Validation of User Conversion Rate on AP Invoice

Hi Team,

We are having below issue in our Invoice Processing.

1. When user Process the AP Invoice (Different Entered currency compared to Ledger Currency) user provides the Conversion Rate with "User Conversion Type"

2. But when they process the invoice, The Team enter the Conversion rate Mistakenly entered as 850786 instead of 0.850786. Which has created issues in FA and GL

We had Cancelled the invoice and Processed the Adjustment entries in FA and GL.

We wanted to understand is there any option to put a Message when these kind of conversion rate has been used on the invoice. Or We have any system control to validate the Conversion rate entered on the Invoice to avoid these kind of user mistakes.
