+
+FS::cust_bill_pkg_discount - Object methods for cust_bill_pkg_discount records
+
+=head1 SYNOPSIS
+
+  use FS::cust_bill_pkg_discount;
+
+  $record = new FS::cust_bill_pkg_discount \%hash;
+  $record = new FS::cust_bill_pkg_discount { 'column' => 'value' };

+
+=head1 DESCRIPTION
+
+An FS::cust_bill_pkg_discount object represents the slice of a customer
+applied to a line item.  FS::cust_bill_pkg_discount inherits from
+FS::Record.  The following fields are currently supported:
+
+=over 4
+
+=item billpkgdiscountnum
+
+primary key
+
+=item billpkgnum
+
+Line item (see L<FS::cust_bill_pkg>)
+
+=item pkgdiscountnum
+
+Customer discount (see L<FS::cust_pkg_discount>)
+
+=item amount
+
+Amount discounted from the line itme.
+
+=item months
+
+Number of months of discount this represents.
+
+=back
+
+=head1 METHODS
+
+=over 4
+
+=item new HASHREF
+
+Creates a new record.  To add the record to the database, see L<"insert">.
+
+Note that this stores the hash reference, not a distinct copy of the hash it
+points to.  You can ask the object for a copy with the I<hash> method.
+
+=cut
+
+# the new method can be inherited from FS::Record, if a table method is defined
+
+sub table { 'cust_bill_pkg_discount'; }
+
+=item insert
+
+Adds this record to the database.  If there is an error, returns the error,
+otherwise returns false.
+
+=cut
+
+# the insert method can be inherited from FS::Record
+
+=item delete
+
+Delete this record from the database.
+
+=cut
+
+# the delete method can be inherited from FS::Record
+
+=item replace OLD_RECORD
+
+Replaces the OLD_RECORD with this one in the database.  If there is an error,
+returns the error, otherwise returns false.
+
+=cut
+
+# the replace method can be inherited from FS::Record
+
+=item check
+
+Checks all fields to make sure this is a valid record.  If there is
+an error, returns the error, otherwise returns false.  Called by the insert
+and replace methods.
