=head1 NAME
FS::part_fee_usage - Object methods for part_fee_usage records
=head1 SYNOPSIS
use FS::part_fee_usage;
$record = new FS::part_fee_usage \%hash;
$record = new FS::part_fee_usage { 'column' => 'value' };
$error = $record->insert;
$error = $new_record->replace($old_record);
$error = $record->delete;
$error = $record->check;
=head1 DESCRIPTION
An FS::part_fee_usage object is the part of a processing fee definition
(L<FS::part_fee>) that applies to a specific telephone usage class
(L<FS::usage_class>). FS::part_fee_usage inherits from
FS::Record. The following fields are currently supported:
=over 4
=item feepartusagenum - primary key
=item feepart - foreign key to L<FS::part_pkg>
=item classnum - foreign key to L<FS::usage_class>
=item amount - fixed amount to charge per usage record
=item percent - percentage of rated price to charge per usage record
