How to append lines of a dynamic internal table to another dynamic internal table of same type

Hi Experts,

Thanks for your valuable post !

I've one requirement and expecting the solution.

Requirement: How to append lines of a dynamic internal table to another dynamic internal table of same type.

Scenario: I've one Internal table ITAB1 having 100 records which is assigned to dynamic internal table <ITAB1>(so ITAB1 also have 100 records).

I want to get the 20 records from the dynamic internal table <ITAB1> to a second dynamic internal table <ITAB2> which is of same type as <ITAB1>.

I'm using the code : APPEND LINES OF <ITAB1> FROM  1 TO  20 TO  <ITAB2>.

But values are not getting inserted to <ITAB2>.

Code is below for your understanding what i'm doing: -

data : w_tabname TYPE w_tabname,

      w_dref TYPE REF TO data,

      w_grid TYPE REF TO cl_gui_alv_grid.

FIELD-SYMBOLS <ITAB1> TYPE STANDARD TABLE.

FIELD-SYMBOLS <ITAB2> TYPE STANDARD TABLE.


PARAMETERS: p_record type i.

PARAMETERS : p_table(50) TYPE C. "Taking Standard table from Selection Screen say "MARA"

  w_tabname = p_table. " Getting the table name from Selection screen

  CREATE DATA w_dref TYPE TABLE OF (w_tabname).

  ASSIGN w_dref->* TO <ITAB1>.

  ASSIGN w_dref->* TO <ITAB2>.

* Populating Dynamic internal table
SELECT * FROM (w_tabname) UP TO 20 ROWS  INTO TABLE <ITAB1>. "Values are comming in <ITAB1> without any problem

APPEND LINES OF <ITAB1> FROM  1 TO  20 TO  <ITAB2>. "This code is not getting executed successfully

Please help me with your valuable tips...

Thanks in Advance!
