Hi,

Event form names are appended to an internal table and passed to the ALV. And whatever you write inside that form

can be called through the function module.

What you are trying to do is modify the internal table with the form name, which does not exsist. Instead of this append it.

There are lot of example of this ALV list events.

DATA: T_EVENT TYPE SLIS_T_EVENT,

W_EVENT TYPE SLIS_ALV_EVENT.

CLEAR W_EVENT.

W_EVENT-FORM = SLIS_EV_AFTER_LINE_OUTPUT.

W_EVENT-NAME = SLIS_EV_AFTER_LINE_OUTPUT."AFTER_LINE_OUTPUT event

APPEND W_EVENT TO T_EVENT.

Thanks & Regards,
