w_event TYPE slis_alv_event,

t_comment TYPE slis_t_listheader,

w_comment TYPE slis_listheader.

DATA: prgm like sy-repid.

PARAMETERS: custno TYPE kna1-kunnr.

SELECT vbeln

erdat

w_fcat-seltext_m = 'Document no.'.

APPEND w_fcat TO t_fcat.

w_fcat-col_pos = 2.

w_fcat-fieldname = 'erdat'.

w_fcat-seltext_m = 'Doc created date'.

APPEND w_fcat TO t_fcat.

w_fcat-col_pos = 3.

Specify the name of the subroutine (and also the fields in the field catalog) in upper case:

w_event-form = 'SUB'.

BR,

Hi,

unfortunately, the subroutibe SUB has no good name and it is your secret at what time (event) you want it called. If you need it for the top-of-page

I_CALLBACK_TOP_OF_PAGE parameter can be used.

P.S. There are so many sample programs B*ALV*

Hi,

I tried executing your code, it showed up dump. Then I realised that

1.Field names should be in capital case. Ex : w_fcat-fieldname = 'VBELN'.

2.Even name should also in capital case Ex : w_event-form = 'SUB'.

Please make these changes and you can see the ALV output with top_of page coming from your form SUB.

Hint: Please do a initial search in the forum before initiating a thread.

Hope this is helpful.

Regards

Pallavi
