Unable to generate an Invoice against the Sales Order

Hi Team,

Here I am am getting an error under the interface table to stop generating an invoice in AR

Conversion rate for the given date, currency code, ledger and conversion type has not been defined

I have done all the necessary things to avoid this error however I am still getting it. I created a SO with price list in EURO and booked the order also lines are also closed.Defined the conversion rates and conversion type under the 'Finance' tab of the Order type. Currency is in GBP.

Please find the attached document for your reference and guide me if I am missing out anything here.
