Salaried employee with no base pay - commissions only

Hello All,

We have an employee that only receives commissions, no base pay.  We setup a separate pay type for him with the following: Print Method = S (separate payment is required), Pay source = F, Auto Pay Method = C (override all auto pay instructions)

Commission is entered thru Speed Time Entry,.  When PrePayroll is processed, we receive an error regarding auto pay time card however there is no payment visible in Payment Review.  The register (R073012) does show a separate 'item' with hours but of course no dollars.  We have not posted thru to Final yet to see if a blank record is written to history.
