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.

  • Dynamic internal table column issue

    Hi
    i have ALV report with dynamic internal table.after i build the internal table and fieldcatalog i have problem  i.e. when grid is displayed then one of the column value is coming in the next column.i populated col_pos in field catalog also and in the debug mode data is populated correctly for respective columns in fieldcatalog and dynamic internal table. But when it is displayed i have this problem.
    any inputs on this?

    Hi Moorthy,
    Did you perform an ALV consistency check?

  • Dynamic Internal Table with the same name

    Hey Guys
    I have a question.
    I know that we can create dynamic internal table taking a struct dynamically.
    But I have 2 ques on the same subject.
    1. Can we create an internal table based on a type that we have locally declared eg
    types: begin of ty_demo.
               var1(1) type c,
               var2     type p,
              end of ty_demo.
    2. If an internal table is already declared based on the above type say data: i_tab type standard table of ty_demo.
        If i need to enhance the struct of this internal table. Can i do that by dynamically redefining it based on a different structure but keepin the same name i_tab.
    In a nut shell I cannot change the name of my itab but I want to enhance the structure.
    I Hope I am clear.
    Help will be greatly apprcieated.
    Thanks
    Sameer

    hai.
    we can create an internal table based on a type that we have locally declared, but you have to use data instead of types like.
    data: begin of ty_demo.
    var1(1) type c,
    var2 type p,
    end of ty_demo.
    check the example notes for dynamic itab .

    If you really want to have a dynamic table, then you will have to find a way to generate a whole new table, and then copy the data from the old table to the new one. There is no way to modify a type during runtime in ABAP.

  • How to Organize the columns in the dynamic internal table?

    Hello Folks!
    How to Organize the columns in the dynamic internal table? i tried passing the parameter COL_POS to the fieldcatalog, Which is not working.

    Organize in What order ? What is your way to output ?
    If you use ALV, you need to create fresh FIELD CATALOG for your dynamic table and then assign the column position.

  • Creating Dynamic Internal table with a dynamic name

    Hi,
    I want to create dynamic internal tables with dynamic names.
    For example:
    Suppose I have a table with three fields.
    1. Structure name
    2.Fields
    3.file
    And the structure of the internal table is as follows:
    TYPES:BEGIN OF table_type,
          struct                  TYPE char70,
          fields                   TYPE tt_type OCCURS 0,
          File                      TYPE ttab_type OCCURS 0,
          END OF table_type.
    Suppose I have one record inside my internal table with struct as "STRUCTURE", fields have an internal table content of set of fields and File has some set of records.
    Now I want to create dynamic internal table whose name will be "STRUCTURE" , the fields of the dynamic internal table structure[] will be as in fields, and the records will be as in File.
    Like this if i have 100 records in my internal table then I have to create 100 dynamic internal table dynamically.
    Can anyone suggest how to do this?

    Hello,
    If you are talking about ALV then you can just the the table for empty columns before populating fieldcataloge and hide the columns.

  • No column text displayed in alv when i use dynamic internal table

    Hi friends,
    when I use dynamic internal table to display the fields in ALV formant, field column text was not displaying ,
    total row of column text was blank.
    can u sujjest me in this...
    with regards,
    prasad.

    Hi
    That depends on how you've filled the catalog table, here u need to insert the description for the labels (short, medium and long) and the description for the layout variant management.
    So u make sure to fill the fields like
    SCRTEXT_L
    SCRTEXT_M
    SCRTEXT_S
    REPTEXT

  • ALV rows to column dynamic internal table

    Hello People ,
    I am stuck in a report which displays an output in ALV as follows :-
    bukrs | kntyp | konto | knfix  | period     | element    | emeng  | emein
    1000  | 10      | 1100 | berlin | 11.2011  |      AG      |  0.148    | kgAG
    1000  | 10      | 1100 | berlin | 11.2011  |      AU      | 0.104    | kgAU
    1000  | 10      | 1100 | berlin | 11.2011  |      GA     | 0.207    | kgGA
    And this table has many values corresponding to element AG,AU and GA respectively . For example , there would be many element AG's with many "EMENG" values . Similarly for AU and GA .
    MY question :- I am asked to make AG , AU , GA as 3 different fields which should show the value "EMENG" under respective elements . Like :-
    bukrs | kntyp | konto | knfix  | period     |   AG       |   AU      |  GA     |    emein
    1000  | 10      | 1100 | berlin | 11.2011  |   0.148    |   0.104  |  0.207 |    kgAG
    That should be my output . ( elements replaced by AG , AU and GA which comes from a Metal table ZXXXX where
    metal no. 1 = AU
    metal no. 2 = AG
    metal no. 3 = GA
    If there is any metal added to it would be metal no. 4 ,5,6,7 .... so on ) and then that should be added as a field in our report .. So that has to be DYNAMIC .
    I am unable to move on with problem . Pls suggest ? I am pasting my report here ...

  • 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    -
