Create internal table dynamically for IDoc fields

Hi,
I need to create an internal table dynamically based on the segment field names that are returned in the table pt_fields when calling function 'IDOCTYPE_READ_COMPLETE'. I see many posts suggesting classes such as 'cl_wrf_dynamic_table=>create_dynamic_table', but it does not work for me. The problem I have with the classes is that it doesn't allow you to have the same column name more than once. But in the scenario I am testing, I have some column names that are duplicated, and I cannot remove the duplicates. Are there any functions or classes that I can use to create a dynamic internal table that will not check if a column name is used twice?
Thanks,
Carrie

Hello Carrie
My first thought was that RTTI might be able to do this but it does not (see the dump below). And it is obvious that RTTI behave likes this.
Error analysis
    An exception occurred which is explained in detail below.
    The exception, which is assigned to class 'CX_SY_STRUCT_COMP_NAME', was not
     caught and
    therefore caused a runtime error.
    The reason for the exception is:
    Multiple Specification of the Name 'CUSTOMER' as a Component Name (Component 7)
Just think about any way to define statically an itab or structure containing duplicated field names. You will always get a syntax error irrespective of whether you use a DDIC structure, a TYPE or a DATA variable.
If there is no way to define such a structure statically why should it be different when defining dynamically?

Uwe

How to delete a field from a Dynamically created internal table

Hi friends,
I have got a requirement in which, I will be entering the table name and Excel file from seletion-screen.
based on the Table I have entered in the selection-screen I need to create a dynamic internal table so that I can fill that Execel data into that internal table and later i using BDC i can I can fill the database table using SM30 transaction.
here. my problem is that, When I am creating internal table dynamically, MANDT filed is also getting created in the internal table.
please, help in deleteing the filed MANDT from the internal able.
following is the code which creates the dynamic internal table.
CREATE DATA dy_table TYPE TABLE OF (p_tabname).
assign dy_table->* to <dyn_table>.
please provide, if any sample code is available.
Regards,
Xavier.P

Hi,
You can use this logic,
While creating the Dynamic filed catalog try to avoid MANDT field.
Ex:
*Dynamic creation of a structure
CREATE DATA LP_STRUCT TYPE (V_TABLE).
ASSIGN LP_STRUCT->* TO <FS>.
*Fields Structure
OF_SDESCR ?= CL_ABAP_TYPEDESCR=>DESCRIBE_BY_DATA( <FS> ).
LOOP AT OF_SDESCR->COMPONENTS ASSIGNING <COMPONENTS>.
*Field MANDT not displayed
    IF SY-TABIX = 1 AND <COMPONENTS>-NAME = 'MANDT'.
      CONTINUE. " Next loop
    ENDIF.
*Build Fieldcatalog
    LS_LVC_CAT-FIELDNAME = <COMPONENTS>-NAME.
    LS_LVC_CAT-REF_TABLE = V_TABLE.
    APPEND LS_LVC_CAT TO LT_LVC_CAT.
    CLEAR LS_LVC_CAT.
ENDLOOP.

How to fill internal table dynamically

Hi All,
   how to fill internal table dynamically.
for example:

now i want to append dynamically field itab-grade along with rest fields.
is this possible?? if yes kindly let me know how to do that.

How to create New columns for the Internal Table Dynamically?

HI Guys,
In my logic i have to create new columns depending on the logic which i am executing.
My requirement is .I have to display o/p like this
Material || Year || Period || Mix ratio || Vendor ||Mix Ratio || Vendor || Mix Ratio Vendor || Mix ratio || Vendor || Mix ratio.............................from table's CKMLMV003 and CKMLMV001.Her i have to display the o/p in the above format and i have to display Vendor and Mix Ratio for 5 columns irrespective of data .If i have more than 5 columns for any record then i have to create a New columns dynamically for Vendor and Mix ratio.If anybody want my code i can Submit But plz tell with example how to do?
<b>The O/P must be finally shown in ALV Grid</b>
Thanks,
Gopi

You must create the entire internal table dynamically, you can not add columns to a statically define internal table. Here is an example of creating a dynamic internal table.

Passing values to dynamically created internal table

Hi,
I have the flat file data as
f1,f2,f3........so on
where f1 f2 and f3 are field names.
I have a variable var which contains the data
V1,0001,0002.........so on
data: var type string.
The value of field f1 is v1
The value of field f2 is 0001
The value of field f3 is 0002.......so on
FIELD-SYMBOLS:     <fs_1> TYPE STANDARD TABLE
I have dynamically created an internal table for fields f1 f2 f3 ...... using
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog           = lt_fieldcatalog
    IMPORTING
      ep_table                  = <fs_data>
    EXCEPTIONS
      generate_subpool_dir_full = 1
      OTHERS                    = 2.
IF sy-subrc <> 0.
ENDIF.
ASSIGN <fs_data>->* TO <fs_1>.
Now for <fs_1> I have to pass the corresponding values of the fields f1 f2 f3 .
How can i solve this.
Thanks and regards ,
Parvatha Reddy

Hi,
There is no data in <fs_1>.
I need to pass the data form the string var to the fields of <fs_1>..
I understand that you want to populate the internal table <fs_1>.
for that you fist need work area.. use below statement to create work area..
DATA: new_line TYPE REF TO data.
CREATE DATA new_line LIKE LINE OF <fs_1>.
ASSIGN new_line->* TO <fs_2>.
<fs_2> is not your work aread...
to assign value to each field of you work aread <fs_2>. use statement
ASSIGN COMPONENT 1 OF STRUCTURE <fs_2> TO <fs_3>.
<fs_3> = f1 .
now <fs_3> will point to the first field of work area <fs_2>, f1 is value from your string .. repeat above for each field in workarea, by increasing the component number. Once your work area is filled
append it to table.
append <fs_2> to <fs_1>
apologies if I am not getting the requiremnt correctly..

Create Fieldcatalog based on internal table (dynamic)

Hi ,
Is there a way to create Create Fieldcatalog based on internal table (dynamic).
while creating fieldcat we usually many give the fields "fieldname" and "tabname".
is there a way to get the fieldname from the main table ?
Eg ..
I have i_tab as the output table. It has 3 fields "a", "b" and "c"
Now when i created fieldcat manually ( in case i cannot use fieldcat_merge FM) , i have to append 3 throws in fieldcat table.
These rows would have "a", "b" and "c".
Now i want to know if there is a way in which i can find "a" "b" and "c" fieldnames from the createdd internal tables.
i can then append the same to fieldcat.

Hi Anuj,
I created a FORM routine for this 4 or 5 years ago and made a couple of refinements. Meanwhile it has prooved as very useful.
The disadvantag is that it creates the oldfashioned field catalog for the function calls. But I already used it for OO fieldcatalog of LVC type - there is a function module for this but I do not have the name here.
You need the two forms (second called in first) to build the field catalog from any internal table that can be used for ALV display.

Declaring a field of an internal table dynamically...

Hi all,
I've to use an internal table which contains two field...
But i want to define its size at run time as per my requirements...
structure of internal table is very simple...
<b>types: begin of ty_tab,
            f1 (size i want dynamically),
            f2(1) type c,
           end of ty_tab.</b>
in my cases size of field f1 can be between 200 and 1000 approx..
<b>so how can i define the size of field f1 dynamically...</b>

Hi Balaji..
First I had calculated the size of the field to be created... suppose it is <b>w_len1</b>
data: t_fieldcat TYPE lvc_t_fcat,
wa_fieldcat TYPE lvc_s_fcat,
new_table TYPE REF TO data,
new_line TYPE REF TO data.
field-symbols: <t_tab> TYPE STANDARD TABLE,
<wa_str> type any.
wa_fieldcat-fieldname = 'FLD1'.
wa_fieldcat-tabname = 'TAB'.
wa_fieldcat-datatype = 'CHAR'.
wa_fieldcat-inttype = 'C'.
wa_fieldcat-intlen = w_len1. " determine during run time
APPEND wa_fieldcat TO t_fieldcat.
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
it_fieldcatalog = t_fieldcat
IMPORTING
ep_table = new_table.
ASSIGN new_table->* TO <t_tab>.
CREATE DATA new_line LIKE LINE OF <t_tab>.
ASSIGN new_line->* TO <wa_str>.
Earlier I wanted to use type string but I had to use this table further but type string was not supported for that purpose. So I had to do this..
I think this may be helpful..

Problem creating an internal table dynamically

Hi,
I'm trying to create an internal table dynamically as i would be able to determine the structure of the table based on the user input.
I've used the sample code from this forum ...

I'm able to get the structure of the table that i want, but when i'm trying to select data from the table into this internal table..as highlighted in the sample code above..i'm getting a short dump...saying that ' the database table is 600 bytes wide but the internal table is only 576 bytes wide.
The internal table is declared as
field-symbols: <dyn_table> type standard table..
Could anyone please tell me how to rectify this.
Thanks in advance,
Harsha.

Hi Smitha,
I'm building the internal table by getting the structure using the method
cl_abap_typedescr=>describe_by_name( p_table ).
where p_table is the table name determined dynamically..
Now using this structure, i'm building an internal table by calling the method
call method cl_alv_table_create=>create_dynamic_table
I've checked all the fields after the internal table has been created .. and it contains all the fields of the table that i'm supplying initially..
But when i read data into that internal table, it gives me that dump..I've described it in this post earlier.
Any more suggestions would be very helpful.
Thanks,
Harsha

Uploading data from excel file to a dynamically created internal table

Hi,
I have a requirement where i have to upload data from an excel file into a database table. I would be able to determine the structure of the table only at runtime based on the user input.. so i have created an internal table dynamically.
Could you please tell me if its possible to upload data from an excel file to the dynamically created internal table using any function modules?
I thought of doing this by declaring a generic internal table of one field and then uploading the *.csv file into it and then splitting it based on "," and then assigning it to the field symbol referencing the internal table.. but my file length exceeds 132 characters and i'm only able to get data of lenght 132 char's in my internal table ( generic one).
Could anyone please show me a way around this.
Thanks in advance,
Harsha

How to send Internal table records to Idoc Inbound posting FM to create Ido

Hello Experts,
I have all the data necessary to create shipments in one internal table inside my ABAP program.
I can use BAPI_SHIPMENT_CREATE to create shipments. But associated with this BAPi there is one ALE message type SHIPMENT_CREATEFROMDATA. Now my requirement is to use this message type to cretae my shipments via idocs for one scenario for some of the records in the internal table.
For this message type, I got the inbound function module IDOC_INPUT_SHIPMENT_CREATEFROM from TBDBE table.
Can anybody please let me know how to send the data from the internal table to this inbound function module?
Becasue it has mandatory parameters INPUT_METHOD, MASS_PROCESSING. What values should be passed to these parameters if the data has to be sent to this function module?
Regards.

Hi Ravikanth,
Thankyou very much for your quick reply.
So If I split my internal table data and populate IDOC_DATA and IDOC_CONTROL and pass to the inbound function module directly in my ABAP program, will that be going to create idocs and post shipments?
I mean is it enough to call the Inbound posting function module directly in my ABAP program or any other FMs to be called to take care of ALE settings and shipment creation?
Please confirm.
