Help on Report Layout Variant.

Question

Hello,
I have a requirement as stated below:
I have a custom report and it displays say 15 fields. I have created a variant for it to display only 10 fields.
Now, is there a Function Module or a report that will give me details of these 10 fields that I have chosen.
Basically I want to know if there is a FM that gives details of a report layout variant by just passing the report name and the variant name etc?
Thank,
Ketan.

Hi Ketan,
check this FM : REUSE_ALV_VARIANT_SELECT
sample code :
DATA: g_variant          LIKE disvariant.
CONSTANTS:
  g_x            VALUE 'X'.
DATA: g_fieldcat_tab     TYPE slis_t_fieldcat_alv.
DATA: g_layout           TYPE slis_layout_alv.
DATA: g_fieldcat_tab     TYPE slis_t_fieldcat_alv.
DATA: g_sortfields_tab   TYPE slis_t_sortinfo_alv.
DATA: g_filter_tab       TYPE slis_t_filter_alv.
  IF NOT g_variant-variant IS INITIAL.
    CALL FUNCTION 'REUSE_ALV_VARIANT_SELECT'
         EXPORTING
              i_dialog            = ' '
              i_user_specific     = g_x
              i_default           = ' '
            I_TABNAME_HEADER    =
            I_TABNAME_ITEM      =
              it_default_fieldcat = g_fieldcat_tab[]
              i_layout            = g_layout
         IMPORTING
            E_EXIT              =
              et_fieldcat         = g_fieldcat_tab[]
              et_sort             = g_sortfields_tab[]
              et_filter           = g_filter_tab[]
         CHANGING
              cs_variant          = g_variant
         EXCEPTIONS
              wrong_input         = 1
              fc_not_complete     = 2
              not_found           = 3
              program_error       = 4
              OTHERS              = 5.
    IF sy-subrc IS INITIAL.
    ENDIF.
ENDIF.
