Internal table modification in ABAP object event

Hi Gurus
I have an internal table displayed using ALV - OOPS concept. THe internal table has 15 rows in my test program but it can go up depending on user inpout.
I am able to display it . on the screen . One of the fields is editable . It is required that it take input from user and on pressing enter , the value entered in that cell should be subtracted from a total amout displayed in the cell next to it.
I have used the following code . There are no errors , but nothing happens when I edit it. The screen remains as it is.
Any help will be very useful
DATA : ITAB type ITABT occurs 0.
DATA : itab_w like line of itab.

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 !

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.

To know the functionality of table control in ABAP Objects

Hi,
Is there any technique to achieve the functionality of table conrol in ABAP Objects?
Thanks.

Hello Raja
If you are using an editable ALV grid then you have the functionality of a table control and much much more.
ABAP-OO based ALV grids are much more powerful (and easier) than simple table controls.

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)

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

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.

my internal table data contains as displayed output only.
so i need to do operations at internal table level to get the required output.
thanks,

Edited by: padmaja vaddi on Mar 9, 2009 5:09 AM

Hi Padmaja,
Please see the code below:
itab1[ ] = itab[ ].
sort itab1 comparing date name.
delete adjacent duplicates from itab1.-->itab1 will contain 3 records and itab will contain 5 records
loop at itab1 into wa_itab1.
clear: wa_itab2, wa_itab.
loop at itab into wa_itab where date = wa_itab1-date
                                 name = ' '.
if wa_itab-state is not initial.
wa_itab2-state = wa_itab-state.
endif.
if wa_itab-country is not initial.
wa_itab2-country = wa_itab-country.
endif.
endloop.
wa_itab2-name = wa_itab1-name.
wa_itab2-date = wa_itab1-date.
wa_itab2-sl_no = wa_itab1-sl_no.
append wa_itab2 to itab2.
endloop.
And in the internal table itab2 , u will have the required output.

Unicode error:a line of internal table and a data object are not mutually c

Hi Friends,
    This is the issue in upgradation from 4.6c to ECC6.0
    I have an internal table itab which has include structure say 'xyz' . In xyz there is a field of type int4 as third field. I have a field as l_line which is a string.
data : begin of itab occurs 0.
         include structure zxyz.
data: end of itab.
data: l_line type string.
In the program I am getting the unicode error as:
" A line of "itab" and "l_line" are not mutually convertible in unicode program." at he following line.
loop at itab into l_line.
endloop.
Thanks,
Ali.

Hi Narendran,
I did the same earlier, but the field l_line is again used in the another line as follows
IF l_line CS w_group.----
(1)
where     w_group         LIKE zstr-cctr_group.
here zstr-cctr_group is same as one of the fields of structure xyz.
in line 1 it is giving warning as
l_line is incompatible and it must be C,N,D,T or string.
Thanks,
Ali

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

Passing an internal table WITH HEADER LINE to abap object

Hi. In another thread, it was explained how to pass an internal table to an abap object method. Is it possible to pass an internal table that has a header line, and RETAIN the header line once the table has been passed?
My problem is, that I can pass the table, update it, but the read buffer is not populated when returning from the object's method. This is the result of being able to pass a STANDARD TABLE type, but not a STANDARD TABLE WITH HEADER LINE.
This means that I have to read the table into a work area instead of doing a READ TABLE LKNA1 within the method, which is what I need to do.
Thanks.

Please check this sample program, notice that it is modifing the internal table and passing it back modified as well as passing the "work area" or "header line" back thru the exporting parameter.
