- Click on New.
- Add the required parameters, under the Parameter Settings section.
- Under Output Channel Settings, click on Add Row button.
- In the Output Channel column, select E-mail.
- Repeat the steps 6 and 7.
- Click on Save and Close button.
The below error is displayed.
Duplicate Email/Fax/External System Channels are not allowed.
Cause
Some output combinations are not supported in the Output Channel Rules.
Resolution
- It is possible to maintain any number of channels in case of multichannel.
- It is not possible to maintain any channel twice except Printer.
- It is not possible to maintain two channels as Printer with the same Print Queue, they need to have different Print Queues.
- It is not possible to maintain two channels as Printer with Print Queue as ‘Default’ and blank as eventually the blank print queue will be set as ‘Default’ queue only.
Below are some examples of combinations and the results:
- E-mail, Printer(some queue), Fax, XMS – valid combination.
- E-mail, Printer, e-mail – invalid combination – it is not possible to have duplicate channels except Printer.
- E-mail, Printer(queue1), Printer(queue2), Fax – valid combination as duplicate printer channels are allowed with different print queue.
- E-mail, Printer(queue1), Printer(queue1) – invalid combination as duplicate printer channels are only allowed if they have different print queue.
- E-mail, Printer(‘DEFAULT’ queue), Printer(leave queue field as blank) – invalid combination as queue left as blank would be set as ‘DEFAULT’ print queue which will violate the point number 3.
