Cl_abap_typedescr= describe_by_data

We've just upgraded from 4.6 to ECC 6.0 and found that the result from cl_abap_typedescr=>describe_by_data differs.
In 4.6 the result in field ABSOLUTE_NAME referes to the definition in the main program. In 6.0 we get the definition from the type-pool in which the type is created. Does anyone know of a way to get the 4.6 type of result in ECC 6.0
Thanks in advance,
Arthur

Cl_abap_typedescr= describe_by_data( gt_table )

Afternoon all
I am using cl_abap_typedescr=>describe_by_data( <gt_table> ) to retrieve the fieldlist of my dynamically created ALV fieldcatalog. However, I have just switched to using some fields that are of type INT and now the method ignores them. Is this correct??? Is there another method that I should be using? I am on 46B.
Cheers
Ian

Ya...as rightly said by Vamsi...
change your declaration as
l_descr_ref TYPE REF TO cl_abap_tabledescr,
It will work....and for your information you can also use the below codes for getting components..
DATA: lv_ref_table        TYPE REF TO cl_abap_tabledescr,
       lv_ref_struct       TYPE REF TO cl_abap_structdescr,
lv_ref_table ?= cl_abap_tabledescr=>describe_by_data( et_data ).
lv_ref_struct ?= lv_ref_table->get_table_line_type( ).
lt_details[]   = lv_ref_struct->components.

CL_ABAP_TYPEDESCR - DESCRIBE_BY_DATA field length is doubled

I have a custom program developed on Non Unicode system, that is using CL_ABAP_TYPEDESCR -> DESCRIBE_BY_DATA to get field lengths of the fields in a structure. The code works perfectly file on Non Unicode system where it is developed, However when the same code is imported on a UNICODE system the field lengths of the fields in the same structure are exactly doubled. Anybody has any idea, why this may be happening?

> However when the same code is imported on a UNICODE system the field lengths of the fields in the same structure are exactly doubled. Anybody has any idea, why this may be happening?
Yes - because Unicode uses two bytes to represent ONE character.

Class CL_ABAP_TYPEDESCR's method DESCRIBE_BY_DATA

Hello!
How can I call CL_ABAP_TYPEDESCR's Method DESCRIBE_BY_DATA
with the CALL command ?
Many thanks in advance for your kindly efforts.
Reagards
Ilhan

Hi Ilhan,
In the abap editor, place the cursor where you want to put the CALL.
1->click the "Pattern" button (CTRL F6)
2->choose the radio button "ABAP Object patterns", Click Enter
3->in then next popup, choose the first radio button "Call Method"
4->Enter "CL_ABAP_TYPEDESCR" in the class name field
5->Enter "DESCRIBE_BY_DATA" in the method field, click Enter
you have the pattern in the editor
OR
you may copy the following code, and pass the parameters
data: l_describe TYPE REF TO cl_abap_typedescr.
field-symbols: <field>.
data: field_name(15).
ASSIGN TABLE FIELD (field_name) TO <field>
call method cl_abap_typedescr=>describe_by_data
exporting
    p_data      = <field>
receiving
    p_descr_ref = l_describe
Or Simply
ASSIGN TABLE FIELD (field_name) TO <field>.
l_describe = cl_abap_typedescr=>describe_by_data( <field> ).
Hope this helps,
Sajan Joseph.

Dynamic programming using cl_abap_typedescr

I have created a field catalog for an ALV grid dynamically using cl_alv_table_create=>create_dynamic_table (I am on 46B and cannot use the new version). How do I create the structure and therefore internal table to pass into the it_outtab parameter of the ALV grid set_table_for_first_display
method? I can create a blank table with the correct dynamic columns but now wish to populate it without much success! I am retrieving the type using cl_abap_typedescr=>describe_by_data and can cycle through the key but how do I just obtain the structure?

cl_abap_typedescr to retrieve the column names of a dynamic table I have created for using with an ALV grid

Hi,
Use ASSIGN r_dyn_table->* TO <t_dyn_table> to get access to the dynamic table. To append rows to it, you should use ASSIGN COMPONENT idx/name OF STRUCTURE struc TO <fs>.
Example:
    data: tab_fields like table of wa_fields,
         r_dyn_table TYPE REF TO data,
         r_wa_dyn_table   TYPE REF TO data,
         f_int type i.

        ep_table                  = r_dyn_table
      EXCEPTIONS
        generate_subpool_dir_full = 1
        OTHERS                    = 2.
      ASSIGN r_dyn_table->* TO <t_dyn_table>.
      CREATE DATA r_wa_dyn_table LIKE LINE OF <t_dyn_table>.
      ASSIGN r_wa_dyn_table->* TO <wa_dyn_table>.
      DESCRIBE TABLE tab_fields lines f_int.
      do f_int times.
        READ TABLE tab_fields INDEX sy-index into wa_fields.
        ASSIGN wa_fields-field TO <w_field1>.
        check1 = sy-subrc.
        ASSIGN COMPONENT sy-index
               OF STRUCTURE <wa_dyn_table> TO <w_field2>.
        check2 = sy-subrc.
        if check1 = 0 and check2 = 0.

CL_ABAP_TYPEDESCR

If I create a user defined type with reference to a DDIC object I can obtain the list of fields in the user defined type and the obsolute name which contains the user defined type by calling method describe_by_data of class cl_abap_structdescr at run time.

Dynamic types with CL_ABAP_TYPEDESCR

Hi,
I have a problem. I want to read out the output_length of dynamic types to evaluate inputs. I do something like the code below.
DATA type_ref      TYPE REF TO cl_abap_typedescr.
DATA elem_descr TYPE REF TO cl_abap_elemdescr.
DATA struc_descr TYPE REF TO cl_abap_structdescr.
type_ref = cl_abap_typedescr=>describe_by_data( <fs_lsinto> ).
elem_descr ?= type_ref.
elem_descr->output_length
But sometimes type_ref give back a CL_ABAP_STRUCTDESCR and I get a dump at '?='.
How I can solve my Problem?

How about something like this.
report zrich_0001.
data type_ref type ref to cl_abap_typedescr.
data elem_descr type ref to cl_abap_elemdescr.
data struc_descr type ref to cl_abap_structdescr.
data comp_tab type abap_compdescr_tab.
data comp_wa like line of comp_tab.
parameters: p_name(30) type c.
type_ref = cl_abap_typedescr=>describe_by_name( p_name ).
if type_ref->type_kind = 'u'.            " <- Structure
struc_descr ?= type_ref.
loop at struc_descr->components into comp_wa.
    catch system-exceptions move_cast_error = 1.
      data: tab_component type string.
     concatenate p_name comp_wa-name into comp_wa-name separated by '-'.
      elem_descr ?= cl_abap_typedescr=>describe_by_name( comp_wa-name ).
    endcatch.
    write:/ comp_wa-name, comp_wa-length, elem_descr->output_length.
endloop.
else.
elem_descr ?= type_ref.
write:/ p_name, elem_descr->output_length.
endif.

Problem about CL_ABAP_TYPEDESCR

Hi Buddies,
There was a strange problem which I encountered today.When I called the method cl_abap_typedescr=>describe_by_data to obtain the components of the table DD01T, the length of each component of this table was doubled.After I used this components table to create an internal table dynamically, the problem is occured due to doule length of the true lengh..
Suddently I realized that the problem was caused by UNICODE.Did anyone has the idea to get the right length?
DATA: structtype TYPE REF TO cl_abap_structdescr.
structtype ?= cl_abap_typedescr=>describe_by_data( u2018DD01Tu2019 ).

Hello,
I used POSID instead of PSPNR.

Resolving data-reference at runtime ( cl_abap_typedescr)

Hi all,
At runtime, I need to find out if a data-reference of created data
refers to a data-element or not.
In will give you an example of what I mean:
data: dummy         TYPE bukrs,
      descr_ref     TYPE REF TO cl_abap_typedescr,
      descr_datael TYPE REF TO cl_abap_elemdescr,
      p_datael      type string value ''.
descr_ref = cl_abap_typedescr=>describe_by_data( dummy ).
MOVE descr_ref ?TO descr_datael.
p_datael = descr_datael->help_id. "p_datael has now value BUKRS
How is this done, if we work with a datareferences?
I'm pretty sure it should be feasible - but I'm stuck here...
Task: same as above - find out data-element of dummy.
data: dummy         TYPE ref to data,
      descr_ref     TYPE REF TO cl_abap_typedescr,
      descr_datael TYPE REF TO cl_abap_elemdescr,
      p_datael      type string value ''.
create dummy type bukrs.
descr_ref = cl_abap_typedescr=>describe_by_data( dummy ).
"descr_ref->type_kind this time indicates, that we work with referenced data.
"How to progress from here on?
Thanks in advance. Points will be granted if issue can be solved!

How to Get data into I_ table which is Created dynamically

Hi Guys ,
I created one dynamic internal table , now I am want to display same internal table in my ALV? , how can I populate data into this internal table from my internal table based on some condition.
My Requirement is?
I have to display like this
1.This is my heading (field_cat of my ALV in which pack size may varry based on the flavor).
Plant flavor pack_size1----
pack_size-n
2. I have internal table( itab2) with all the pack-sizes and plant details.
3. how can I pass the these data into (itab1) which going to display in ALV ?
I can loop at itab2.
How to pass this data into itab1 relevent fields ?
Looking for Val. Inputs
With Best Regards

Hi,
This is a code snippet.
    DATA: r_dyn_table      TYPE REF TO data,
          r_wa_dyn_table   TYPE REF TO data,
          l_fields_table type SOI_FIELDS_TABLE.
    FIELD-SYMBOLS: <t_dyn_table>    TYPE STANDARD TABLE,
                   <wa_dyn_table>   TYPE ANY,
                   <w_field1>        TYPE ANY,
                   <w_field2>        TYPE ANY.
    DATA: l_oref_structure TYPE REF TO cl_abap_structdescr,
          l_abap_compdescr type abap_compdescr.
    data: check1 type i,
          check2 type i,
          l_range(20).
    r_dyn_table = IL_DYNDATA-r_dyn_table.
    ASSIGN r_dyn_table->* TO <t_dyn_table>.
    CREATE DATA r_wa_dyn_table LIKE LINE OF <t_dyn_table>.
    ASSIGN r_wa_dyn_table->* TO <wa_dyn_table>.
    l_oref_structure ?= cl_abap_typedescr=>describe_by_data(
                         wa_supl ).
    loop at il_fill_itab into wa_supl.
      loop at l_oref_structure->COMPONENTS into l_abap_compdescr.
        ASSIGN COMPONENT l_abap_compdescr-name
               OF STRUCTURE wa_supl TO <w_field1>.
        check1 = sy-subrc.
        ASSIGN COMPONENT l_abap_compdescr-name
               OF STRUCTURE <wa_dyn_table> TO <w_field2>.
        check2 = sy-subrc.
        if check1 = 0 and check2 = 0.
          <w_field2> = <w_field1>.
        endif.
      endloop.
      APPEND <wa_dyn_table> TO <t_dyn_table>.
    endloop.
You can access your dynamic internal table via a field symbol.

Nested structure when using FM XXL_SIMPLE_API

I use this logic to fill in the headings before calling the FM xxl_simple_api in one of my programs. Is it possible to have nested structure(for <b>i_tab</b> in my code) and still use same kind of logic to fill in the headings? Not sure if this Fm would display data correctly when there is a component of strucutre type. I tried it, the field was blank with no contents in excel.
DATA : nlines TYPE i,
         tempfile LIKE gxxlt_f-file,
         descr_ref TYPE REF TO cl_abap_structdescr,
         header LIKE gxxlt_v OCCURS 0 WITH HEADER LINE,
         it_print LIKE gxxlt_p OCCURS 0 WITH HEADER LINE.
*data:               keycol type i.
FIELD-SYMBOLS:
<comp_wa> TYPE abap_compdescr,
tempfile = file_name.
REFRESH header.
CLEAR header.
descr_ref ?= cl_abap_typedescr=>describe_by_data( i_tab ).
DESCRIBE TABLE descr_ref->components LINES nlines.
nlines = nlines + 1.
LOOP AT descr_ref->components ASSIGNING <comp_wa>.
    IF sy-tabix = nlines.
      EXIT.
    ELSE.
      header-col_no = sy-tabix.
      header-col_name = <comp_wa>-name.
      APPEND header.
    ENDIF.
ENDLOOP.
CALL FUNCTION 'XXL_SIMPLE_API'
EXPORTING
    filename = tempfile
N_KEY_COLS = keycol
TABLES
   col_text = header[]
I appreciate your help. Thanks

Hi,
It's better to use another FM 'SAP_CONVERT_TO_XLS_FORMAT'
call function 'SAP_CONVERT_TO_XLS_FORMAT'
             exporting
              I_FIELD_SEPERATOR = seper
              I_LINE_HEADER = 'X'
                 I_FILENAME = P_FILE
              tables
                  I_TAB_SAP_DATA = itab
              exceptions
                  CONVERSION_FAILED = 1.
