Sort itab by using field symbol

All,
I have a field symbol that pointing to a field value in work area of an internal table i_sort ( For example work area that contains the field name having a value MATNR' ( this decides only at runtime) )
My requirement is i need to sort another table for example i_tab (structure same as records in i_sort) using this field symbol.
Any Info?

Hi,
Check the below report sorting table VBAP based on field VBELN dynamically.
Let me know if u need any clarification.
REPORT ZTEST1.
tables: dd03l.
field-symbols: <fs1> type any,
 <fs2> type any.
data:
 wa_1 type vbak,
 w_index type sy-index.
data:
itab like standard table of vbap,
ftab like standard table of dd03l.
select * from vbap into table itab
 up to 10 rows.
select single * from vbak into wa_1 where vbeln ne space.
assign wa_1-vbeln to : <fs1>,
 <fs2>.
do.
assign component sy-index of structure wa_1 to <fs1>.
if <fs1> = <fs2>.
 w_index = sy-index.
 exit.
endif.
enddo.
select *
from DD03L
into table ftab
where TABNAME eq 'VBAK'.
sort ftab by position.
read table ftab with key position = w_index into dd03l.
sort itab by (dd03l-FIELDNAME).
Thanks,

How to use field-symbols in MODIFY ... TRANSPORTING and SORT

Hi,
I need to increase the performance of an abap report using the field-symbols. More exactly the code is the following.
TYPES:
BEGIN OF itab_structure.
 INCLUDE STRUCTURE nameofstructure.
TYPES:
 RECNO LIKE sy-tabix,
END OF itab_structure.
DATA:
itab TYPE STANDARD TABLE OF itab_structure
 WITH HEADER LINE
 WITH NON-UNIQUE DEFAULT KEY INITIAL SIZE 0.
SORT itab ASCENDING BY f1.
LOOP AT itab WHERE f1 = '10'.
 itab-fn= value-n.
MODIFY itab
 TRANSPORTING fx fy fz ft
 WHERE f1 = c1_filed AND
 f2 = c2_field.
ENDLOOP.
I need your suggestions in this kind of conversion or solution.
SORT itab ASCENDING BY f1 (<-- I don't know if in this case the better performances should be obtained using field symbols and in which way)
FIELD-SYMBOLS: <fs_itab_line> TYPE LINE OF itab.
LOOP AT itab ASSIGNING <fs_itab_line> WHERE
<fs_itab_line>-f1 = '10'.
MODIFY itab
 TRANSPORTING fx fy fz ft
 WHERE f1 = c1_filed AND
 f2 = c2_field.
(I don't know if in this case the better performances should be obtained using field symbols and in which way)
ENDLOOP.
I wish to implement the field symbols or the better performance in terms of execution time in all my abap code, where it is possible.
Any suggestion will be well appreciated.
Thanks in advance for your kind support.
Regards,
 Giovanni

Dear All,
I have appeciated your suggestions and I can conclude these points in my case:
1) The "sort" statement is not optimized in a different way using filed-symbols
2) The loop with "where" condition on a standard table is performed using filed-symbols
But ... my last point to investigate is about the statement MODIFY table TRANSPORTING f1, f2 WHERE conditions.
More exactly, in my code the execution logic of the abap code expects a global modification of the same table at the end of every (primary) loop, using the MODYFY statement.
In other words in my code I can locate two loops on the same table in the following logic:
LOOP AT table1 WHERE f1 = '10'. (#1)
 updates to table1
 set c1_filed, c2_filed
 LOOP AT table1. (#2)
 IF f1 = c1_filed AND
 f2 = c2_filed.
 table1-fx = 'x'.
 table1-fy = 'y'.
 table1-fz = 'z'.
 table1-ft = 't'.
 ENDIF.
 MODIFY table1.
 ENDLOOP. (#2)
ENDLOOP. (#1)
In better way (maybe more fast in terms of execution time) to modify a set of lines (MODIFY...TRANSPORTING...WHERE):
LOOP AT table1 WHERE f1 = '10'.
 table1-fx= 'x'.
 table1-fy= 'y'.
 table1-fz= 'z'.
 table1-ft= 't'.
 MODIFY itab
 TRANSPORTING fx fy fz ft
 WHERE f1 = c1_filed AND
 f2 = c2_field.
ENDLOOP.
My aim is to use field-symbols everywhere possible for speeding up the execution of my code,by maintaining this logic.
My proposal should be the following but I need your kind opinion.
FIELD-SYMBOLS: <fs_#1_line> TYPE LINE OF table1.
FIELD-SYMBOLS: <fs_#2_line> TYPE LINE OF table1.
LOOP AT table1 WHERE f1 = '10' ASSIGNING <fs_#1_line>. (#1)
 updates to table1
 set c1_filed, c2_filed
 LOOP AT table1 ASSIGNING <fs_#2_line>. (#2)
 IF <fs_#2_line>-f1 = c1_filed AND
 <fs_#2_line>-f2 = c2_filed.
 <fs_#2_line>-fx = 'x'.
 <fs_#2_line>-fy = 'y'.
 <fs_#2_line>-fz = 'z'.
 <fs_#2_line>-ft = 't'.
 ENDIF.
 ENDLOOP. (#2)
ENDLOOP. (#1)
Your kind support is very important for me.
Thanks in advance.

Can I use field symbol in AT events? How?

Hi all,
I want to use field symbol in AT END OF event
Can I use field symbol in such event as it takes table fields only.
Kinldy look in to pseudo:
Loop itab.
 AT END OF <FS1>.
 ENDAT.
Endloop.
I tried in my program but it's giving me a short dump.
If it is possible to use field symbol in AT events, kindly tell me how..??
Thanks in Advance.

INSERT t2 t1 INTO header.
t1 ='AABB'. t2 = 1. EXTRACT header.
t1 ='BBCC'. t2 = 2. EXTRACT header.
t1 ='AAAA'. t2 = 2. EXTRACT header.
t1 ='AABB'. t2 = 1. EXTRACT header.

t1 ='AAAA'. t2 = 1. EXTRACT header.
t1 ='BBBB'. t2 = 1. EXTRACT header.
t1 ='AAAA'. t2 = 3. EXTRACT header.
t1 ='AABB'. t2 = 1. EXTRACT header.
SORT BY t1 t2.
*Here begins the definition of the field symbols
FIELD-SYMBOLS:

Delete row from internal table using field symbol.

Hi friends,
I created dynamic internal table using field symbol. I want to delete some data using where clause.
for example. i want to use like,
DELETE <FS> WHERE KUNNR = WA_KNA1-KUNNR.
Like the above statment it won't work. How i can use delete with where clause in field symbols.
Hope any one can help me.
Thanks and regards
Srikanth. S

hi Srikanth,
I think you have to LOOP through the whole internal table and check each line and decide to delete or not:
LOOP at <itab> INTO <wa>.
ASSIGN COMPONENT 'KUNNR' OF STRUCTURE <wa> TO <field>.
CHECK <field> IS ASSIGNED.
IF <field> EQ WA_KNA1-KUNNR.
DELETE ...
ENDIF.
UNASSIGN <field>.
ENDLOOP.
hope this helps

How to use FIELD-SYMBOLS to declare a table

How to use FIELD-SYMBOLS to declare a table?

hi yong,
this will be very general:
FIELD-SYMBOLS : <gf_table> TYPE ANY TABLE.
or
to do like a specific table from your program
FIELD-SYMBOLS : <gf_table> TYPE itab.
itab is of course your internal table from your program.

But, am getting the below error message in SLIN/Extended Prog Check.
Fieldsymbol <FS_DATA> is not assigned to a field
(The message can be hidden with "#EC *)
1) I do not understand why am getting this (if itab contains any data then ONLY the loop will be executed right?)
2) How to correct this?
Thank you

Hello,
Correct method of using a field-symbol is to assign it first with the structure.
You use INTO if working with work area. Example:
LOOP AT itab_data INTO w_data.
Use assigning keyword when using field-symbol in case of LOOP...ENDLOOP.
LOOP AT itab_data ASSIGNING <fs_data>.
Check below link on 'Assigning Data Objects to Field Symbols':

Using field-symbols with FOR ALL ENTRIES IN ...

Hi all of you,
Is it possible to use field symbol by the FOR ALL THE ENTRIES IN itab.
Normally, isn't possible.
So my problem is that I'm having duplicate code.
I've something like this.
 IF ap_objcl EQ omaterial.
 SELECT objectid
 INTO TABLE i_cdpos
 FROM cdpos
 FOR ALL ENTRIES IN otf_materials
 WHERE objectclas = ap_objcl AND
 tabname = otf_materials-tablename AND
 fname = otf_materials-fieldname.
 ELSEIF ap_objcl EQ otf_documents...
And I'm looking to use otf_materials and otf_documents
So, instead to duplicate the code, I'm looking for a way to restrain the code by using maybe field symbols.
Ideal :
FIELD-SYMBOLS : <otf_mats_docs> LIKE OTF_TABLE.
IF ap_objcl EQ omaterial
ASSIGN local copy of otf_materials TO <otf_mats_docs> CASTING.
ELSEIF ap_objcl EQ odocuments
ASSIGN local copy of otf_documents TO <otf_mats_docs> CASTING.
ENDIF.
 SELECT objectid
 INTO TABLE i_cdpos
 FROM cdpos
 FOR ALL ENTRIES IN <otf_mats_docs>
 WHERE objectclas = ap_objcl AND
 tabname = <otf_mats_docs>-tablename AND
 fname = <otf_mats_docs>-fieldname.
IF ap_objcl EQ omaterials.
*Do nothing
ELSEIF ap_objcl EQ odocuments.
*Do something with the date in otf_documents.
ENDIF.

Hi,
Ok, using forms is great things to deal with it.
But, may be it'll slow down the program and I need a really rapid program.
I tried using form.
The problem by pushing the FOR ALL ENTRIES IN <structure>
didn't works.
It tells me that the structure that I pushed via "using" is not an internal table.
The same structure work find in the global program.
What should I do ?.
The structure is given by as a parameters in Function Module.

How to populate one internal table from another using field symbols

Hi Gurus,
I have a problem. I have to populate one internal table (sructure t_otput) from another internal table (sructure t_from) using field symbol.
Structure for from table.
types: begin of t_from,
 year(4) type c,
 ww(2) type c,
 site type marc-werks,
 demand type i,
 end of t_from.
Structure for output table.
types: begin of t_display,
 title(30),
 WW1(10),
 WW2(10),
 WW3(10),
 end of t_display.
The from table looks like this:
Year | WW | Site | Demand
2005 | 1 | OR1 | 12.00
2005 | 2 | OR1 | 13.00
2005 | 3 | OR1 | 14.00
The display table which has to be populated should look like this:
Title | WW1 | WW2 | WW3
OR1 | | |
Demand | 12.00 | 13.00 | 14.00
How to populate display table using field symbol?
Please give code snippets

Hi,
I had similar requirement wherein I was supposed to display different data using 2 different internal tables on a subscreen area.
The screen consists of two parts: 1) selection-screen with few input fields and two buttons 2) Subscreen area where the report need to be displayed. This report is displayed based on the button that the user is selecting. For this I have done the following things:
1. Capture the sy-ucomm when user is clicking on any of the two buttons in PAI. Then perform data fetch operation.
 MODULE USER_COMMAND_9003 INPUT.
 CASE OK_CODE.
 WHEN 'DETAIL'.
 GV_RPT = OK_CODE.
 PERFORM F_GET_DETAIL_DATA.
 WHEN 'REPORT'.
 GV_RPT = OK_CODE.
 PERFORM F_GET_REPT_DATA.
 ENDCASE.
 ENDMODULE. " USER_COMMAND_9003 INPUT
2. Declare two different ALV's with the fieldcat similar to 2 internal tables respectively. Use the above sy-ucomm PBO to call appropriate ALV.
 MODULE DISPLAY_ALV OUTPUT.
 IF GV_RPT EQ 'DETAIL'.
 PERFORM F_FIELDCAT_DETAIL.
 PERFORM F_LAYOUT_DETAIL.
 PERFORM F_EXCLUDE_TOOLBAR_DETAIL.
 PERFORM F_DISPLAY_ALV_DETAIL.
 ELSEIF GV_RPT EQ 'REPORT'.
 PERFORM F_FIELDCAT_REPT.
 PERFORM F_LAYOUT_REPT.
 PERFORM F_EXCLUDE_TOOLBAR_REPT.
 PERFORM F_DISPLAY_ALV_REPT.
 ENDIF.
 ENDMODULE. " DISPLAY_ALV OUTPUT
3. Before displaying ALV you need to free the container and ALV.
FORM F_DISPLAY_ALV_DETAIL .
IF GC_CONTAINER_ES IS NOT INITIAL.

Problem in using Field Symbols in HIDE statement

Hi All,
I am working in an Upgrade project ( from 4.6B to ECC 5.0 ). In a program I found few warnings on HIDE statement because they have used Field Symbols in HIDE statement.
The warning is " HIDE on a field symbol is dangerous, but the formal parameter "" is not ".
and the piece of code is
SET EXTENDED CHECK OFF.
HIDE: flg_pick_up, <s1>, <s2>, <s3>, <s4>, <s5>, z_feld_ind.
CLEAR flg_pick_up.
SET EXTENDED CHECK ON.
all the field symbols are of type ANY. SO can any one help in removing those warnings.
Please reply me as soon as possible.
With Regards,
Amarnath Singanamala

Hi amarnath,
1. Why do u want to remove
the warning ?
2. This warning (and not an error)
is a GENUINE warning,
which the system wants the user to make aware of.
3. By doing some xyz,
even if u may be able to hide the warning,
the warning may be hidden (for display purpose only),
but,
the warning will still be there inside the system.
4. I think u should ignore the warning,
(if there are no other repurcussions).
regards,
amit m.

Going for dump while using field symbols

How to use field symbols

can anyone tell me how to use field symbols. What effect it has on performance of a program?
what r its avantages?
iam working on a report where iam facing a lot of problems in performance issue. can anyone tell how field symbols are useful in this regard?
thanx to all

Check the below links
http://help.sap.com/saphelp_nw04/helpdata/en/fc/eb3860358411d1829f0000e829fbfe/content.htm
FIELD-SYMBOLS
Basic form
FIELD-SYMBOLS <fs>.
Additions
1. ... STRUCTURE s DEFAULT wa
2. ... TYPE t
3. ... TYPE LINE OF t
4. ... LIKE s
5. ... LIKE LINE OF s
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN . All operations performed with the field symbol then directly affect the field assigned to it.
You can only use one of the additions.
Example
Output aircraft type from the table SFLIGHT using a field symbol:
FIELD-SYMBOLS <PT>.
TABLES SFLIGHT.
ASSIGN SFLIGHT-PLANETYPE TO <PT>.
WRITE <PT>.
Addition 1
... STRUCTURE s DEFAULT wa
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP/4 Dictionary ( s ). All fields of the structure can be addressed by name: <fs>-fieldname . The structured field symbol points initially to the work area wa specified after DEFAULT .
The work area wa must be at least as long as the structure s . If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.
Addition 2
... TYPE t
Addition 3
... TYPE LINE OF t
Addition 4
... LIKE s
Addition 5
... LIKE LINE OF s
Effect
You can use additions 2 to 5 to type field symbols in the same way as FORM parameters (see also Type assignment of subroutine parameters). ASSIGN performs the same type checks as with USING parameters of FORM s.
