How to create dynamic nested internal table

Hi Experts,
Pleae tell me or give sample code, how to create dynamic nested internal table ?
I have seen threads saying creation of dynamic internal tables using some table structure only. But now the requirement is to create dynamic nested internal table.
For example the internal table contains two fields viz., one is field1 of dynamic internal table and other is normal field2 and values as shown below:
Nested internal table:
field1 | field2 ...
<table content1> | value2..
<table content1> | value2..
Here the [table content] should also a dynamic internal table.
Let me know if you need any other info.

[Updated] How to create copies of internal table?

Dis is the detailed description of a problem i have and i
tried all i can to solve it without satisfied results.
I want to copy an internal table of a type defined in the
ABAP program itself, not dictionary. I have a function
that is supposed to accept the internal table as a
parameter of type 'any table'. The function should create
the new internal table using the field catalog of the
passed 'any table' and then create a new internal table
using "create_dynamic_table" and return the DATA pointer.
If anyone knows how it is done pls help me out.
I would like to get the field catalog of the following
internal table automatically by using some sap function..
TYPES:
BEGIN OF MYTYPE,
NAME TYPE SOMEZTABLE-NAME,
AGE TYPE SOMEZTABLE-AGE,
END OF MYTYPE.
DATA:
IT_TABLE TYPE TABLE OF MYTABLE INITIAL SIZE 0.
DATA:
COPY_OF_IT_TABLE TYPE REF TO DATA.
SELECT NAME AGE INTO TABLE IT_TABLE FROM S0MEZTABLE.
PERFORM CREATECOPY USING IT_TABLE CHANGING COPY_OF_IT_TABLE.
[I have used FORM 4 understanding purpose only. I
actually want to put the code in the form in a seperate
global class method. So, its not possible to define
field symbols in the main pgm and assign value to it
from within the FORM. Also we cant CREATE DATA of the
type 'mytype' within the FORM.]

HOW TO CREATE A FINAL INTERNAL TABLE FROM 8 OTHER INTERNAL TABLES

I have around 8 internal tables and I need to merge all of them into one final internal table so that I need to pass the new internal table for ALV Grid display

Hi Balram,
Assuming that there are logical links (ie foreign key relationships) between each of these internal tables, on way is to do several loops controlled by a binary search.
eg. we have 2 tables:
types: begin of ty_makt,
            matnr type matnr,
            maktx type maktx,
          end of ty_makt.
types: begin of ty_mara,
            matnr type matnr,
            bismt type bismt,
          end fo ty_mara.
types: begin of ty_output,
            matnr type matnr,
            bismt type bismt,
            maktx type maktx,
          end of ty_output.
data: tbl_mara type table of ty_mara with header line,
        tbl_makt type table of ty_makt with header line,
        tbl_putput type table of ty_output with header line.
sort tbl_makt by matnr.
loop at tbl_mara.
read table tbl_makt with key matnr = tbl_mara-matnr binary search.
if sy-subrc eq 0.
* build tbl_output here
endif.
endloop.
Hope this helps.
Cheers,
Pat.

How to Create Dynamic form using table data

Dear All,
I have one Table called PRODUCT_MASTER where product details are stored. Say product A,B,C,D are stored in the table. Another table called SUB_PRODUCT_MASTER, which contains sub product details.Say A1,A1,B1,B2, B3,C1, C2, C3, D1,D2,D3.
Now, I want to create a dynamic form based on product,sub product. for a whole month. For better under standing here is the format.
PRODUCT A B C D
SUB_PROD A1 A2 B1 B2 B3 C1 C2 C3 D1 D2 D3
Days
1 x x x x x x x x
2
3
4
5
6
7
Now whenever I add one row in the PRODUCT)MASTER table and SUB_PRODUCT_MASTER table, Form should add one column in the form automatically. e.g. If I add Product E with two Sub product E1 and E2 then form should add ptoduct E column in the form with sub products E1 and E2 as per above format. Here days are fixed to 31. This forms should accept product wise daily despatch entry. For
storing despatch entry another table is created.
Please help to create this type od forms.

How to create Dynamic Table Control

Hi
How to create Dynamic Table control , The field names and values to be displayed in table control are to be fetched from Add-on Tables.
Regards
Prasath

Hi Jonathan,
Actually the columns to be displayed are not constant . It will be increased based on the database values, Anyhow it will not exceed 100.
Please confirm my understanding.
1. In this case I have to create 100 custom columns and make it visible / invisible based on my requirement and I can set the title at runtime.
2. How can i assosicate / reassociate the datadictionary reference for the columns that i use. Because I need to show the search help values for the
dynamic columns.
Your opinion on this will be helpful.

Want to create dynamic SQL with table join

I want to create a dynamic SQL query so that the user can enter any two table names on the selection screen and two field names that he wants to join. After which i should be able to dynamically generate the SQL (native or open) and show the result as report. I have already read the forum threads and know how to create dynamic SQL for single table, what i m struggling with is how to do inner join. I know i can use nested select but that will make the query very slow because i want to extend it to more than 2 tables later.
Will give points to useful answer for sure, thanks for reading.

Hi,
Following is a piece of code which I have used in my program.
DATA: ws_flds(72)   TYPE c.
DATA: ftab LIKE TABLE OF ws_flds.
ws_flds = 'rbukrs rprctr racct ryear '.
APPEND ws_flds TO ftab.
   SELECT (ftab)
    INTO CORRESPONDING FIELDS OF TABLE it_grp_glpca
    FROM glpca FOR ALL ENTRIES IN i_cert_item
    WHERE kokrs = c_kokrs
        AND rldnr = '8A'
        AND rrcty IN ('0','2')
        AND rvers = '000'
        AND rbukrs = i_cert_item-bukrs
        AND ryear = p_ryear
        AND rprctr = i_cert_item-prctr
        AND racct = i_cert_item-saknr
        AND ( poper BETWEEN '001' AND ws_poper )
        AND aufnr IN s_aufnr
        AND kostl IN s_kostl
        AND rfarea IN s_fkber
        AND rmvct IN s_rmvct
        AND sprctr IN s_sprctr
        AND ( racct BETWEEN c_low AND c_high ).
You can now pass your table name as (p_table) or append fieldnames to the internal table (ftab). if it is join then you can append this table like abukrs asaknr..etc.

Hi Michelle,
          First of all Special thanks for your informative answers to my other forum questions. I really appreciate your help.
Coming back to this question I am still waiting for an answer. Please help. Note that my structure is not in a dictionary.
I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition
I have updated my code like the following and I am getting error:
TYPES: BEGIN OF t_type,
CARRID TYPE sflight-carrid,
CONNID TYPE sflight-connid,
END OF t_type.
Data: i_struc type table of t_type,
dyn_node type ref to if_wd_context_node,
rootnode_info type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
wa_node_att-name = 'CARRID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
insert wa_node_att into table i_node_att.
wa_node_att-name = 'CONNID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
attributes = i_node_att
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
But now I am getting the following error :

Create dynmic deep internal table

Dear all,
is it possible to create a dynamic internal table which has a deep structure. The catch here is that component tables of the main internal table will determined dynamically.
thanks a lot!!!
Navjot

Hi Navjot,
Dyanmic internal table with deep structure is specially useful when we have to create an ALV with Colors or Style etc. Since we have CL_ABAP_TABLEDESCR class from RTTS, it is also possible to create a dynamic internal table with the deep structure. To create an internal table with deep structure, we need to first get the object definition of the table type. Than we have to add that as a component of our table definition and that's it.
Try this :
*& Report ZNP_DYNAMIC_DEEP_TABLE.
*& Shows how to create dynamic internal table with deep strcuture
*& which can be used in the ALV to have Sytle table, Color table
* 2.1 Creating the Deep strcuture field

lo_tab ?= cl_abap_typedescr=>describe_by_name( 'LVC_T_SCOL' ).

la_comp-type = lo_tab.
APPEND la_comp TO lt_tot_comp.

I think nested and deep structure internal tables will not work with gui_download.
you need to convert before giving it to gui_download

*How can we use the internal table in module pool programming? Clarify plz*

If we creating a screen using the table having four fields(for e.g.). The screen has the functions of display, modify, delete, save, exit etc for the fields. The front-end of the screen having I/O fields of the table using internal table. How can we declare the internal table in the screen?

HI,
Create one WA for your Internal table and then map it to your fields.
For Example,
Data : begin of wa,
          name(10),
          age type i,
           end of wa.
data : it like table of wa with header line.
Then in screen create input fields with the name, age and ***.
Then the user entered values are stored in name age and ***.
then you can manipulate with that values using wa.
Thanks.

Nested Internal Table Tables and REUSE_ALV_GRID_DISPLAY

Types and internal tables are below. I have skimmed the code for the function module below, assume field category built, etc.. The table is in the tables portion of the function module, the nested internal table is inside of int_output defined as data: int_tlines type t_tline occurs 0.

Hi
I dont think this requirement is possible. Even if we pass the data through the nested internal table the FM may not give a dump. The main problem will be with field catalog. How can we build field catalog for the fields inside the nested internal table.
Field catalog for this FM REUSE_ALV_GRID_DISPLAY should be of type SLIS_FIELDCAT_ALV and this is a standard one.

Problem reading data from nested internal table.

Hi,
Below is my code;
*********SAP Code********
TYPES: BEGIN OF v54a0_scdd,
 fknum LIKE vfkk-fknum,
 change LIKE vfkkd-updkz,
 x TYPE v54a0_scd,
 y TYPE v54a0_scd,
 tvtf LIKE tvtf,
 END OF v54a0_scdd.
SCD table for dialog
TYPES: v54a0_scdd_tab TYPE v54a0_scdd OCCURS 1.
*********SAP Code********
*Custom declaration*****
data: wa_freight_costs type v54a0_scdd_tab.
data: it_freight_costs type v54a0_scdd_tab occurs 0.
*****Here data is getting appended to it_freight_costs. P_frieght_costs is coming from standard program.
 move p_freight_costs TO wa_FREIGHT_COSTS.
 append wa_freight_costs to it_freight_costs.
 clear wa_freight_costs.
***Now the problem is here. I am not able to read the data from the nested internal table x-item.
if i use <fs_f_costs> to move data from it_freight_costs in the outer loop, i get a syntax error; "the line type of the table it_freight_costs is not compatible with field symbol type <fs_f_costs>" 
 FIELD-SYMBOLS: <fs_f_costs> type line of v54a0_scdd_tab.
 LOOP AT it_freight_costs assigning <fs_f_costs>.
 LOOP AT <fs_f_costs>-x-item ASSIGNING <fs_freight_item>.
 I want to read <fs_freight_item>-vfkp-netwr.
 ENDLOOP.
Can anyone guide me?

A quick look at how I would do this. Note I haven't checked if this compiles just done a quick brain-dump.
DATA: lr_f_costs TYPE REF TO v54a0_scdd_tab,
 lr_f_cost TYPE REF TO v54a0_scdd.
LOOP AT it_freight_costs REFERENCE INTO lr_f_costs.
 LOOP AT lr_f_costs->* REFERENCE INTO lr_f_cost.
 ENDLOOP.
ENDLOOP.
As you can see I personally prefer pointers to field symbols - I don't believe there is any performance differences and because of my background in other languages pointers make more sense to me.
