Condition table - pricing

Hi,

I am learning SD.

I am creating new condition table 888 - Sales Organisation / Customer group / Material for condition type customer discount K007.

I have copied from table no - 4.

While saving the new table 888, i confronted to a screen " Create Object Directory Entry", under the attributes there is a field PACKAGE.

What it indicates and what data I have to fill.

Please explain at the earliest.

Regards,

Ashish
