Oracle Expense report invoice

Hello,

We have an expense report for 17$ (2$ and 15$ expenses) that was approved and imported into AP invoice.These transactions are card transactions.

The invoice is created with 3 lines (2$ , 15$ and -17$) and the amount is 0$. I am not able to figure out why the invoice line for -17$ got created making the invoice amount 0$

The negative 17$ line is created with type Misc and description says 'credit card transaction reversal' although the user did not have such line in their expense report submitted.

Any suggestions are appreciated !

Thanks SV
