Problem with GET REFERENCE statement

Question

Hi gurus,
shortly; I need to populate a table whose elements are made as follows:
CODE   TYPE MDM_FIELD_CODE (a string, basically)
VALUE  TYPE REF TO DATA.
I need to loop over an item table and populate the above sketched table; so I wrote as follows:
LOOP AT lt_item INTO ls_item.
*** MDMSRM_SHORT_DESCRIPTION ***
     CLEAR value_pair.
     MOVE 'MDMSRM_SHORT_DESCRIPTION' to value_pair-code.
     GET REFERENCE OF ls_item-short_desc INTO value_pair-value.
     APPEND value_pair TO lt_value_pair.
ENDLOOP.
The problem is: each time the loop is performed, all the VALUE fields already appended have the value of the last iteration.
How can I overcome this problem? Is there a sort of unassignment technique for GET REFERENCE?
Thanks,

Had some difficulties in working with field-symbols as I have to reference to a structure which is partly derived from the workarea and partly fixed...
I did as follows, maybe it's not the best solution, however, seems to work:
FIELD-SYMBOLS <item>        TYPE zsrm_cat_files_i.
FIELD-SYMBOLS: <minqty>      TYPE mdm_gdt_quantity-content.
FIELD-SYMBOLS: <minqty_unit> TYPE MDM_CDT_MEASURE_UNIT_CODE.
FIELD-SYMBOLS: <minqty_struct> TYPE mdm_gdt_quantity.
DATA minimum_qty TYPE REF TO mdm_gdt_quantity
LOOP ... ASSIGNING <item>.
   CREATE DATA minimum_qty.
   ASSIGN minimum_qty->* TO <minqty_struct>.
   ASSIGN COMPONENT 1 OF STRUCTURE <minqty_struct> TO <minqty>.
   ASSIGN COMPONENT 2 OF STRUCTURE <minqty_struct> TO <minqty_unit>.
   <minqty> = <item>-min_qty.
   <minqty_unit> = '$$$'.
   GET REFERENCE OF <minqty_struct> INTO value_pair-value.
   APPEND value_pair TO lt_value_pair.
