where clause in select query.._
* With a variable, result: AND rbusa = '5145'
concatenate 'AND rbusa = ' '''' i_tab-zgsber ''''
append where_clause to where_tab.
* Select
select * from zcostfreq

endselect.

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'.

Dynamic Internal Table with Dynamic Fields

Hi all,
My scenario is fairly simple----
--> End user clicks a button on screen and he gets the list of HR tables.
--> Then selects a table and list of all the fields for that table gets displayed.
--> He/she selects the fields they want data to be retrieved for.
So, the requirement is, the dynamic internal table should get created with the fields selected.
The select statement should only retrieve fields which were selected by the end user
and from the table selected by the end user.
I believe the fields selected by end user can be passed by a variable of type string.
something like this---
select (fields)
from (p_table)        " Table selected by end user
into dynamic internal table.   " should contain columns selected by end user"
Appreciate your inputs and guidance.
Warm regards,
Hari Kiran

Modifying value of dynamic field-symbol

I have a requirement in which i need to access columns of a dynamic internal table , manipulate and update back to the dynamic internal table
Names of the columns are also not fixed. This i am determing at the runtime.
Following is the code used :
Loop at <dyn_table> assigning <dyn_wa>.
lv_field = p_fields " This is the field i am taking from the selection screen which needds to be manipulated.
ASSIGN COMPONENT lv_field OF STRUCTURE <dyn_wa> TO <fs_value>.
refresh itab.
split <fs_value> at ',' into table itab.
loop at itab.
assign other fields of the source package to new splited table.
ASSIGN <dyn_wa> TO <dyn_wa1>.
I have to assign the valuein itab to the third field in field symbols.
( so the code would be added here)*******************
append <dyn_wa1> to <dyn_table1>.
endloop.
endloop.
Kindly suggest some solution for this above requiremnt.
Regards,
Amruta

Hello,
Just try to use the below codes in appropriate place and let me know if further issues..
LOOP AT itab.
ASSIGN COMPONENT 3 OF STRUCTURE <dyn_wa1> to <fs_value>.
CLEAR : <fs_value>.
<fs_value> = itab-field name.
APPEND <dyn_wa1> TO <dyn_table1>.
ENDLOOP.
Thanks!

Dynamic field access in internal tables

Hi everyone.
I woulkd like to know if there is any way to identify the fields of an internal table at runtime. I'm creating a method in a class, and i would like to accept any itab as a paramter and then access the fields of that itab. I currently have the itab passing no problem using field symbols, and i am able to loop at the data, but i am unsure how to get the field names.
Any suggestions?
Thanks!

Dynamic Field Symbols with Structures

Hello,
I am stuck on a piece of code and looking for some help. I am trying to figure out how to assign values in a structure of a dynamically defined field symbol to the structure inside another dynamically defined field symbol. Here is my code and some comments. Basically I am uploading data via a flatfile and placing it into a dynamically defined field symbol.
DATA:
lr_area     TYPE REF TO cl_sem_planarea_attributes,
lr_t_data   TYPE REF TO data,
lr_s_data   TYPE REF TO data,
lr_s_chas   TYPE REF TO data,
lr_s_kyfs   TYPE REF TO data.
FIELD-SYMBOLS:

<kyfs> TYPE ANY.
CALL METHOD cl_sem_planarea_attributes=>get_instance
EXPORTING       i_area      = i_area
RECEIVING       er_instance = lr_area.
CHECK sy-subrc = 0.

ASSIGN lr_s_data->*   TO <ls_data>.
CREATE DATA lr_t_data TYPE (lr_area->typename_t_data).

IF sy-subrc = 0.
<ls_data> = ls_charng-low.
ENDIF.
ENDIF.
ENDLOOP.
COLLECT <ls_data> INTO <lt_data>.
ENDLOOP.
Ls_chasel has 2 components:
Chanm (a char 30 which contains the component’s name)
T_CHARNG (a table with values for chanm)
Ls_data has 2 components:
S_chas (a structure with a list of components and values – same list as would have)
S_kyfs (a structure with a list of components and values – same list as would have)
Lt_data is a table of ls_data
I need to get the data in ls_chas into the ls_chas structure of ls_data and the ls_kyfs data into the ls_kyfs structure of ls_chas and append ls_chas to lt_data. Anything that is commented out is something I tried that didn't work. RIght now I get a dump at the 'loop at <chas> into ls_chasel' that the field symbol is not assigned.
Thanks for your help!

It looks like the the original poster didn't completely understand all he was doing. (This is why I always recommend getting an ABAP programmer in for what is, essentially, advanced ABAP programming, rather than someone "kind of familiar" with ABAP trying it - we're often available at very reasonable rates ).
It seems he's using ito_chasel to set the fixed values (which is in fact quite smart!). What isn't required, so far as I can tell without implementing, are any of the statements involving <ls_kyfs> or <ls_chas>.
The following should be sufficient (with the necessary declarations etc. - but really: omit <ls_kyfs> and <ls_chas> - I'm sure they're not needed and they confuse things).
" Go through the data from the flat file
LOOP AT gt_file INTO ls_file.
CLEAR <ls_data>.
" Transfer the characteristics
MOVE-CORRESPONDING ls_file TO <s_chas>.
" Transfer the key figure
MOVE-CORRESPONDING ls_file TO <s_kyfs>.
" Go through the fixed characteristic selections from the package
LOOP AT ito_chasel INTO ls_chasel.
    " We only care about the first value (if there is one).
    READ TABLE ls_chasel-s_charng INTO ls_charng INDEX 1.
    " Check there is a first value and that it is fixed
    CHECK sy-subrc IS INITIAL AND ls_charng EQ 'EQ'.
    " Get access to that characteristic
    FIELD-SYMBOLS <fixed_value> TYPE ANY.
    ASSIGN COMPONENT ls_chasel-chanm OF STRUCTURE <s_chas> TO <fixed_value>.
    " Make sure that it exists in the data structure
    CHECK sy-subrc IS INITIAL.
    " Set the value
    <fixed_value> = ls_charng-low.
ENDLOOP.
COLLECT <ls_data> INTO <lt_data>.
ENDLOOP.

Read Dynamic Field Symbol

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.

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 -->

TYPES: BEGIN OF line,

DATA: wa TYPE 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.
