Runtime Error when Usercommand event is fired in ALV

[Former Member]

Hi all,

i'm writing ALv report and i successfully got Top of Page and End of List but when im try to fire Usercommand a run time error .

ERROR:

Too many parameters specified with PERFORM.

Error analysis

A PERFORM was used to call the routine "GENERATE_USER_COMMAND

"ZSAP1_ALV ".

This routine contains exactly 0 formal parameters, but the cu

call contains 2 actual parameters.

parameters.

CALL FUNCTION 'REUSE_ALV_EVENTS_GET'

• EXPORTING

• I_LIST_TYPE = 0

IMPORTING

ET_EVENTS = IT_EVENTS

• EXCEPTIONS

• LIST_TYPE_WRONG = 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.

WA_EVENTS-NAME = 'TOP_OF_PAGE'.

WA_EVENTS-FORM = 'TOP_FORM'.

APPEND WA_EVENTS TO IT_EVENTS.

CLEAR WA_EVENTS.

WA_EVENTS-NAME = 'END_OF_LIST'.

WA_EVENTS-FORM = 'END_OF_FORM'.

APPEND WA_EVENTS TO IT_EVENTS.

CLEAR WA_EVENTS.

WA_EVENTS-NAME = 'USER_COMMAND'.

WA_EVENTS-FORM = 'GENERATE_USER_COMMAND'.

APPEND WA_EVENTS TO IT_EVENTS.

*ENDIF.

and after this i created a form for Generate_user_command.

using perform keyword.

Please help me...

Thanks in Advance

The Error you are getting due to the Subroutine intterface parameters.

Use the Dynamic Subroutine for User_Command.

FORM user_command USING r_ucomm LIKE sy-ucomm
                                    rs_selfield TYPE slis_selfield.
CODE.       
ENDFORM.
