Internal table declaration -OO ABAP

Hi,
          I am looking to declare an internal table using OO objects. My declaration are as follows..
TYPES : Begin of itab,
                     f1 type c,
                     f2 type c,
             End of itab.
DATA : itab1 type standard table of itab.
DATA: wa_tab type itab.
I have an internal table to say itab_pa2001 which i am reading all the records of pernr into ITAB_PA2001.To get the text i want to select * from t5*** into ..... Finally wht am looking is to move some of the fields into the final table ITAB. Could you please let me know how to set this up as i am getting wrong values when i am looping as below.
how to declare a structure in ITAB using ABAP OO....??
LOOP at ITAB_PA2001 into wa_itab.
ENDLOOP.
Thanks,
Vind

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.

Use Internal table in WebDynpro ABAP.

Hi,
I am using a internal table, for calling a FM, which require Internal table as its parameter. Since Internal table with header line is not supported in ABAP OO. How to attain this.
Thanq For Ur time.
Cheers,
Sam

Hi Sam,
If we want to use an internal table for the FM as input then we can declare a table and use it.
But when we want use it as a workarea we need to define a work area (another attribute) of a internal table saparatly and use it.
Best regards,
Suresh

How to upload XML file into the internal table in Webdynpro ABAP ?

Hi Friends,
I am not able to upload the XML file into ABAP,can you please help me in solving this issue with the help of source code.
Regards
Dinesh

Hi Dinesh,
Try go through this program which I had developed earlier. It takes as input an XML file and then breaks it down into name-value pairs of an intrnal table. You need to pass an XML file as input to this program. (I had hard coded the path for my XML file in it. You need to replace it with 1 of your own or you can just delete it and use the browse button to selet the file on your PC)

XML to internal table conversion within ABAP mapping class

I am doing a ABAP mapping for file to Idoc. My requirement is to convert XML file into ABAP internal table (within ABAP mapping class). Is there any standard FM, method, transformation etc, which can be used here.

TSV_TNEW_PAGE_ALLOC_FAILED with internal table declared with occurs 0

HI guys,
when the internal table is declared as occurs 0, the dump TSV_TNEW_PAGE_ALLOC_FAILED is encountered, when changing the declaration into standard table, th dump disappears. Why is this so?
Thanks!

There are three type of tables: Standard, sorted and hashed tables (see [here|http://help.sap.com/abapdocu_70/en/ABAPDATA_ITAB.htm]). When you define a table using the keyword OCCURS you're still defining a standard table.
Your exception indicates that you're running out of memory. The difference in the declarations that you mention shouldn't cause that. Main difference between the two declaration versions is probably that your table defined via OCCURS has a header line, whereas your other table doesn't (unless you declared it explicitly as WITH HEADER LINE).
I don't think though that with that little information anybody could explain the short dump. Actually it sounds rather odd that the change you mention should cause the dump (or make it go away). So I suspect you probably have to post further details. You might want to check the shortdump yourself and place a breakpoint at this place and run it for each version. Maybe you can see some difference...

Accessing internal table declared outside of BAdI implementation

I am working on a BAdI implementation and within the BAdI, I need to manipulate the data of an internal table that is declared in the calling routine. This internal table is not a parameter to the BAdI call. I am wondering is there a way to access the internal table that is not recognized by the BAdI implementation? If so, what's the syntax to do this?
I know in debug mode, I am able to access the content of the internal table by using (Program)Itab. But I get a syntax error when accessing the internal table using (Program)Itab syntax.
Any help is appreciated!

Thanks, Max.
I tried your method, but I am getting a short dump due to type conflict. I think it's because the internal table I'd like to access is declared using the following syntax:
data: begin of itab occurs 0,
end of itab.
Therefore, when processing the assign statement, the field-symbol is being treated as a structure...
I tried to change the field-symbol type to any, but after that, I can't modify the table content using loop at type of syntax..
Do you have any other suggestions?
Thanks very much!

How to avaoid tables declaration in abap object 's

But my qsn is i am using select single * from dbtable in at selection-screen for validation, in that situation in that situation how to avoid table declaration, i tried with select single * dbtable into wa , but still its asking table declaration.
Pls help me out, thanks.

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 !

How to populate internal table( varaible of ABAP table type) in Excel VBA?

Hi,
I am trying to update a database table from excel using a VBA Macro.
I am able to connect to SAP and able to read data from SAP using a RFC. Similarly after updating certain values, i want to update a table in SAP.
Below are the steps I am doing apart from basic settings.
Getting the reference of the SAP TABLE type from RFC fucntion module
' Call RFC
Set MyFunc = R3.Add("UPDATE_TVARVC_VIA_RFC")
' Get reference and Values TVARVC
Set oParam4 = MyFunc.Tables("TVARVC")
   2. Loop over the active cells and populate oParam4
          " add values as below
    oParam4.Rows.Add
    oParam4.Value(1, "NAME") = ..................
    oParam4.Value(1, "TYPE") = ..................
    oParam4.Value(1, "NUMB") = ..................
Do it for all columns in the table line.
My query is how to identify active cells and make the above code dynamic in step 2.
Thanks in Advance,
Best,
Aneel

Hi Aneel,
You can try the following:
e.g.
for j = 1 to ActiveCell.SpecialCells(11).Column
oParam4.Rows.Add
if j=1 then oParam4.Value(j, "NAME") = ActiveSheet.Cells(1,j).Value
if j=2 then oParam4.Value(j, "TYPE") = ActiveSheet.Cells(1,j).Value
if j=3 then oParam4.Value(j, "NUMB") = ActiveSheet.Cells(1,j).Value
next j
