How to create an dynamic internal table with the structure of a ddic table

Question

Hi all,
I want to fill ddic-tables (which I already created) in my abap dictionary with data out of CSV-files (which are located on the CRM-Server).  The ddic tables have different amount of fields.
I started with creating a table which contains the name of the tables and the path to the matching CSV-file.
At the beginning I'm filling an internal table with part of this data (the name of the ddic-tables) - after that I am looping at this internal table.
LOOP AT lt_struc ASSIGNING <lfs_struc>.
     LOOP AT lv_itab1 INTO lv_wa1 WHERE ztab_name = <lfs_struc>.
     lv_feld = lv_wa1-zdat_name.
    ENDLOOP.
    CONCATENATE 'C:\-tmp\Exportierte Tabellen\' lv_feld INTO lv_pfad.
    Do.
    OPEN DATASET lv_pfad FOR INPUT IN TEXT MODE ENCODING NON-UNICODE IGNORING CONVERSION ERRORS.
    READ DATASET lv_pfad INTO lv_rec.
    IF sy-subrc NE 0.
      EXIT.
    ENDIF.
    enddo.
    REPLACE ALL OCCURRENCES OF '"' IN lv_rec WITH ''.
    SPLIT lv_rec AT ';' INTO TABLE lt_str_values.
    INSERT into (<lfs_struc>) values lr_str_value.
    CLOSE DATASET lv_pfad.
endloop.
This is not the whole code, but it's working until
SPLIT lv_rec AT ';' INTO TABLE lt_str_values.
I want to split all the data of lv_rec into an internal table which has the structure of the current ddic-table, but I didn't find out how to do give the internal table the structure of the ddic-table. In the code I used an internal tyble type string but I should be the structure of the matching tabel.
If I try to create an internal table by using a fiel symbol, I am told, that the data types are not matching.
Has anyone an idea?

Hi Mayari,
though you were successfull with
METHOD cl_alv_table_create=>create_dynamic_table
I must warn you not to use it. The reason is that the number of tables created is limited, the method uses GENERATE SUBROUTINE statement and this triggers an unwanted database commit.
If you know the DDIC structure, it is (starting with ECC6.0) much easier:
field-symbols:
  <table> type standard table.
data:
  lr_data type ref to data.
Create data lr_data type table of (<DDIC structure>).
assign lr_data->* to <table>.
The split code can be simplified gaining speed loosing complexity not loosing functionality.
field-symbols:<fs_s> type any.
field-symbols:<fs_t> type any.
SPLIT lv_rec AT ';' INTO table it_string.
loop at it_string assigning <fs_s>.
  assign component sy-tabix of wa_string to <fs_t>.
if sy-subrc = 0.
  <fs_t> = <fs_s>.
endif.
at last.
  append <fs_itwa3> to <ft_itab3>.
endat.
endloop.
Though it may work as Keshav.T suggested, there is no need to do that way.
