Output: Send a fax to a predefined fax number, not coming from customer ma

Hi colleagues,

I have the following requirement.

In the delivery a special output should be sent to a FIX FAX numer of a special vendor. This means not to the fax number from the current customer.

Is this possible somehow?

Everything is set up: Output type, determination, printing program and the fax is working already.

But how can I set up the condition record to use a special fax number?

One idea was to use a special partner function with the a partner inside that has the special fax number. Due to different reasons this is not possible...

Any idea?

Thanks in advance

Jens
