Thank you for your suggestions.
I have one more question -
I have invoices denominated in 2 currencies - USD (base currency) and EUR. How can I print only all EUR denominated invoices in a particular month?
I used the 'Print Invoices' function under the 'Customer' class of 'Customer and Sales Report'
I tried using the Currency Filter but the results will give me both USD and EUR invoices.
The reason I need to print only EUR invoices is because I want to add a comment line only on EUR invoices. Appreciate your help. Thank you.
