Use a string to define data

Question

Hello experts
Is there a way to do this: get a table name as a string  from a query and use it to define another variable
For example:
data: line TYPE RSDSSEG.
select * from RSDSSEG into line where DATASOURCE = '/CW1/MMD01'.
ENDSELECT.
psatablename = line-psa.
*now psatablename contains the name of the abap table i would like to read
the following two lines do not work
data: psaline type psatablename.
select * from psatablename into psaline.
Thanks a lot for your help

Yes it is possible.
Pl. check this sample code.
DATA:
      dy_table TYPE REF TO data,
      dy_line TYPE REF TO data.
FIELD-SYMBOLS                                                       *
FIELD-SYMBOLS: <dyn_table> TYPE STANDARD TABLE,
               <dyn_wa> TYPE ANY.
Create internal table dynamically with the stucture of table name
  CREATE DATA dy_table TYPE STANDARD TABLE OF (psatablename).
  ASSIGN dy_table->* TO <dyn_table>.
  IF sy-subrc = 0.
Create workarea for the table
  CREATE DATA dy_line LIKE LINE OF <dyn_table>.
  ASSIGN dy_line->* TO <dyn_wa>.
Select data from table
  SELECT * FROM (psatablename)
  INTO TABLE <dyn_table>.
  ENDIF.
