Define work area with referencing to dynamic structure name

Check this coding:

PARAMETERS:
  p_type TYPE typename OBLIGATORY DEFAULT 'VBAK'.
DATA:
  gr_dataref  TYPE REF TO data.
FIELD-SYMBOLS:
  <gfs> TYPE ANY.

CREATE DATA gr_dataref TYPE (p_type).
ASSIGN gr_dataref->* TO <gfs>.

<gfs> will take the structure from the name parameter, in this case table VBAK by default.

So if you have VBAK data in your string, doing the assignment <gfs> = string would split the data over the different fields.

What this code is lacking is exception handling, which depends on the SAP version you're at.

If your WAS is >= 6.20, you can use exception classes, so you should catch exception CX_SY_CREATE_DATA_ERROR:

TRY.
  CREATE DATA gr_dataref TYPE (p_type).
    CATCH CX_SY_CREATE_DATA_ERROR.
      " Exception handling in here
ENDTRY.

On older releases you should use CATCH SYSTEM-EXCEPTIONS ... ENDCATCH instead.
