Moving a value to a component of a field symbol

Hi,
I have a problem with a piece of code comparable to this one:
FIELD-SYMBOLS:
<structure_A> TYPE ANY,
<structure_B> TYPE ANY,
<component_name> TYPE ANY.
<component_name> = 'WHATEVER'.
" <structure_A>-<component_name> = <structure_B>-<component_name>.
The intention is to copy a value from a component of one structure to the same component of another structure. The crux is that the structures are defined dynamically and the component's name is known during runtime only.
Assume that the example is well-defined, i. e. all field symbols are initiated with suitable values.
--Florian

hi Florian,
when the structure is only known during run time, you have to ASSIGN each field separately, something like this:
FIELD-SYMBOLS : <field_A> TYPE ANY,
<field_B> TYPE ANY.
ASSIGN COMPONENT 'WHATEVER' OF structure <structure_A> TO <field_A>.
ASSIGN COMPONENT 'WHATEVER' OF structure <structure_B> TO <field_B>.
<field_B> = <field_A>.
you have to repeat the above for each single field you want to copy its value
hope this helps

Assign a value to a component of a field-symbol

Hi,
I'm struggling with field-symbols, hope someone can help me with this:
I have two field-symbols:
- <row> which for example can have structure E1P0002 assigned to it;
- <row_it> which for example can have stucture P0002 assigned to it.
Certain components of <row> should be assigned to components of <row_it>. The names of the components differ however. For instance: component STRAS_40 of <row> should be assigned to component STRAS of <row_it>, NAME2_40 of <row> should be assigned to NAME2 of <row_it>, etc.
Depending on the structures assigned to the field-symbols, these fields are not always available.
Any ideas how this can be solved?
Thanks,
Patrick

Hi do as follows,
<row_wa> is the structure of type P0002
and <row_it> is a field symbol of table type
and another field symbol <fs> type any.
if <row>-STRAS_40 is not initial.
assign component STRAS of structure <row_wa> to <fs>.
<fs> = <row>-STRAS_40 .
endif.
if <row>- NAME2_40 is not initial.
assign component NAME2 of structure <row_wa> to <fs>.
<fs> = <row>-NAME2_40 .
endif.
append <row_wa> to <row_it>.
Hope this explanation of mine helps you,
Murthy.

Move a variable to a component of a field-symbol structure ???

I have a field symbol <fs_struc> that's typed as a structure from the dictionary.
I want to move a variable to a particular component of this structure, and I've put the name of his component in another field symbol <fs_comp>.
1) Why doesn't the following syntax work?
ASSIGN variable TO <fs_struc>-<fs_comp>
(Note that there's a hyphen between <fs_struc> and <fs_comp>)
2) What is the correct syntax to do this ?
Thanks.

Hi David,
1) If you've assigned <fs_comp> to a field in a structure, then you have the memory address of the component within the structure. This is why the syntax does not work, because <fs_comp> contains the reference already to the structure (eg. <fs_comp> = structure-field, while <fs_field>-<fs_comp> = structure-structure-field). You can instead use:
ASSIGN variable TO <fs_comp>, if <fs_comp> was already assigned to a field of a structure.
2) If your scenario is that you don't know the field of the structure you want to assign in advance, you can try something like the following. Snippet just shows how you can dynamically assign a field of a structure to another field symbol.
data: ls_kna1 type kna1.
data: lv_comp_name(5) type c value 'NAME1'.
data: o_data type ref to data.
field-symbols: <fs_data> type kna1.
field-symbols: <fs_comp> type any.
ls_kna1-name1 = 'Testing'.
CREATE DATA o_data TYPE (lv_comp_name).
ASSIGN o_data->* TO <fs_comp>.
assign ls_kna1 to <fs_data>.
ASSIGN COMPONENT lv_comp_name OF STRUCTURE <fs_data> TO <fs_comp>.
write: <fs_comp>

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.

Error in Moving values to field symbols. - CX_SY_CONVERSION_NO_NUMBER

Hi Friends,
I have asigned the component 'ICON' to the field symbol . While i am adding the value to the field symbol it is going for Dump.
Erro Message :
Unable to interpret "@08\QGreen Light; Go; Okay@ " as a number.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_CONVERSION_NO_NUMBER', was not
     caught and
    therefore caused a runtime error.
    The reason for the exception is:
    The program attempted to interpret the value "@08\QGreen Light; Go; Okay@ " as
     a number, but
    since the value contravenes the rules for correct number formats,
    this was not possible.
Code :
ASSIGN COMPONENT 'ICON' OF STRUCTURE <line> TO <fs_icon>.
add wa_result-icon to <fs_icon>.
Please find the information and i waiting for your valuable anwers.
Thanks,
Shankara Narayan

HI,
What do you mean by adding the value?
Do you want to move the value of wa_result-icon to the field-symbols <fs_icon>.
use move statement or use '=' operator.
ADD will try to do an addition.
You cannot add character fields. It will surely give a dump.
Do as follows:-
Move wa_result-icon to <fs_icon>.

Problem with field-symbol values not updating

H i ,
      I have following piece of code :
Assigning Dynamic Table to Field Symbol
    ASSIGN ist_dyn_table->* TO <gs_dyn_table>.
*   Creating Structure for dynamic table
    CREATE DATA gs_dyn_line LIKE LINE OF <gs_dyn_table>.
*   Creating line type for the Dynamic Values
    ASSIGN gs_dyn_line->* TO <gs_line>.
*   Populating values in the dynamic table
    LOOP AT ist_pwcl_main INTO wa_pwcl_main.
      ASSIGN COMPONENT gc_fld_werks OF STRUCTURE <gs_line> TO <gs_field>.
   1   IF sy-subrc EQ 0.
   2        <gs_field> = wa_pwcl_main-werks.
   3      ENDIF.
   5 IF <gs_field> IS ASSIGNED.
   6     <gs_field> = wa_pwcl_main-vbeln.
      ENDIF.
7 IF <gs_field> IS ASSIGNED.
8 <gs_field> = wa_pwcl_main-posnr.
      ENDIF.
   IF <gs_field> IS ASSIGNED.
        <gs_field> = wa_pwcl_main-quant.
      ENDIF.
on debugging at line 2 <gs_filed> contains the value of werks .
but at line 6 <gs_field> contains value of vbeln as 0 and at 8 of posnr as 0 .
What can be the problem ? Other values are getting assigned properly .
Plz help ...

Hi,
Assigning Dynamic Table to Field Symbol
    ASSIGN ist_dyn_table->* TO <gs_dyn_table>.
Creating Structure for dynamic table
    CREATE DATA gs_dyn_line LIKE LINE OF <gs_dyn_table>.

      ENDIF.
   IF <gs_field> IS ASSIGNED.
        <gs_field> = wa_pwcl_main-quant.
      ENDIF.
Based on your coding above, <gs_field> has been assigned with data type 'WERKS' (i'd assume component gc_fld_werks found from structure <gs_line> is a plant typed), which is a CHAR(4) data type.
Meaning, if <gs_field> is assigned with Plant type value, e.g. <gs_field> = '1000', field symbol <gs_field> will contain 4 character only.
At line 6, if wa_pwcl_main-vbeln = '0000201000', <gs_field> is only capturing '0000' only. This is also happened to line 8.
However, it looks like that <gs_field> is getting over-write if ASSIGNED statement returns SY-SUBRC = 0.
Hope this helps.

How to check the length of a field symbol value

hi all,
i have a problem with string function, i have assined table fields to a field symbol in a loop i want check the length of the assigned fields symbol value in every loop . i have written like ,,,,,len = strlen( <fs>). then i am getting the length of the field label what i ahve assigned to fiels symbol not the field value lenght ,
please advise me on this,
thanks,
sre

I think you're on the right track. This should work:
data: len type i.
data: begin of itab OCCURS 1,
        a type string value '1',
        b type string value '12',
        c type string value '123',
      end of itab.
FIELD-SYMBOLS: <fs> type ANY.
do 3 times.
assign component sy-index of STRUCTURE itab to <fs>.
len = strlen( <fs> ).
enddo.

Passing field symbol value to a variable

Hi All,
I have a value in Field Symbol declared as   <FS-STATUS> TYPE STANDARD TABLE.
I want to use the value <fs-status> -low in a case statement.
For this i think i have to pass the <fs-status> -low into a variable and then use in case statement.
Can anyone explain how to pass values in field symbol to variable? Or if this is not possible is there any other solution.
Thanks in advance.

Hi ,
I have give some code sample ; just check ..
DATA: BEGIN OF line,
         col1(1) TYPE c,
         col2(1) TYPE c VALUE 'X',
       END OF line.
FIELD-SYMBOLS <fs> LIKE line.
ASSIGN line TO <fs>.
MOVE <fs>-col2 TO <fs>-col1.
WRITE: <fs>-col1, <fs>-col2.

Can i use one JSF component's value for other component in the same page.

Can i use one JSF component's value for other component in the same page.
For example
I have a <h:selectBooleanCheckbox id="myChk"> in my jsf page, i want to access its value for another component like:
<h:commandButton disabled="#{myChk.checked}" action="myAction" value="myValue" />
** "myChk.checked" >> I am just asuming "checked" property is available...

Bind the checkbox to a UIInput myChk property. Then you can reference this property from the page, e.g.
<h:selectBooleanCheckbox binding="#{myBean.myChk}" onchange="submit();" />
<h:commandButton disabled="#{myBean.myChk.value}" action="myAction" value="myValue" />

How to pass a value to a component

instructorView.myVar= e.currentTarget.data
and
instructorView.test()
but both fail. How do I access the properties and methods for this component from the function named click()?

I guess you are getting a null object reference error. This has nothing to do with our instructor view code. It is the creationpolicy of the view stack. The component is not created when you assign values.
This is a link to livedocs page on creation policy.
http://livedocs.adobe.com/flex/3/html/help.html?content=layoutperformance_05.html
To solve your problem, either you can set creationPolicy="all" for viewstack or wait for the component to be instantiated completely

Need to bind value attributes of Component controller with value attributes

Hi,
I am developing a Java Web Dynpro application which is importing RFC Model.

Hi Kaushik,
It is very simple to enter values in webdynpro and to update the ztable through RFC
All you hav to do is
1. Create the ztable , RFC to import data into that table,
2. Create the model in webdynpro with that RFC
3. First map the ModelInputElements to the component controller(say zid, zname) (you can have your own value attribute in component controller say id , name )
4. Map the attributes to the view where the input field is there
5. Now write the code as follows,
Zxxx in = new Zxxx();
wdContext.nodeZxx_InputElement.bind(in);
in.setZid(wdcontext.currentContextElement().getId()); // getId component controllers attribute and getZid is model' s mapped attributre
in.setZname(wdcontext.currentContextElement().getName()); // getName component controllers attribute and getZname is model's mapped attributre
/* u need not have to map that model attrobute to component attribute for that */
try
in.execute();
Catch(Eception e)
e.printStackTrace();

How to access the value of a field of a field symbol.

Hello All,
i need to access the value of a field in a field symbol. But when i am trying to get the value like <FS>-POSNR, it's showing that that the <FS> has no structure.
In my program, the field itself that i need to check should be dynamic. ie i'll get the field in a variable and i need to find the value of that field.
Am pasting my code below, please tell me what needs to be done.
here in my sample code i am moving the entry of the <FS> into a work area structure. But in my actual program, i gets the structure as a parameter. So is there any way i can declare a work area dynamically...
FUNCTION z_39181_dyn_fs_60758.

    lw_lips = <fs>.
    WRITE lw_lips-vbeln.
    ASSIGN (lv_fld) TO <fs1>.

Use syntax
ASSIGN COMPONENT name OF STRUCTURE struc TO <fs>.
