Populating data into internal table created dynamically

[Former Member]

Hi all,

I have created an internal table dynamically using the method

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE

EXPORTING

IT_FIELDCATALOG = IT_FIELDCAT2[]

IMPORTING

EP_TABLE = L_TABLE.

ASSIGN L_TABLE->* TO <IT_TABLE>.

CREATE DATA wa_table LIKE LINE OF <it_table>.

ASSIGN wa_table->* TO <wa_table1>.

when I tried to append data into the internal table <it_table>

as below

ex : <wa_table1>-prueflos = wa_item-prueflos.

it is giving the error as 'The data object <wa_table1> has no structure therefore no component called prueflos'.

can anybody tell me how to append data into a dynamically created internal table.

Thanks,

Sudheer

FAQ. You have to use [ASSIGN COMPONENT OF STRUCTURE|http://help.sap.com/abapdocu_70/en/ABAPASSIGN_MEM_AREA_DYNAMIC_DOBJ.htm#!ABAP_ALTERNATIVE_4@4@] to populate data to the dynamic internal table.

Hi Sudheer,

You need to use the ASSIGN COMPONENT command for this purpose. Check this code:

 FIELD-SYMBOLS: <t_dyntable> TYPE STANDARD TABLE,  u201C Dynamic internal table name 
               <fs_dyntable>,                     u201C Field symbol to create work area 
               <fs_fldval> type any.              u201C Field symbol to assign values  

* ***....
* ***....
* ***....
* ***....

* Assume your internal table has fields COL1, COL2, COL3 etc
  DO p_cols TIMES.  

    index = sy-index. 

    MOVE sy-index TO wa_colno. 

    CONCATENATE 'COL' 

                wa_colno 

           INTO wa_flname.  

* Set up fieldvalue 

    CONCATENATE 'VALUE' index INTO 

                fieldvalue. 

    CONDENSE    fieldvalue NO-GAPS.  

    ASSIGN COMPONENT  wa_flname 

        OF STRUCTURE <fs_dyntable> TO <fs_fldval>. 

    <fs_fldval> =  fieldvalue.  

  ENDDO.  

Hope this solves your problem!

Cheers,

Shailesh.

Hi,

Actually my data is in another internal table.

Based on some conditions I have to move the data into my dynamic internal table.

Can you tell me how to move the data from one internal table to dynamic internal table.

Thanks,

Hi Sudheer,

I have exact requirement as before: kindly see the resolved thread: [ How to insert a header string to a DYNAMIC Internal Table|;

Please let me know if I can provide more info or you need the actual code. Thanks.

Please check this example.............

FIELD-SYMBOLS: <t> TYPE STANDARD TABLE,
                            <wa_t>  TYPE ANY,
                            <field> TYPE ANY.

TYPES : BEGIN OF t_tab,
                test1 TYPE c,
                test2 TYPE c,
              END OF t_tab.
 
DATA : table     TYPE STANDARD TABLE OF t_tab,
            wa_table  TYPE t_tab,
            table1    TYPE STANDARD TABLE OF t_tab,
            wa_table1 TYPE t_tab.

ASSIGN ('WA_TABLE') TO <wa_t>.
ASSIGN ('TABLE')    TO <t>.

wa_table1-test1 = '1'.
wa_table1-test2 = '2'.
APPEND wa_table1 TO table1.

LOOP AT table1 INTO wa_table1.
  ASSIGN COMPONENT 'TEST1' OF STRUCTURE <wa_t> TO <field>.  "Refer a particular field
  <FIELD> = wa_table1-test1.

  ASSIGN COMPONENT 'TEST2' OF STRUCTURE <wa_t> TO <field>.  "Refer a particular field
  <FIELD> = wa_table1-test2.

  APPEND <wa_t> TO <t>.
ENDLOOP.
