Multiple email remittances from Payables module in Oracle 11i

Using Oracle 11i we are moving forward with ACH payments to our suppliers in Payables.

The single remittance works fine, but I would like to know how to send multiple email remittances to our suppliers.

We use Exchange server - Outlook for email.

I have tried the following:

• Enter multiple email addresses separated by a comma + space
• Enter multiple email addresses separated by a comma (no space)
• Enter multiple email addresses separated by a semicolon

None of these methods work. So is it just not possible without custom IT support?

Thanks for your input and assistance.
