Changing screen feild values through field symbols

hi
I am working on SAPMF02D user exit, it requires validation of searchterm1 feild, I have successfully completed this part with the help of field symbols, but the problem i am facing is that, after performing validation checks, searchterm1 feild would be updated, this I am not able to do, so far I have done the following:
DATA: fld(30) VALUE '(SAPLSZA1)ADDR1_DATA-SORT1'.
FIELD-SYMBOLS: <f1> TYPE ANY .
* Assign screen field values to field symbol
ASSIGN (fld) TO <f1>.
* get the value from field symbol into our field
IF <f1> IS ASSIGNED.
acc1 = <f1>.
ENDIF.
.. *Perform validation and updation on 'acc1'
* get the updated values back into screen feild
<f1> = acc1.
now this last thing is not working for me,, and the data does not get updated in screen/database....
I have tried using ' comit work' statement , but no use,
I require help on this issue and its quite urgent.
Thank you all for your time.

Thank you again for the reply,
I am sorry , I am not able to use to that FM either,, I just cannot understand the parameters it is taking and how to provide them.
I have already used the FM "DYNP_UPDATE_FIELDS" and "DYNP_UPDATE_FIELDS" , as:
<f1> = acc1.
scrfields-fieldname = 'ADDR1_DATA-SORT1'.
scrfields-fieldvalue = <f1>.
APPEND scrfields.
CALL FUNCTION 'DYNP_VALUES_UPDATE'
EXPORTING
    dyname                     = 'SAPLSZA1'
    dynumb                     = '0301'
TABLES
    dynpfields                 = scrfields[]
* EXCEPTIONS
*   INVALID_ABAPWORKAREA       = 1
*   INVALID_DYNPROFIELD        = 2
*   INVALID_DYNPRONAME         = 3
*   INVALID_DYNPRONUMMER       = 4
*   INVALID_REQUEST            = 5
*   NO_FIELDDESCRIPTION        = 6
*   UNDEFIND_ERROR             = 7
*   OTHERS                     = 8
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
but it did not helped my cause either..
Any help would be highly appreciated,
thank you

How to populate values of field symbols?

HI,
I need to pass values into a field-symbol (defined as a dynamic Work Area) and append the values later on into another field-symbol (defined as a dynamic Table) by inserting the work area to the table. The insert statement in the screen shot below is syntetically correct but when I uncomment
*      <gw_itab>-tplnr = 'TPLNR'.
*      <gw_itab>-pmsog = 'PMSOG'.
*      <gw_itab>-k_pro = 'K_PRO'.
I get a syntax error. During debugging if I pass the values of the work area, they are properly appended into the table.
Could somebody show me the code on how to atain this programatically?
Thanks for your help
Carl

From the short dump:
"<GT_ITAB> has line type "v" and the length 24, but the work area has line type "g" and the length 8".
The code you included in your first screenshot is not the code that it dumped on... Looking at the shortdump here's what you have.
lv_fieldname = '<GW_ITAB>-TPLNR'.
assign (lv_fieldname) to <gw_itab>.
<gw_itab> = 'TPLNR'.
insert <gw_itab> into table <gt_itab>.
This code doesn't make any sense...
What you're saying is:
<gw_itab> points to <gw_itab>-tplnr. So now it points to just a field of the structure, not the whole structure.... Then you say that field is set to 'TPLNR'. So you set the field of the original structure called TPLNR to be the string "TPLNR"...
If that's really what you're trying to do then try changing it to:
field-symbols: <field> type any.
lv_fieldname = '<GW_ITAB>-TPLNR'.
assign (lv_fieldname) to <field>.
<field> = 'TPLNR'.
insert <gw_itab> into table <gt_itab>.

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.
Pavan.

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.

To Modify a field value with field symbols

we had a requirement like we are getting in a floating point value in a field of an IDoc segment like 12.327- .Here if we see that the negative sign is after the floating point value and if we try to insert this into a database then it will throw out an error.Before inserting the value we need to covert the incoming value in the form -12.327.
I used the field symbols inorder to get the values and to change them.

Hello.
When you write,
LOOP AT it_mbew ASSIGNING <fs1>.
ENDLOOP.
you don't need to use statements:
ASSIGN WA_MBEW TO <FS1>
nor
MODIFY it_mbew
after that.
If you just write:
LOOP AT it_mbew ASSIGNING <fs1>.
<fs1>-field1 = 'A'.
<fs1>-field2 = 'B'.
ENDLOOP.
all records of it_mbew will have field1 = 'A' and field2 = 'B'.
The point is, statement LOOP assigning <fs1> will make the field symbol to became a pointer to the records of the internal table. So, if you change the field symbol, you are changing the internal table already.

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>.

Assigning object reference values to field symbols

Okay.......has anyone out there figured out how to assign the reference value of an object (you know the value you see in the debugger for example: .........to a field symbol.
I know there has to be a way and was wondering if anyone has successfully achieved this. Its easy to assign a memory area to a field symbol if its an itab like this below:
field-symbols: <fs>.
data: v_fieldname(20) type c.
v_fieldname = '(SAPLMEREQ)MARA'.
assign (v_fieldname) to <fs>.
This shouldn't be impossible with code like:
field-symbols: <fs> type ref to object.
data: v_ref(100) type c.
v_ref = '{O:666*\FUNCTION-POOL=MEREQ\CLASS=LCL_REQ_ITEM_STATE}'.
assign (v_ref) to <fs>.
I just know that the code above doesn't work....
Any suggestions? And please......no questions about "why" or "what do I want to accomplish?" .....

Change Screen Attributes of Standard Fields on ME22N

Hello Fellows.
I'm facing a problem trying to change a screen attribute of a ME22N standard field at Item Detail:
My requeriment:
I need to change the Delivery Completed Indicator (MEPO1313-ELIKZ) from Delivery Tab in ME22N, to Display Only, everytime it's flagged on (marked).
So, something like this:
- Call ME22N
- Delivery Completed Indicator marked?
- Yes: Change it to Display Only
- No: Leave it openned.
I was able to change it to Display Only changing it's atrribute at SPRO - Customizing, but I need it only at certain conditions.
Any idea?
Thank's.

Thank you for your reply Weston.
Since I don't have too much OO skills and I'm new to BADI's, any document explaning how to use a BADI?
I heard about this BADI, that it can only change custom fields attributes. Have you sure I can use it for standard one's?
Thank's.

How to Remove Previous Values in Field Symbols

Hi,
My code goes like this.
Loop at i_vbap.
read table itab assigning <fs>.
if sy-subrc = 0.
endif.
Endloop.
This is good if my subrc for read is always 0. however, if my subrc = 4, my <fs> still contains the previous values. How do i clear my <fs> with the previous values?
Thanks,
Jim

Hi
In your code please do the following
Loop at i_vbap.
Unassign <fs>.
read table itab assigning <fs>.
if sy-subrc = 0.
endif.
The problem would arise if you are using <fs> below without it being assigned.
It would cause a short dump.
So change your coding appropriately.
Endloop.

Is there a way of changing the alpha value of a symbol in its own timeline without ActionScript

I'm trying to make an animated banner ad where radio waves emanate from a device as they fade in and fade out.
I got it working, then realized I'd like the radio wave animation to loop repeatedly while the text in the ad comes in and out, so I thought maybe it should be a symbol and have the animation take place in its own timeline.
Problem is, when I make the symbol and double click to enter its timeline, the color effect menu disappears.
I don't feel comfortable in ActionScript yet. Is there no other way to do what I want?
Can I create the radio waves as a separate animation file, then import it into the main animation?

You should be able to make seperate keyframes and then modify the alpha of any MovieClip or Graphic objects within that keyframe. After that right click somewhere between the keyframes on the timeline and select "Create Classic Tween".
NOTE: You have to have the keyframe selected on the timeline to be able to modify properties. So if you have a keyframe on frame 1, frame 10 and frame 20 set the alpha on frame 1 at 100%, frame 10 at 0% and frame 20 at 100% and it will fill in the blanks.
EDIT:
If the objects in your inner symbol are not a MovieClip or Graphic select all and then Right Click and select "Convert to Symbol" to make them one.

Field symbols for fetching ME51N screen data

Hi,
I need to fetch ME51N or ME52N screen data.
In old Transaction (ME51,ME52) there is this code that work:
data:wa_eban like eban.
data:wa_rm06b like rm06b.
data:va_epstp like rm06b-epstp.
data:va_knttp like eban-knttp.
field-symbols <va_eban> structure eban default wa_eban.
field-symbols <va_rm06b> structure rm06b default wa_rm06b.
assign ('(SAPMM06B)EBAN') to <va_eban>.
assign ('(SAPMM06B)RM06B') to <va_rm06b>.
move <va_rm06b>-epstp to va_epstp.
move <va_eban>-knttp to va_knttp.
if not <va_eban>-loekz is initial.
exit.
endif.
This code is used in a FIELD EXIT for compare Data in some Fields.
In the New Transaction i can't use this code because EBAN and RM06B is empty and return null.
Can any one tell me if there are Program/Structure combination that return EBAN and RM06B Data?
Or alternatively whether any better method available for fetching screen data?
Thanks & Regards
Angelo

For more Info see this thread, similar problem is solved, but in ME52N change some things.

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 ,

Field Symbol not writing the values while executing in background.

Hi,
In my program i am writing the values of a field symbol to list output.
write :/ <f_fs_up_excel_wa2>.
Its writing successfully when i am executing in foreground.
But when i am executing in background(Submitting the same program as a job)
its not displaying the values from field-symbol but all the other write statments are getting displayed in the spool.
Could anybody help me out in this situation and how to handle it?
Thanks,
SAM.

Hmm. I think the problem is that the field-symbols is blank in background processing, rather than background process has some fault that prevents it being displayed...
On that basis - how is this field-symbol populated?
