petty cash

Can any one tell me that does it necessary to record petty cash entries through vendor Accounts. or We can directly go through from cash Account. In this case can we have a control command to avoid duplication of invoices. we are using NAV 2009

I normally setup petty cash as a bank account, depending on how much it is used. You can then pay invoices from that bank, or make payments directly to a g/l account for other entries.
