thanks in advance.
any helpful answer will be rewarded.
this is a urgent issue.
can any one pls code this and send to me.

Hi!
Do you mind using ALV list???
If you don't, try this code:

How to populate data in dynamic internal table

Hi Expert,
fyi. My dynamic internal table field is created base on data selected. Eg. select table qpcd has 5 records. These 5 recods will become fieldname to my dynamic internal table. My dynamic internal table will be
...itab
      01
      02
      03
      04
      05
The 5 records from qpcd is populated in another table call viqmel. I need to find the occurance of each code in viqmel and populate the number of occurance in itab in each of column. The final dynamic itab will be like this
table itab
01       02     03    04     05   -
> field name
2         0        1     0       1    -
> data

Logic for retreiving the values from a dynamic internal table

Hi all,
I have an issue with the logic to fetch data from a dynamic internal table into fields. let me give you guys an example the sy-tfill = 9 (subject to vary). I need to populate the fields.
Regards,
Sukumar

Hi,
this is for printing out the info in a dynamic table,
it will work likewise to insert data.
PARAMETERS:
p_tabnam TYPE tabname DEFAULT 'DB_TABLE_NAME'.
DATA:
lv_dref TYPE REF TO data,
ls_dd03l LIKE dd03l,
lt_fieldname TYPE TABLE OF fieldname,
ls_fieldname TYPE fieldname.
FIELD-SYMBOLS:
<fs> TYPE STANDARD TABLE,
<wa_comp> TYPE fieldname,
<wa_data> TYPE ANY,
<wa_field> TYPE ANY.
REFRESH lt_fieldname.
SELECT * FROM dd03l INTO ls_dd03l
                   WHERE as4local = 'A'
                     AND as4vers = '0000'
                     AND tabname = p_tabnam
                   ORDER BY position.
ls_fieldname = ls_dd03l-fieldname.
APPEND ls_fieldname TO lt_fieldname.
ENDSELECT.
IF NOT ( lt_fieldname[] IS INITIAL ).
CREATE DATA lv_dref TYPE TABLE OF (p_tabnam).
ASSIGN lv_dref->* TO <fs>.
SELECT * FROM (p_tabnam) INTO TABLE <fs>.
WRITE:
    / 'CONTENTS OF TABLE', p_tabnam.
LOOP AT <fs> ASSIGNING <wa_data>.
    SKIP.
    WRITE:
      / 'LINE', sy-tabix.
    ULINE.
    LOOP AT lt_fieldname ASSIGNING <wa_comp>.
      ASSIGN COMPONENT sy-tabix OF STRUCTURE <wa_data> TO <wa_field>.

How to delete data from dynamic internal table

Hi,
I have dynamic internal table and I have some slection screen fields , using these selection screen fields
(select -options), I have to filter the data? assigning will work with READ , but I have select options not the parametre,
and also delete will not work for dynamic table..
as we cannot use assigning with delete..
So how to do this?
and one more thing is , I cannot filter the data while selection( in select, I cannot filter the data-> as it's not coming directly from table, it's coming from buffer),
so now after selection of data, I need to filter the data from dynamic table.
Is there any way to do this?
Regards,
Mrunal

Hi matt,
I tried with below code as you said. But I am getting dump. can you help?
here is my piece of code.
FIELD-SYMBOLS: <LS_DATA> type any,
                           <LT_DATA> TYPE table,
                            <L_FIELD> type any.
    ASSIGN <l_buffer_entry>-dataptr->* TO <LS_DATA>.
    ASSIGN <l_buffer_entry>-dataptr->* TO <LT_DATA>.
LOOP AT <LT_DATA> ASSIGNING <LS_DATA>.
ASSIGN COMPONENT 'BUKRS' OF STRUCTURE <LS_DATA> TO <L_FIELD>.
IF <L_FIELD> NOT IN SO_BUKRS.
DELETE <LT_DATA>.
ENDIF.
UNASSIGN <L_FIELD>.
ASSIGN COMPONENT 'BELNR' OF STRUCTURE <LS_DATA> TO <L_FIELD>.
IF <L_FIELD> NOT IN SO_BELNR.
DELETE <LT_DATA>.
ENDIF.
UNASSIGN <L_FIELD>.
ENDLOOP.
and here is the description of my dump:->>>
You attempted to access an unassigned field symbol
(data segment 32772).
This error may occur for any of the following reasons:
- You address a typed field symbol before it is set using ASSIGN

that has been deleted
- You address a field symbol that had previously been reset using

- You address a global function interface parameter, even
though the relevant function module is not active,
that is it is not in the list of active calls. You can get the list

Column names of a dynamic internal table

Hi Friends,
I have a dynamic internal table flowing in my ABAP program and I want to list down the column names of the this dynamic internal table.
The declaration of this dynamic internal table :
   FIELD-SYMBOLS:
    <l_t_data>         TYPE STANDARD TABLE.
Can you please tell me how to get the column names?
Thanks,
Gaurav

Hi,
     You can use ABAP Runtime Type Identification to get the column names of the internal table.
e.g >
>lo_itab holds reference to description object of internal table whose column names i have to extract.
>Using method describe_by_data of class cl_abap_typedescr export the field symbol assigned to the table and import the object reference into lo_itab.
>Then using method get_table_line_type of lo_itab import line type description object reference into lo_line.
>Check if lo_line is referring to a structure, if yes , downcast it to a object reference lo_struct of type cl_abap_structdescr.
>The column description of all columns in the structure is stored in 'components' table of cl_abap_structdescr.
     So loop at the table to get all the column names stored in column 'name' of table 'components'.
Thank You.

How to use dynamic internal table when using gui_upload?

Hi Experts,
my scenario is like i have header data, item data and serial numbers.
so with respect to the quantity in unit of measure ,there will be number of serial numbers..
i have declared the dynamic internal table,but i am not getting the logic to change the structure accordingly with respect to the flat file entries..
is it possible to do or its not possible....any suggestion!!!!i have declared like this....
TYPES: BEGIN OF ty_final,
      bldat TYPE string,      "Document Date
      budat TYPE string,      "Psting Date
      bktxt TYPE string,      "Document Header Text
      werks TYPE string,      "Plant
      lgort TYPE string,      "Storage Location

      erfmg TYPE string,      "Quantity in Unit Of Entry
      anln1 TYPE string,      "Asset Number
      anln2 TYPE string,      "Asset Subnumber
      sernr TYPE string,      "serial Number
END OF ty_final.
DATA : it_final TYPE TABLE OF ty_final,
       wa_final TYPE ty_final.
FIELD-SYMBOLS : <fs_final> TYPE table.
ASSIGN it_final TO <fs_final>.
after this i called gui upload and passed internal table it_final..
but i have to change the internal table structure dynamically before the upload function.so that it will match with the flat file...
Regards
Karthick

There are at least two approaches you can use to change/generate new dynamic-structured table. Either with [RTTI + RTTS|https://wiki.sdn.sap.com/wiki/display/Snippets/CreatingFlatandComplexInternalTablesDynamicallyusingRTTI] or using [CL_ALV_TABLE_CREATE|http://www.sdn.sap.com/irj/scn/advancedsearch?query=cl_alv_table_create] . In this one just determine fieldcatalog of current table and change it accordingly, then regenarate table.
There are plenty of examples in SCN for this. You should not face difficulties applying this.

How to do parallel processing with dynamic internal table

Hi All,
I need to implement parallel processing that involves dynamically created internal tables. I tried doing so using RFC function modules (using starting new task and other such methods) but didn't get success this requires RFC enabled function modules and at the same time RFC enabled function modules do not allow generic data type (STANDARD TABLE) which is needed for passing dynamic internal tables. My exact requirement is as follows:
1. I've large chunk of data in two internal tables, one of them is formed dynamically and hence it's structure is not known at the time of coding.
2. This data has to be processed together to generate another internal table, whose structure is pre-defined. But this data processing is taking very long time as the number of records are close to a million.
3. I need to divide the dynamic internal table into (say) 1000 records each and pass to a function module and submit it to run in another task. Many such tasks will be executed in parallel.
4. The function module running in parallel can insert the processed data into a database table and the main program can access it from there.
Unfortunately, due to the limitation of not allowing generic data types in RFC, I'm unable to do this. Does anyone has any idea how to implement parallel processing using dynamic internal tables in these type of conditions.
Any help will be highly appreciated.
Thanks and regards,
Ashin

How to create Dynamic Internal table in ALV?

Hi all,
I have to create a ALV report based on dynamic internal table. The requirement is that when I enter the months in my selection screen I should get the data relevant to those many months only. For eg if in selection I have given January to March, I should get an ALV output with columns from January to March only.
Please help me with the coding part as I find it a bit confusing.
Please reply immediately.
Regards,
Bhavani.

Hi BHAVANI,
first you have to prapare a field catalog [(see this)|http://help.sap.com/saphelp_470/helpdata/en/52/5f060de02d11d2b47d006094192fe3/frameset.htm]
and than you can use a Method cl_alv_table_create=>create_dynamic_table
I hope that help a little.

How to transfer data from a dynamic internal table

Hi All
I want to transfer data from a dynamic internal table<dyn_table>
to a non dynamic internal table itab which should have the same structure as <dyn_table>.
How can this be done?
Regards,
Harshit Rungta

As stated earlier this can be done only through field symbols...
You cannot create an non dynamic internal table with ANY structure...using DATA statement
If the strucutre is defined well and good...you can create an non-dynamic internal table...
If you do not know the structure then the internal table has to be dynamic...and to be generated using field symbols
DATA: lv_ref TYPE REF TO data.
FIELD-SYMBOLS: <fs_dyn_table> TYPE STANDARD TABLE.
* You create a dynamic internal table...
CREATE DATA lv_ref LIKE (your_dynamic_internal_table).
ASSIGN lv_ref->* TO <fs_dyn_table>.
Now...do the transfer.
<fs_dyn_table> = "your_dynamic_internal_Table
Hope it helps!

Error while creating a dynamic internal table refers to custom field

Hi all,
I am getting the exception TYPE_NOT_FOUND when I try to create a dynamic internal table using:-
DATA: gr_desc TYPE REF TO cl_abap_typedescr.
gr_desc = cl_abap_typedescr=>describe_by_name( p_field ).
The field p_field is a Z-field inside a DB table, (e.g. a user added field in MARA). The statement fails at that point and gives a runtime exception. Any suggestions to how I may solve this problem? Or any alternatives for the same? I guess we face this issue for all custom fields..has SAP released a note for this??
Thanks..

that's just the wrong method, you should use DESCRIBE_BY_DATA
gr_desc = cl_abap_typedescr=>describe_by_data( p_field ).
Note: DESCRIBE_BY_NAME is to be used for referencing a DDIC type by its name. Example:
gr_desc = cl_abap_typedescr=>describe_by_name( 'MARA-ZZFIELD' ).

DYNAMIC INTERNAL TABLE CREATION BASED ON THE CONTENT OF ANOTHER INTERNAL TA

Hi All
I need to create an internal table at runtime.
I have a selection screen parameter which is specific to country, Which can take values below
eg:- IT_AREA for Italy(IT)
FR_AREA for France(FR)
IE_AREA for Ireland(IE).....And similary for other countries
Based on the Above parameter, I need to create Internal Table as below
DATA: itab TYPE italy_data Occurs 0.
If I declare as above, Then itab has fields from italy_data. And this internal table i will be sending it to Function Module to get data into it.
My Requirement is to Create the Internal table itab during runtime for tables italy_data OR france_data OR ireland_data based on selection screen parameter. Tables on Country may have different number of fields in it.
Can anyone help me on this??

At end of field, for dynamic internal table entries ?

Dear All,
I've data in my dynamic internal table.
But, to understand in a better way I created a test program with static entries.
Case 1 -->
DATA: BEGIN OF itab OCCURS 0,
        year TYPE char4,
        name TYPE char10,
      END OF itab.
DATA: BEGIN OF itab2 OCCURS 0 ,
        year TYPE char4,
        name TYPE char10,
        count TYPE i,
      END OF itab2.
DATA: gv_count TYPE i,
      gv_flag TYPE char1.
itab-name = 'AAAA'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'AAAB'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'AAAC'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'AAAD'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBB'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBA'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBC'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBD'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCC'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCA'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCB'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCD'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCE'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCf'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDD'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDA'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDB'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDC'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDE'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
SORT itab BY year.
LOOP AT itab.
* Counter
gv_count = gv_count + 1.
AT END OF year.
    itab2-count = gv_count.
    MOVE-CORRESPONDING itab TO itab2.
    APPEND itab2.
    CLEAR gv_count.
    WRITE:/ itab2-name,
    itab2-year,
    itab2-count.
    CLEAR itab2.
    CLEAR gv_flag.
ENDAT.
ENDLOOP.
Now for the above program the Output is :
Name     Year          Count
********** 2005          5
********** 2006          6
********** 2007          4
********** 2008          4
" Forget about the asterisk values as it's an example !
The above output is correct, But in my real case the table structure is not like the above .
The order of the field are in reverse.
i.e. The internal table is like this :
Case 2 -->
DATA: BEGIN OF itab OCCURS 0,
        name TYPE char10,
        year TYPE char4,
      END OF itab.
DATA: BEGIN OF itab2 OCCURS 0 ,
        name TYPE char10,
        year TYPE char4,
        count TYPE i,
      END OF itab2.
In this case if I'm using at end of year the output is coming wrong.
Even on change of is also not working.
Request you guys to help me out so that I can achieve the same output as of case 1 with the table declaration as of CASE 2.

Hello Rich Heilman,
Again you came for my rescue ............
My code for this scenario is like this :
DATA: BEGIN OF itab OCCURS 0,
        name TYPE char10,
        year TYPE char4,
      END OF itab.
DATA: BEGIN OF itab2 OCCURS 0 ,
        name TYPE char10,
        year TYPE char4,
        count TYPE i,
      END OF itab2.
DATA: gv_count TYPE i,
      gv_flag TYPE char1.
itab-name = 'AAAA'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'AAAB'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'AAAC'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'AAAD'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBB'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBA'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBC'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBD'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCC'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCA'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCB'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCD'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCE'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCf'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDD'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDA'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDB'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDC'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDE'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
SORT itab BY year.
LOOP AT itab.
* Counter
gv_count = gv_count + 1.
IF sy-tabix GT 1.
    ON CHANGE OF itab-year.
      itab2-count = gv_count.
      MOVE-CORRESPONDING itab TO itab2.
      APPEND itab2.
      CLEAR gv_count.
      WRITE:/ itab2-name,
      itab2-year,
      itab2-count.
      CLEAR itab2.
      CLEAR gv_flag.
    ENDON.
ENDIF.
ENDLOOP.
The Output is :
DDDC       2005          2
CCCf       2006          4
BBBD       2007          6
AAAD       2008          4
The above output is wrong.
Can u correct me where I'm doing wrong ?
