Hi Jagan,
Use the below code.
TYPE-POOLS: SYDES.
DATA: TD TYPE SYDES_DESC.
DATA: BEGIN OF WA OCCURS 0,
CONTINUE TYPE C,
NAME(15) TYPE C,
END OF WA.
TYPES:BEGIN OF STR1,
NUM(3) TYPE N,
NAME(20) TYPE C,
END OF STR1.
*DATA: ITAB LIKE T247 OCCURS 0 WITH HEADER LINE.
*DATA: ITAB TYPE STR1 OCCURS 0 WITH HEADER LINE.
DATA: BEGIN OF ITAB OCCURS 0,
NUM(3) TYPE N,
NAME(20) TYPE C,
END OF ITAB.
DESCRIBE FIELD ITAB INTO TD.
WA[] = TD-NAMES[].
LOOP AT WA.
IF WA-NAME = SY-REPID.
DELETE WA.
CONTINUE.
ENDIF.
SEARCH WA-NAME FOR '-'.
IF SY-SUBRC = 0.
DELETE WA.
CONTINUE.
ENDIF.
SEARCH WA-NAME FOR '='.
IF SY-SUBRC = 0.
DELETE WA.

Debugging ECC6: how to see the fields name when download internal table?
When we debug a reprot in ECC6 and save to a local file an internal table, the fields are not appearing only the data,
Is there a way to download also the table fields name?From the new debugger switch to the classic debugger using menu path Debugger->Switch to Classic Debugger. Form the classic debugger you can download internal table data with column name(s).

To read the column names of an internal table
Hi ,
I want to read the column/field names of an internal table into another internal table.
How can this be done?
Kind Regards,
hgarsht RungtaHi ,
you can get the attributes of any internal table into another ..
check the following code ..
DATA : it_mara TYPE STANDARD TABLE OF mara WITH HEADER LINE.
DATA : it_detail TYPE abap_compdescr_tab,
wa_comp TYPE abap_compdescr.
DATA : ref_descr TYPE REF TO cl_abap_structdescr.
ref_descr ?= cl_abap_typedescr=>describe_by_data( it_mara ).
it_detail[] = ref_descr->components .
loop at it_detail into wa_comp.
write:/ wa_comp-name .

How to add one more field to an exist internal table
hi abapers
i am a very new abap programmer and just started learning it.
i want to know How to add one more field to an exist internal table.
lemme me put my question in a very simple way.
i have a internal table having fields f1,f2,f3 and which also that internal also contains some data.
now i want to add two more fields (mm & nn) to that internal table now.
how can i do that.
and i wanna know the websites names where i can find some brain teasing questions in abap programming.
eagerly waiting for ur reply
regards,
Maqsood A KhanHi, MAQSOOD.
You can insert more fields in your internal table like this.
refer this code snippet.
DATA : BEGIN OF tbl_itab OCCURS 0.
INCLUDE STRUCTURE zsdtc009.
DATA : vkorg LIKE vbak-vkorg, "inserted one
vtweg LIKE vbak-vtweg, "inserted one
vkbur LIKE vbak-vkbur, "inserted one
vkgrp LIKE vbak-vkgrp, "inserted one
END OF tbl_itab.
you can also read the book "Teach yourself abap in 21 days"
at http://cma.zdnet.com/book/abap/
but that book is just about basic concept of abap and report program.
it doesn't give a lecture for on-line program.
you can get pdf version books(about abap, sap...things) from sap.
http://help.sap.com/printdocu/core/Print46c/en/Data/htm/english.htm
I wish I could help you.

I have extended your source code and just used vbak/vbap as an example as they have some common fields like vbeln/erdat etc which corresponds with your requirement of 'similar structure' i.e. shared/common fields in both.

Are field symbols and Dynamic internal tables consistant?
Hi,
Are field symbols and Dynamic internal tables
always consistent?
In my program I m creating a dynamic itab and assignig values to it using <FS>, sometimes the program fails to execute assign <Fs> statement...
this happens once in 3 to 4 runs
any solution...
I have proper clear and refresh statements in program.
Thanks,
HardikAnurag,
Thanks for a quick reply. Here I am sending a small piece of my code.
MOVE-CORRESPONDING OUTTAB TO DYNTAB.
CLEAR IT_UDATE.
CLEAR : T_KBETR .
READ TABLE IT_UDATE WITH KEY UDATE = OUTTAB-UDATE.
CONCATENATE 'DYNTAB-KBETR' IT_UDATE-CO_POS INTO T_KBETR.
ASSIGN (T_KBETR) TO <FS> .
SUBRC5 = SY-SUBRC .
IF SUBRC5 = 0 .
<FS> = OUTTAB-KBETR .
ENDIF .
read statement will always return CO_POS .
while debuging this code a few times
<b>ASSIGN (T_KBETR) TO <FS> .</b>
returns sy-subrc = 4
and that was leading the program to short dump earlier.
now, as I have a check DYNTAB-KBETR holds no value on display.
this happens very few times. (most of the times report is displaying desired output)
Thanks,
Hardik -

Rams.Dear All,
In need to pass tabular data i.e. multiple entries from field symbol to the table parameter of the custom function module.
Field symbol is declared as below:
FIELD-SYMBOLS: <FS_EXCEL_TAB> TYPE STANDARD TABLE,
<FS_TABLE_HEADER> .
DATA WA_PD LIKE PRICE_DOWNLOAD.
APPEND <FS_TABLE_HEADER> TO <FS_EXCEL_TAB>.
CLEAR <FS_TABLE_HEADER>.
WA_PD-VKORG = <FS_EXCEL_TAB>-VKORG.u201D Problem while using this statement
APPEND WA_PD TO PRICE_DOWNLOAD.
CLEAR WA_PD.
Field symbol <FS_EXCEL_TAB> is populated like this.
VKORG | KUNNR_SH | KUNNR_SP |

Here i will be knowing the fieldname. If i can get to know the column name i.e whether f1 or f2 or ... .i Can populate the data into the table control.
Wht i have done is taken a field symbol and used the following code.

How can I transfer the name "IT_TAB" into the field tabname?
Thanks in andvance!No, it has to by 'dynamic'. I don't want to transfer it hard, because it should work for any internal table name.
The requirement is: There are many function modules that have an input field TABLENAME. I have to give the tablename in the Form 'IT_TAB'.
But I look for a possibiltity not to write:
tabname = 'IT_TAB'.
For DDIC-Tables its not a problem, but I dont know a way for internal tables.
