29 An FS::cust_pkg_discount object represents the application of a discount to a
30 customer package. FS::cust_pkg_discount inherits from FS::Record. The
31 following fields are currently supported:
41 Customer package (see L<FS::cust_pkg>)
45 Discount (see L<FS::discount>)
57 order taker, see L<FS::access_user>
68 Creates a new discount application. To add the record to the database, see
71 Note that this stores the hash reference, not a distinct copy of the hash it
72 points to. You can ask the object for a copy with the I<hash> method.
76 # the new method can be inherited from FS::Record, if a table method is defined
78 sub table { 'cust_pkg_discount'; }
82 Adds this record to the database. If there is an error, returns the error,
83 otherwise returns false.
