Runtime FIELD DELETION / HIDING of Internal Table

Dear All,
Can Anybody would like to say " How can i delete a field of internal table before passing it the FIELD_CATALOGE_MERGE Function In ALV Report"
Or i wil be also thank ful to you if you would tell me " How can i hide the field of internal table at runtime In ALV Report"
Warm Regards,
Nirav Parekh

HI,
We do not have an option to delete a field from an internal table at runtime, we have an option to delete the data from it .
To hide a Field in ALV :
set wa_fieldcatalog-no_out = 'X'.
loop at t_fieldcatalog into wa_fieldcatalog.
if wa_fieldcatalog-fieldname = 'BOX'.
wa_fieldcatalog-no_out = 'X'.
modify t_fieldcatalog from wa_fieldcatalog.
ENDIF.
ENDLOOP.

Field description of an internal table

Hi,
I am trying to read the field description of an internal table, which consists of fields from different DD tables. I am able to read the descriptions of a DD table by using FM 'DDIF_FIELDINFO_GET'.
Can you please suggest me how can read the text descriptions of an internal table fields in a Language other than English.

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 Khan

Hi, 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.

Delete Command in Internal table

Hi Friends,
Currently i am using DELETE command in internal table. My main requirement is delete the records in internal table based on the select -options given in Selection screen.
Synatx is given below.
DELETE i_list WHERElifsk NOT in S_lifsk[].
It is working fine if we give positive values ie EQ 24 etc.
if we give negetive values if NE 23(in select options) here
sy-subrc is failing.
Can any one kindly suggest.
Regards,
DVNS.

Hi DV
Its so simple... u r requirement is to delete all the entries which are not in the select options.
Ur sintax is working correct. Because, even if u hit a database table with select querry using this select option, it will fetch all the positive entries and excludes all negative entries....
if still u feel problem is persisting... then fetch the lifsk from db table using this select option into an internal table and then filter how ever u want.

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,
Hardik

Anurag,
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
ASSIGN (T_KBETR) TO <FS> .
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

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.

Thank you.

Hi Rahul,
maybe thread dynamic program for alv is helpful for you. More information about the [SAP List Viewer (ALV)|http://help.sap.com/saphelp_nw70/helpdata/EN/5e/88d440e14f8431e10000000a1550b0/frameset.htm]. Also have a look into the example programs SALV_DEMO_TABLE*.

Data from field symbol into an internal table or workarea

Hi Experts,
I have field symbol in which i get the data. I want to get this data into an internal table of type any or into an work area. How is this possible.
My declaration for field symbol is as follow:
FIELD-SYMBOLS: <l_t_data> TYPE any.
DATA l_r_data TYPE REF TO data.
 CREATE DATA l_r_data type STANDARD TABLE OF (l_local_tab).
 ASSIGN l_r_data->* TO <l_t_data>.
I get the data in this field symbol <l_t_data>. by passing into a funtion module. and I get the data into it. Now i have to assign the values of this field symbol to any internal table or to a work are how do i do it. Please help.
Regards,
Prashant.

Not exactly sure what you need here, but.....
FIELD-SYMBOLS: <l_t_data> TYPE TABLE. "<<-- Change this
FIELD-SYMBOLS: <l_s_data> TYPE ANY. "<<---Add This
DATA l_r_data TYPE REF TO data.
CREATE DATA l_r_data type STANDARD TABLE OF (l_local_tab).
ASSIGN l_r_data->* TO <l_t_data>.
Loop at <l_t_data> assigning <l_s_data>.
* Do what ever using <l_s_data>
Endloop.

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

Delete Duplicates from internal table with object references

Hi
How can I delete duplicates from an internal table in ABAP OO based on the value of one of the attributes?
I have created a method, with the following code:
LOOP AT me->business_document_lines INTO l_add_line.
 CREATE OBJECT ot_line_owner
 EXPORTING
 i_user = l_add_line->add_line_data-line_owner
 i_busdoc = me->business_document_id.
 APPEND ot_line_owner TO e_line_owners.
ENDLOOP.
e_line_owners are defined as a table containing only object references.
One of the attribute of the object in the table is called USER. And I would like to do a "delete ADJACENT DUPLICATES FROM e_line_owners", based on that attribute.
How can do this?
Regards,
Morten Nielsen

Hello Morten
Assuming that the instance attribute is public you could try to use the following coding:
SORT e_line_owners BY table_line->user.
DELETE ADJACENT DUPLICATES FROM e_line_owners
 COMPARING table_line->user.
However, I am not really sure (cannot test myself) whether TABLE_LINE can be used together with SORT and DELETE.
Alternative solution:
DATA:
 ld_idx TYPE sy-tabix.
LOOP AT e_line_owners INTO ls_line.
 ld_idx = syst-tabix + 1.
 LOOP AT e_line_owners TRANSPORTING NO FIELDS FROM ld_idx
 WHERE ( table_line->user = ls_line->user ).
 DELETE e_line_owners INDEX syst-tabix.
 ENDLOOP.
ENDLOOP.
Regards
Uwe
