Call program using submit with variant that changing value

Question

Hi All,
I need to call a report with variant and abstract the data back to my current program.
so far,
i use following method
SUBMIT RFITEMAR USING SELECTION-SET 'XXX'
       EXPORTING LIST TO MEMORY
       AND RETURN.
DATA list_tab TYPE TABLE OF abaplist.
CALL FUNCTION 'LIST_FROM_MEMORY'
  TABLES
    listobject = list_tab
  EXCEPTIONS
    not_found  = 1
    OTHERS     = 2.
  DATA: L_ABAPLIST LIKE ABAPLIST OCCURS 0.
  DATA: BEGIN OF L_ASCITAB OCCURS 0, 
            LINE(2048),
          END OF L_ASCITAB.
  CALL FUNCTION 'LIST_TO_ASCI'
       EXPORTING
            LIST_INDEX         = -1
       TABLES
            LISTASCI           = L_ASCITAB
            LISTOBJECT         = list_tab
       EXCEPTIONS
            EMPTY_LIST         = 1
            LIST_INDEX_INVALID = 2
            OTHERS             = 3.
However, the problem is that i need to get some value from variant 'XXX' and keep changing it.
I have try function module "RS_VARIANT_VALUES_TECH_DATA" to get the variant details.
But, it just doesn't get me back all the details of the variants.
Are there any way i could read the variants in detail? i even try to read LRAW data from table vari. but there are no function module to convert the LRAW to either char or STRING.
Thanks.

You can use the FM "RS_CHANGE_CREATED_VARIANT" to change the variant values for already created variant and the FM "RS_VARIANT_CONTENTS" to get the variant values. Instead of changing the variant values and then passing to the Submit, you can directly pass the values to the Submit through..WITH SELECTION-TABLE seltab or ... WITH p IN sel variant of the Submit.
