Define internal table depending on parameter

Hello,
does anybody know how internal tables can be defined when tablename is passed as parameter ?
I have p_table and want to define an internal table depending on its value (e.g. KNA1, MARA, LFA1 ) dynamically, so for example if p_table= MARA
DATA:
l_tab_table TYPE STANDARD TABLE OF MARA.
l_str_table TYPE MARA.
Has anybody done this before ?
Thank you!

Hi
U have to use field-symbols:
PARAMETERS: P_TABLE(30).
DATA: DYN_TAB TYPE REF TO DATA.
FIELD-SYMBOLS: <TAB> TYPE TABLE.
CREATE DATA DYN_TAB TYPE TABLE OF (P_TABLE).
ASSIGN DYN_TAB->* TO <TAB>.
I believe the option CREATE DATA ... TYPE TABLE is available from release 4.7.
If you use a lower release you have to use the method
CREATE_DYNAMIC_TABLE of class CL_ALV_TABLE_CREATE:
CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
EXPORTING
 I_STRUCTURE_NAME = P_TABLE
CHANGING
 CT_FIELDCAT = GT_FIELDCAT.
call method cl_alv_table_create=>create_dynamic_table
 exporting it_fieldcatalog = gt_fieldcat
 importing ep_table = DYN_TAB.
ASSIGN DYN_TAB->* TO <TAB>.
Max

How to use internal table in Exporting Parameter of method.

Hi Friends,
I am new to abap oops and using the following code to read a select-option and pass the data in an internal table but on defining
internal table of a standard type it is giving me following error :
ITAB is not an internal table - the OCCURS n specification is missing.
code
====
class lcl_get_details DEFINITION.
    PUBLIC SECTION.
      types : r_carrid type RANGE OF sflight-carrid.
      data : itab type STANDARD TABLE OF sflight.
      METHODS : get_data IMPORTING s_carrid type R_carrid
                         EXPORTING itab type sflight.
ENDCLASS.
class lcl_get_details IMPLEMENTATION.
METHOD get_data.
    select *
    from sflight
    into table itab
    where carrid in s_carrid.
    if sy-subrc eq 0.
      sort itab by carrid.
    endif.
endmethod.
ERROR : ITAB is not an internal table - the OCCURS n specification is missing.
Kindly help.

Hi,
I think your problem is, because you use 2 variables named ITAB in method get_data.
Instance-variable ITAB is defined as STANDARD TABLE OF sflight.
Exporting-parameter ITAB is defined as sflight.
It seems like in implementation of get_data exporting-parameter ITAB is used.
Try this implementation:
METHOD get_data.
select * from sflight into table me->itab
   where carrid in s_carrid.
if sy-subrc eq 0.
sort me->itab by carrid.
endif.
ENDMETHOD.
This should solve your compiler error.
Nether the less, get_data will yield an empty structure as result.

How to define internal table in smartform(urgent)

Hi all,
How can i define a internal table with header line in global data ???
i defined like
In Types,
TYPES : BEGIN OF T_XVBPLP2 ,
 VENUM(10),
 VEPOS(10),
 POSNR(6),
 VEMNG LIKE LIPS-LFIMG,
 MATNR LIKE LIPS-MATNR,
 CHARG LIKE LIPS-CHARG,
 ARKTX LIKE LIPS-ARKTX,
 END OF T_XVBPLP2.
TYPES: T_XVBPLP TYPE TABLE OF T_XVBPLP2.
In Global Data,
T_XVBPLP TYPE T_XVBPLP.
Still, i am getting error message that, Internal table is not with header line.
can u plz give me some examples , to define internal table with header line in smartform ???
any correct answers will be rewarded??
Regards
pabitra

Hi
define WA_ITAB in Global variables
variable name type assin associated type
t_text like zstc_text
you cannot define a internal table with header line in SMART Forms. Declare a internal table and a work area separately both referring to the same structure.
Then you can use the work area. So, in this case WA_ITAB is declared as a global variable of TYPE ZSTC_TEXT.

How to Define Internal Table in Smartform

Hello,
I have some problem on define Internal Table in Smartform
I define a Temp_IT_Gen Type LBBIL_IT_GEN in Global Definiations
but i find that it is not available for me to append data into it,
the error message is Temp_IT_Gen is not a Internal Table - the Occurs n Specification is missing
so how can i solve it?
i want to use the internal table in the hold program.
Thanks a lot in advance.

Hi,
First U define the Table type in 'TYPES' tab of Global Definitions and then assing that table type to Internal table in 'Global Data' tab.
Eg:
define the Table Type like below in TYPES tab.
TYPES:BEGIN OF ty_TEMP.
        INCLUDE STRUCTURE XXXXXXX.
TYPES:END OF ty_TEMP.
TYPES: g_t_temp TYPE STANDARD TABLE OF ty_TEMP .
Now, define the Internal table in Global Data tab like below:
Variable Name    Type assignment    Associated Type
G_T_ITEM_1       TYPE                    G_T_TEMP
NOTE: whatever U define in Global Definitions can be used only in SMARTFORM, if u want to use it in Program U must define in Form Interface.
Hope it helps!!

Defining internal table dynamcially...

Hello Gurus,
Currently I am defining internal table as follows. The custom table name is ZCUST.
data: itab LIKE ZCUST OCCURS 1 WITH HEADER LINE.
But I have a situation where I have to define a internal table dynamcially based on the
table name defined in configuration table.
How can I define itab dynamically where custom table name will be selected at runtime ?

(internal) Tables obsolete as parameter in function modules,

Hi
As you probably can see by the question, my ABAP Knowledge isn't exactly overwhelming !
anyway:
I'm trying to create a function module in NW2004s, This functionmodule should take an internal table, based on a structure as (import) parameter.
In the earlier version, I've done this by defining it under the TAB 'Tables' in the function builder - But know its telling me that "Tables Parameters are obsolete", and that I should define it under "Changing" instead.
I have tried that, but I'm only allowed to pass a single line, and if I try to do a Loop, in the function module, it tells me that ity isn't created as an internal table.
So please - what is the "best practice" here ?
Regards
Morten Nielsen

Hi All,
I followed Steps 1 and 2 but when I use the following select statement I get a dump with the error enclosed.
Step1. Created a structure ZDFKKCOHI which is a replica of DFKKCOHI.
Step2. Created a table type ZDFKKCOHITABLE with line type as ZDFKKCOHI.
Step3. In my function module I have a changing parameter ZDFKKCOHIPARAM of type ZDFKKCOHITABLE.
Step 4. When I use the following select clause I am getting a dump.
DATA: wa_zdfkkcohi LIKE LINE OF zdfkkcohiparam.
SELECT *
FROM dfkkcohi
INTO CORRESPONDING FIELDS OF TABLE zdfkkcohiparam
WHERE cotyp EQ zcotyp
AND gpart EQ zgpart
AND corr_status EQ zcorr_status.
LOOP AT zdfkkcohiparam INTO wa_zdfkkcohi.
*Move IT_ZDFKKCOHI to ZDFKKCOHIOUT.
*Append ZDFKKCOHIOUT.
*Clear IT_ZDFKKCOHI.
ENDLOOP.
What could be wrong?
Thanks for all your help in advance.

Returning Internal Table as Returning Parameter of Method (by Value).

When you return an internal table as the returning parameter of a method, it is passed by value. I understand the concept of passing by value vs. passing by reference, but exactly what this means in this case is ambiguous.
1) It could mean that the entire table, including data, is copied from the local table in the method into the parameter provided by the calling code.
2) Alternatively, it could mean that only the pointer to the table is passed by value and the data is not literally copied from one place in memory to another. This would not be the same as passing by reference. For instance, I believe this is how object references are passed by value.
I want to know how it works, so that I know if there is an efficiency problem with returning a huge table. The returning parameter is wonderful for getter methods, and I prefer to use it over exporting parameters, but I have some concern about passing tables as returning parameters since I don't know how this works.
Can anyone either explain this, or at least make it clear to me whether or not there is an efficiency issue?
Thanks, in advance,
-Chris

Thanks to those who tried to help me with this question, but I finally had to just figure it out on my own. I just realized today that there is a way to find the answer using the debugger's Go To->Status Display->Memory Use option. This shows how variables are stored in memory.
The answer:
First of all, if you set one internal table equal to another like:
i_tab1 = i_tab2.
or like:
i_tab1[] = i_tab2[].
both will simply set i_tab1 to point to the same memory that i_tab2 is using. It does not make a copy. Now, if you attempt to change i_tab1, with an append statement for instance, a copy of i_tab2's memory is made then! The requested change to i_tab1 is then applied to the copied data. AHA!!! This means that even if you think you are copying a table, you are not really doing it until it becomes necessary due to a divergence in values.
I specifically tested a returning parameter to see how memory is handled, and it is basically just like an '=' statment. No copy of the data is performed at first. The memory that is allocated for the local variable in the method is simply pointed to by the variable used in the calling code to recieve that value.
What if you then change the value in the calling code after the method has finished executing? The answer depends on the situation. If the value that you returned from the method is still being pointed to by another variable somewhere, then a copy is made when you attempt to change the returned table in the calling code, but if there is no longer another variable pointing to this memory, you can change the table in the calling program all you want without causing a copy in memory.
For instance, if you have a getter method that returns the value of an attribute, at first no copy will be made, but when you try to change the table in your calling code, a copy will be made then. However, if you just fill a local table in your getter method and return that table, there will never be a copy made, because the local variable that originally pointed to that memory expired when the method completed. That means that after the method completes, the only variable pointing to the allocated memory is the one in the calling code that recieved the returning value.
This is fantastic!! This behaives in a way that seems to provide maximum efficiency in most cases. Also, the table copies are never a waste, since they only happen upon changing of one of the table variables that point to the common memory, and in this case you would want to make a copy to avoid corrupting the other variable.
Also, even if you did return your table as an exporting parameter by reference, you would not gain any significant efficiency. There would still be no table copy if you don't change the returned table. Also, if you did change the returned table, you would still produce a table copy if there was another variable, like an attribute, still pointing to the memory that you set your exporting paramter from before.
The only situation that I can see resulting in a needless efficiency problem is if someone used a getter method to return the value of a table attribute, then changed the returned table in the calling program, and then used a setter method to set the whole table attribute equal to the changed table. This would be a waste, so maybe this should be accomplished in another way.
In conclusion, there is essentially no reason to hesitate returning a whole internal table as a returning parameter from a method call, even though it is pass by value.
Kudos to the ABAP development team for their good design!

Passing a program defined internal table to an abap object

Hi. I have an internal table that was previously defined and created by SAP that I need to process in a user exit. The table is defined exactly as shown below.
Is it possible to pass a table that was defined in this manner (not in the ABAP dictionary) as an argument to a method of an ABAP object?
If so, what would the data type of the itab parameter have to be when defining the object's method parameter list? Is it necessary to somehow "cast it" to the KNA1 table type once I receive the table into the method? If so, what is the data type of the object's receiving variable/attribute?
data: begin of lkna1 occurs 0001.
 include structure kna1 .
data:
 end of lkna1 .
Just as one additional piece of information, I am using version 4.5B and I am trying to do this through se24.
Thanks so much!

Hi again,
This kind of simple approach,
we can pass ANY KIND OF TABLE
WITHOUT HAVING TO DEFINE
LINE TYPE IN SE11.
1. doing this simply u will achieve what u want.
( i just tried the same)
2. in se24,
give like this
ITAB Importing Type STANDARD TABLE
3. in the calling program,
call like this,
report abc.
data: begin of lkna1 occurs 0001.
include structure kna1.
data: end of lkna1.
data: testobj type ref to zsdtest.
select * from kna1
into table lkna1.
lkna1-kunnr = '000234'.
create object testobj.
call method testobj->testreceive
exporting itab = lkna1[].
4.
then in the class, source code,
just use like this
(so that u can accesss the fields of the itab,
using myitab)
method TESTRECEIVE .
data : myitab type table of kna1.
myitab[] = itab[].
break-point.
endmethod.
5. thats all !

Error in passing internal table as returning parameter

Hi
Im new to ABAP OO.
I declared a parameter ret_kna1 Returning Type KNA1.
Inside the method, I am retrieving data from table KNA1 into internal table and then I want return the interal table value.
But Im not able to assing the internal table for eg : code
method READ_CUSTOMER_LIST.
data: lt_kna1 type TABLE OF kna1,
      wa_kna1 LIKE LINE OF lt_kna1.
data: lv_kunnr type kna1-kunnr,
      lv_land1 type kna1-LAND1.
SELECT * FROM kna1
INTO TABLE lt_kna1
WHERE land1 eq lv_land1.
insert LINES OF lt_kna1 INTO TABLE ret_kna1.
endmethod.
when I try to activate the error says 'ret_kna1 is not an internal table "OCCURS n" specification is missing.
but I can not declare the internal table 'ret_kna1' once again in the code, as it already defined in the parameter as type KNA1.
please help me how to assign internal table values to the returing structur.

Are you passing it as an EXPORT parameter?
use and define it in the TABLES section of your function module as so:
*" IMPORTING
*"     VALUE(INCLUDE_X_LEVELS) TYPE CHAR1 OPTIONAL
*" TABLES
*"      I_SELECTED_OU STRUCTURE HRROOTOB
*"      I_SELECTED_EE STRUCTURE OBJEC
*"      E_VIP_EPM_DISTR STRUCTURE ZHR_VIP_EPM_DISTR
*"      E_RETURN STRUCTURE BAPIRET1
That way you can pass value in the table (if needed) and then pass the table with your values based on your own logic

How to count no of line present in internal table depending on condtion.

Hi,
I want to count no of line present in one internal table.
For example: I have an internal table with output tax line item
lwa_gt_alv-ty_auste_ep consider this internal table having 100 lines
depending on the condition copany code(BUKRS), Year(GJAHR), and Document number(BELNR).
I want to count the number of line present for above mentioned condition in internal table lwa_gt_alv-ty_auste_ep.
Kindly help as soon as possible.
Thanks and best regards,
Niteesh Rai

Hello
So, count into exist loop/endloop:
data: counter type i.
loop at itab.
* do anything here ...
if BUKRS = " condition for bukrs here
and GJAHR = " condition for gjahr here
and BELNR = " condition for belnr here
    counter = counter + 1.
endif.
* do anything here ...
endloop.
write counter.
Also you may to try other way:
data: counter type i.
data: itab1 like itab occurs 0.
itab1[] = itab[].
delete itab1 where BUKRS NE " condition for bukrs here
               and GJAHR NE " condition for gjahr here
               and BELNR NE " condition for belnr here
describe table itab1 lines counter.
write counter.

Define Internal table

Hi,
My requirement is like that i declare one internal table like:
TYPES: BEGIN OF wa_mathead,
        matkl TYPE matkl,     "Material Group
        mvgr1 TYPE mvgr1,     "Material Class
        matnr TYPE matnr,     "Material
end of wa_mathead.
now i want to declare another internal table say itab with some new fields and including wa_mathead structure.
how can i do that.
Amit.

INCLUDE STRUCTURE is not valid in all contexts and should be avoided.
Simply use the type you've defined in the definition of your table:
TYPES: BEGIN OF wa_mathead,
        matkl TYPE matkl, "Material Group
        mvgr1 TYPE mvgr1, "Material Class
        matnr TYPE matnr, "Material
      end of wa_mathead.
TYPES: BEGIN OF itab_rec_type,
         hdr TYPE wa_mathead,
         f1 TYPE blah,
You'll have to acess the header data of a record of your itab as wa-hdr-matkl.

Defining internal tables

Hi,
I'm somewhat lost in my code. I have to use all fields of a table in my development. I tried doing it as follows but I receive an error like my internal table is not defined.
data: begin of t_type.
include structure tablename.
data: end of t_type.
data: i_internaltable type standard table of t_type initial size 0.
Then I did the following which worked fine:
data: i_internaltable type standard table of tablename initial size 0.
But the problem now is that I have to use one field from another table. Normally it should be like
data: begin of t_type.
include structure tablename.
data field like table-field.
data: end of t_type.
I'm lost.... Plz help
Thx

Hi,
Declare as below:
structure Declaration.
types: begin of t_type.
include structure tablename.
types: field like table-field.
types: end of t_type.
Table Decalartion.
data: i_internaltable type standard table of t_type initial size 0.
*Work area.
data: w_type type t_type
Now this will work.
Revert back if any issues.

Can't we pass custom defined internal table in SMARTFORM Interface

Hi,
I have a scenario, that my internal table from the program is is not dictionary type, but combination of some fields. Can't I directly pass this table to my smartform.
Thank U 4 Ur time.
Cheers,
Sam

hi,
We can not pass the Internal tables to a Smartforms, you need to create the Structure and give the Structure in the Smartform, and declare the the internal table of that structure type and pass it
