Suggestions to find the current active fields in debugging mode

Question

Hi All,
I need to validate a particular entry in the screen in a particular subroutine(inside a user exit). I know the field gets populated but do not know which field is that, is there a way to know the current active fields in the debugging mode.

Hi,
  You can create dynamic types and data for those types are run time.
  lets assume that you have structure of some type and you have work area of that type.
DATA: lv_data type SPFLI.
DATA: lr_rtti_struc TYPE REF TO cl_abap_structdescr.
DATA: lt_comp       TYPE cl_abap_structdescr=>component_table.
DATA: ls_comp       LIKE LINE OF lt_comp.
DATA: lr_data       TYPE REF TO data.
FIELD-SYMBOLS: <fs_data> TYPE ANY.
    lr_rtti_struc ?= cl_abap_structdescr=>describe_by_data( lv_data ).
    lt_comp = lr_rtti_struc->get_components( ).
"Now  lets remove two fileds from the table as follows.
LOOP AT lt_comp into ls_comp.
DELETE lt_comp INDEX sy-tabix.
IF sy-tabix = 2.
EXIT. " Delete two components of the structure now lt_comp as two components less from SPFLI
ENDIF.
ENDLOOP.
    CALL METHOD cl_abap_structdescr=>create
      EXPORTING
        p_components = lt_comp
        p_strict     = abap_false
      RECEIVING
        p_result     = lr_rtti_struc.
CREATE DATA lr_data TYPE HANDLE lr_rtti_struc. "Now you have data of the new type
    ASSIGN lr_data->* TO <fs_data>.
    CREATE DATA lr_table LIKE STANDARD TABLE OF <fs_data>.
    ASSIGN lr_table->* TO <fs_table>.
