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 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.

hi check this...
For a structured data object s, you can use the statement
ASSIGN COMPONENT comp OF STRUCTURE s TO FS.
Here the comp is the component name or its index number in the structure.
Find the following sample code -
DATA: BEGIN OF LINE,
COL1 TYPE I VALUE '11',
COL2 TYPE I VALUE '22',
COL3 TYPE I VALUE '33',
END OF LINE.
DATA COMP(5) VALUE 'COL3'.
FIELD-SYMBOLS: <F1>, <F2>, <F3>.
ASSIGN LINE TO <F1>.
ASSIGN COMP TO <F2>.
DO 3 TIMES.
ASSIGN COMPONENT SY-INDEX OF STRUCTURE <F1> TO <F3>.
WRITE <F3>.
ENDDO.
ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>.
WRITE / <F3>.
The output is:
11 22 33
33
I need to update one field in Internal table

Copy the structures in a query

hi,
Can we copy the structure of one query to another query ?
If so, please let me know how to do it.
Thanks in advance.

Hi,
If the queries in question are on the same Infoprovider, then you can save the structure as a global structure and use it in both the queries.
If the queries will be on different InfoProviders, then you would need to copy at the query level using RSZC.
Hope this helps...

How to find the Ranges for a field ?

Hello All,
 Can anyone tell me how to find the ranges for a field.
1, i.e say I want the Ranges Structure for the field LIFNR.
 The ranges structure for this is "RANGE_LIFNR".
 This I used in my Program since I know it previously.
 But now I want the ranges structure for the field VBELN (Delivery Document).
 I don't know what is it !!!!!
2, Is there any procedure to know the ranges structure for a particular field ?
Regards,
Deepu.K

Hi Deepu,
Using 'Where used list' you can able to find out RANGES tables.
For VEBLN range table is --> CRM_AC_ASSIGN_VBELN
If you using a program defined as shown below.
DATA: r_vbeln type ranges of vbeln.
The above statement also creates ranges structure in Runtime.
Procedure finding range table structures
go to SE37 -> Enter domain or dataelement value
Go to where used list --> search for 'Structures'
After getting all structure --> Click 'SEARCH' butoon in tool bar --> Search for 'RANGES' word
You can get all ranges tables in the search window
If helps plz reward points.

How to access a field of a structure with a field symbol?

Dear all,
Currently I'm trying to access the fields of a structure (called "ls_tbl") dynamicly. The code looks as follows (of course the field symbols are defined correctly ;-):
 ASSIGN lv_f1 TO <lv_f1>.
 ASSIGN lv_f2 TO <lv_f2>.
 lv_pp = ls_tbl-(<lv_f1>).
 lv_pt = ls_tbl-(<lv_f2>).
Unfortunatly I get the following error message:
<<The data object "LS_TBL" does not have a component called "".>>
I really do not understand why ABAP is trying to interpret the field symbol name as a string. Does anybody have a clue how to access the field of ls_tbl with the help of a field symbol?
Many thanks!!!

Hi ,
Please check the below sample code .
data : begin of st_table,
 myfiledname type c value '1',
 myfiledname1 type c value '2',
 end of st_table .
data : lv_filedname(11) type c value 'MYFILEDNAME'
filed-symbols : <fs> type any,
 <fs_table> type any.
assign st_table to <fs_table>.
Assign lv_filedname to <fs> .
assign component <fs> of structure <fs_table> to lv_pp.

You've asked a lot of questions the last few days. I think its time you do some reading. The Swing tutorial titled "Creating a GUI Using JFC/Swing: has sections on every component and example code of how to use them. You can even download the entire tutorial and all the example from the following link:
http://java.sun.com/docs/books/tutorial/
Here's the link specific link to the section on "Using Lists"

How to copy the same address for multiple contacts in Address Book?

Hi! I got a question, I didn't find an answer for yet.
How to copy the post address from one contact to another, without manual entering. I mean if I have one contact with already entered post address, can I just copy it someway at once to another contact?
I don't want cards to merge, I need separate contacts, that may have different phones, e-mails, but the same post address. Please, advise.

Thanks! yes, this is a solution I'm following now. But I was wondering about the similar way as it is made in Daylite or Contactizer - you create company with name and post address first, and then can create a contact for that company. And company name and post address will appear in contact name.
I just wonder why such a simple and useful solution isn't available in Address Book as default.
I know there are many scripts written for Address Book. Maybe there is something for this purpose?
