Setting Billing rates generates error: PDOException: SQLSTATE[HY000]: General error: 1 no such table: support_rate

Attempting to 'Set Billing Rates' under 'Support Ticketing System' consistently yields the following error:
PDOException: SQLSTATE[HY000]: General error: 1 no such table: support_rate:
SELECT COUNT(*) AS expression FROM (SELECT 1 AS expression FROM {support_rate} sr) subquery;
Array ( ) in PagerDefault->execute() (line 74 of /surtsey/userdata/www/druplex/drupal-7.9/includes/pager.inc).

Access to this system can be provided if required for debugging.
Is this a problem of needing to document the table creation is required before first use? or an installation issue where this isn't created?
