f4 from standard domain in ALV

Hi friends,

In ALV output i have a column, which needs to be editable and F4 should come from Domain.

Domain is - XUBNAME, which is list of users from USR02 table.

while building fieldcatalog i made

LS_FIELDCAT-EDIT = 'X'.

LS_FIELDCAT-DOMNAME = 'XUBNAME'.

but still i am not able to get F4 functinality but column is editable.

Whats wrong?

Do i have to set any other parameter?

appreciate your help.

Regards,

Simha
