Hi,

Try using function module SEO_COMPONENTS_SELECT.

Just fill the class name in the table CLIF_KEYS and call it to get back all the attributes and methods..

Here is some sample code to help you understand,

DATA: lwa_clskey TYPE seoclskey,

lt_clskey TYPE STANDARD TABLE OF seoclskey INITIAL SIZE 0,

lt_attributes TYPE STANDARD TABLE OF vseoattrib INITIAL SIZE 0,

lt_methods TYPE STANDARD TABLE OF vseomethod INITIAL SIZE 0,

lt_events TYPE STANDARD TABLE OF vseoevent INITIAL SIZE 0,

lt_params TYPE STANDARD TABLE OF vseoparam INITIAL SIZE 0,

lt_exceptions TYPE STANDARD TABLE OF vseoexcep INITIAL SIZE 0.

lwa_clskey-clsname = 'CL_GUI_ALV_GRID'.

APPEND lwa_clskey TO lt_clskey.

CALL FUNCTION 'SEO_COMPONENTS_SELECT'

• EXPORTING

• LANGU = SY-LANGU

• WITH_ATTRIBUTES = 'X'

• WITH_METHODS = 'X'

• WITH_EVENTS = 'X'

• WITH_PARAMETERS = 'X'

• WITH_EXCEPTIONS = 'X'

TABLES

clif_keys = lt_clskey[]

comp_attributes = lt_attributes[]

comp_methods = lt_methods[]

comp_events = lt_events[]

subcomp_parameters = lt_params[]

subcomp_exceptions = lt_exceptions[]

EXCEPTIONS

parameter_error = 1

OTHERS = 2.

IF sy-subrc <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

Hope this helps..
