Function "DDIF_NAMETAB_GET"

Question

Hi,
I am reading a database table's attributed using DDIF_NAMETAB_GET function. My code is:
DATA: IO_TABLE_NAME TYPE tabname,
  it_dfies TYPE TABLE OF dfies,
  is_dfies TYPE dfies.
DATA: is_x030l  TYPE x030l.
*IO_TABLE_NAME is getting from user
CALL FUNCTION 'DDIF_NAMETAB_GET'
           EXPORTING
                tabname   = IO_TABLE_NAME
           IMPORTING
                x030l_wa  = is_x030l
           TABLES
                dfies_tab = it_dfies
           EXCEPTIONS
                OTHERS    = 1.
LOOP AT it_dfies INTO is_dfies.
ENDLOOP.
Above, When I watching the is_dfies, there are some informations as:
"ZCALISAN      ID      0002000004     AKCNT"
I know that ZCALISAN is the name of database table, ID is the attribute of this table, AKCNT is the field type of this attribute.
Now,
1. I don't know 0002000004 mean? Or how to interpret this value?
2. I want to learn this table's primary key(s). But the table "it_dfies" includes only attribute information. How can I read primary keys? Is it possible to read primary keys using  FUNCTION 'DDIF_NAMETAB_GET'?
3. I want to see the field type AKCNT or another field type's Data Type. Is it char? If char what is long? Or is it Decimal? How can I do this operation?
4. The purpose of all of these operations copying one database table. For this purpose, I will read table's information then using EXEC SQL I will create the copied table. Using EXEC SQL can I define DECIMAL like in SAP, or all other types like in SAP? Is there any restriction?

Hi,
There are two problems that I need to solve:
1. In my program I want SRC_TABL and TGT_TABL from user. Then when I called Function 'RS_DD_COPY_OBJ'
CALL FUNCTION 'RS_DD_COPY_OBJ'
  EXPORTING
    SOURCE_NAME              = SRC_TABL
    TARGET_NAME              = TGT_TABL
    OBJTYPE                  = OBJECT_TYPE
  EXCEPTIONS
    NOT_EXECUTED             = 1
    PERMISSION_FAILURE       = 2
    OTHERS                   = 3.
This function has another screen that wants Source Table and Target Table. If user enters Source Table and/or Target Table different from at the beginnig of the program that user entered, I need to learn what user entered. Because, I also need to activate copied table. And also, I will copy all entries of Source Table to Target Table. Because of these, I need to learn what user entered for table names while FUNCTION 'RS_DD_COPY_OBJ' is running
2. As I mentioned above, I need to copy the source table's entries to target table. But source table's and target table's names are defined by user. So, I can not write this:
SELECT * FROM SOURCE_TABLE INTO TABLE ITAB.
INSERT DEST_TABLE FROM TABLE ITAB.
Program gives error about SOURCE_TABLE and DEST_TABLE.
Also, I can not define ITAB because of I do not know which table I will use before starting program.
How can I implement this copy operation? Is there any way? Is there any function that copies source table's entries to target table?
Thanks.
