AR Receipt in alternative currency

Dear,

We need to make AR Receipt entries in alternative currency.

Our base currency is GBP and hence we invoice in GBP currency.

The company is also currency set up in GBP .

Few local customers are making payments in (AED) against invoices in GBP currency.

Is this possible?

I've ran a test by entering a standard receipt in AED but wouldn't allow me to select the GBP invoice. (Row->Select)

Can you please advise?

　

Thanks in advance.

REgards.

C.
