Regarding PRODH (product hierarchy)

Hi Experts,

i have created Z table with SICC code (last 5 digits of PRODH ). But our customer wants F4 help to be provided for that particular field.when look they into table through SE11 or SE16.So how do u do tht ..as i am not finding a table with only SICC code so tht i can go add with check table.

Regards,
