Hi,
Could you please explain the process of petty cash process in detail how it works, may be an video on this will definetly works.

Thanks in Advance

Petty cash is not a very diserable way of paying for expenses but in some countries this process is more widely used than the others.
There is no built functionality in Oracle to handle Petty Cash process. However there are numerous ways in which petty cash could be handled in Oracle.

Here is one method:

Create Petty Cash Supplier and create Petty Cash - Prepayment Account

Enter prepayment invoice for Petty Cash Supplier

Debit: Petty Cash - Prepayment Account
Credit: AP Liability

Pay prepayment invoice

Debit: AP Liability
Credit: Bank Account

Now the person responsibility for handling petty cash has the check in his hand and he would cash it and will use the cash for minor expenses.

Enter the invoice in the system that you wish to pay by petty cash.

Debit: Expense
Credit: AP Liability

Apply the prepayment to the expense invoice

Debit: AP Liability
Credit: Petty Cash - Prepayment Account
