Dynamic Structures and Internal Tables

Hi All,
I am doing a report to create condition records based on the condition type and condition table. Assume the condition type as PR00 and it as condition table of 304,305,306.Each condition table as its own header and item fields.Based on the condition table that the user specifies in the selection screen
the header and item structures of my report should change dynamically and these should be moved to the dynamic internal table that contains both header and item fields.Can anyone give an idea how to achieve it. Thanks in advance.
Regards,
Chakradhar.

Hi All,
Thanks for your replies.
SPLIT i_string_line-input_str AT cl_abap_char_utilities=>horizontal_tab
INTO i_header_line-header
          i_header_line-vkorg
          i_header_line-vtweg
          i_header_line-pltyp
         i_header_line-waerk.
In the above syntax based on the condition table I selected on selection screen my flat file is as below.
case 1: If condition table given is 304
H    SalesOrganization    DistributionChannel    Customer
I    Material    Releasestatus    Amount    Currency    ValidFrom    ValidTo
case 2: If condition table given is 305
H    SalesOrganization    DistributionChannel
I    Material    Releasestatus    Amount    Currency    ValidFrom    ValidTo
case 3: If condition table given is 306
H    SalesOrganization    DistributionChannel     PriceListType     DocumentCurrency
I    Material    Releasestatus    Amount    Currency    ValidFrom    ValidTo
In the above code i_string_line-input_str contains the following heading of fields based on the condition table we select in selection screen.when I want to split them into respective fields
using INTO clause my structure should change dynamically.How can I achieve it and my entire program is in OOPS ALV.Thanks in Advance.

Chakradhar.

Structure and internal table

is it possible to made a report by using internal talbe and structure....if yes how and if u have sample code for that pls tell me....

Internal table declaration - work area and body

Hi all
I have declared my internal table in my program as
data : itab_wa type ZRESULT_LINE,
       itab    type ZRESULT_ROW.
Where ZRESULT_LINE and ZRESULT_ROW are the structure and table types.
Now I want to add
data: TCOLOR TYPE SLIS_T_SPECIALCOL_ALV.
in my internal table declaration. How can I do this. Please remember I need to have work area and body in my internal table as I have used work area and body in my code.
Waiting..............

Difference between the Field Group and Internal Table.

Hi all,
Can anybody tell me the difference between the Field group and Internal table and when they will used?
Thanks,
Sriram.

Hi
Internal Tables: They are used to store record type data in tabular form temporarily in ABAP programming. Or we can say, it stores multiple lines of records for temporary use in ABAP programming.
A field group is a user-defined grouping of characteristics and basic key figures from the EC-EIS or EC-BP field catalog.
Use
The field catalog contains the fields that are used in the aspects. As the number of fields grows, the field catalog becomes very large and unclear. To simplify maintenance of the aspects, you can group fields in a field group. You can group the fields as you wish, for example, by subject area or responsibility area. A field may be included in several field groups.
When maintaining the data structure of an aspect, you can select the field group that contains the relevant characteristics and basic key figures. This way you limit the number of fields offered.

String and Internal table

We have a large character string in the memory, e.g. of 5M.
(1) we want to split the character string into an internal table with a field of c(1000), for example.
(2) we want to read the internal table, and concatenate each line into one string.
For STRLEN and CONCATENATE, it always ignores the trailing blanks. However, we don't want to LOSE ANY BLANKS.
thanks,
-Stanley

I don't think there is any availble function module that does it. You may have to code for it. Also the blanks are a problem. So try something like this, which was actually suggested by Sanjay while responding to another question in this forum
First replace all the blank space with a character that you know for sure, will not be there in your string.
TRANSLATE mystring USING ' @'.
Now do your STRLEN and get your string length.
The you can split your string using the option INTO TABLE. Your itab will have only one field of 1000 length.
Then read the internal table and concatenate them back into the long string.
Finally, you reverse the pattern in the previous TRANSLATE statement to '@ '.

Field-symbols and internal table

Hello,
How do I declare a field-symbol as an intenal table?
I have a internal table declared, but i need to declare a field symbols as my internal table´s type. How do I do it?
What I wrote was this:
DATA: BEGIN OF IT_INTE OCCURS 0,
           FIELD(3) TYPE C,
       END OF IT_INTE.
FIELD-SYMBOLS: isn´t defined as an internal table, how do I fix it.
Thanks!!!
Gabriel.

It is very much possible to have a field symbol point to a internal table. Here is some sample code.
report zrich_0001.
data: begin of itab1 occurs 0,
      fld1(10) type c,
      fld3(10) type c,
      fld5(10) type c,
      end of itab1.
data: wa1 like line of itab1.
field-symbols: <fs_table> type table.
field-symbols: <fs_wa>.
field-SYMBOLS: <fs_field>.
* Setup the data
itab1-fld1 = '0000000001'.
itab1-fld3 = '0000000002'.
itab1-fld5 = '0000000003'.
append itab1.
itab1-fld1 = '0000000004'.
itab1-fld3 = '0000000005'.
itab1-fld5 = '0000000006'.
append itab1.
assign itab1[] to <fs_table>.
assign wa1     to <fs_wa>.
loop at <fs_table> into <fs_wa>.
* Write out each field of the line
do.
       assign COMPONENT sy-index of structure <fs_wa> to <fs_field>.
    if sy-subrc <> 0.
      exit.
      endif.
      write:/ <fs_field>.
enddo.
skip 2.
endloop.

Passing SELECT-OPTIONS and Internal Tables to SUBROUTINES

Hi Guys
In the code below my colleague has created her own table types in order to pass a select option and internal tables to her subroutine. Is there an easier way of making them known to the subroutine.
data : v_vbeln type vbeln_vf,
      it_bdoc type table of vbrp,
      it_t006 type table of t006a,
      wa_bdoc type vbrp,
      wa_t006 type t006a,
      it_bdoc2 type table of zsswathi_st_vbeln,
      wa_bdoc2 type zsswathi_st_vbeln
select-options s_vbeln for v_vbeln matchcode object zswathi_vbeln obligatory.
start-of-selection.
perform bdoc using s_vbeln[]
             changing it_bdoc
                      it_bdoc2
                      it_t006.
loop at it_bdoc2 into wa_bdoc2.
form bdoc using f_s_vbeln type ZSWATHI_ST_SELECT_OPTION_TA_TY       " all these are table types. for select options, a structure is created and then a table type for it is created.
        changing f_it_bdoc type zswathi_vbrp_ty_ta
                 f_it_bdoc2 type zswathi_vbeln_ty_ta
                  f_it_t006 type ZSWATHI_T006_TA_TY.
select * from vbrp into table f_it_bdoc where vbeln in f_s_vbeln.
      if f_it_bdoc is not initial.
      select vbeln sum( netwr ) prsdt from vbrp into table f_it_bdoc2 where vbeln in f_s_vbeln group by vbeln prsdt.
      sort f_it_bdoc2 by vbeln.
      "select * from t006a into table it_t006 for all entries in it_bdoc where msehi = it_bdoc-vrkme.
      select * from t006a into table f_it_t006 for all entries in f_it_bdoc where msehi = f_it_bdoc-vrkme.
   endif.
    endform.

Hi Brett,
1. you can use a select-options-range in a FORM subroutine also without passing it as a parameter because parameters and select-option range tables are global fields in their program.
2. If you need a parameter, declare it as type table or type standard table or type any table. You do not need any special table type.

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.

I wish I could help you.

Difference between line type and internal table?

Hi..
I wanted to know, what is the difference between Line type and Internal Table?

Hi,
Before the 4.7 release in SAP if we want to define an internal table we have to write the defination using the occurs statement and we need to define all the fields using INCLUDE STRUCTURE or indidually all the fields ine by one.
From 4.7 release of R/3 SAP introduced the Line type concept and it's part of the ABAP OOPS concept. for internal table defination we don't need to use the occur statements. Instead INCLUDE structure we need to create a Line type for that structure in Se11 and then we can define the internal table like :
DATA : ITAB TYPE TABLE OF <LINE_TYPE>.
Only thing is this table will be a table without header. So for internal table processing we need to define a work area structure of type line of line type . EX:
DATA: WA_ITAB TYPE LINE OF <LINE_TYPE>.
Hope this helps.
Thanks,
Greetson

Table types and internal table

You can INCLUDE TYPE.
Types: begin of itab,
       field1 type string,
       field2 type string,
*      More Fields in here.
       Field30 type string,
       End of itab.

String operations in internal table

Dear friends..
        Good morning.
                    I wish to know.. how i segregate the field from a database table to internal table into two different internal table field. say for example.
i have db table tab1 which has field number
tab1 -> number
and i have another internal table itab1 whic has two fields numa and numb
tab1 -> numa
     -> numb
i have value in tab1->number is 001 and 0001
i wish to segregate this two values in to internal table
if the value is 001 then it should be into 001 -> numa
if the value is 0001 then it should be into 0001-> numb
i dont know how to perform the string operations in internal table.. would you like to tell me how i fix this problem any suggetion, article, code will be great help of mine..
thanking you
Regards
Naim

Hi,
what u can do is check the lenth
lit_data_tab.
lit_data_3
lit_data_4.
lv_char3 type char3.
lv_char4 type char4.
lv_length type i.
loop at lit_data_tab.
lv_length = STRLEN ( lit_data_tab-value ).
if lv_length = 3.
   lv_char3 = lit_data_tab-value .
   append lv_char3 to lv_char3 type char3.
else.
   lv_char4 = lit_data_tab-value .
   append lv_char4 to lv_char3 type char4.
endif.
endloop.
if u want
numa numb
003   0003.
then u have to loop in one table and modify other.
that is any one table should contains both the field.
read the table with one field
mark helpfull answers

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.
