If the pro-forma invoice has a contact person (CP) partner function, we wish to email output ZD00 to that contact person. We do not want the output to trigger, for example, if the billing doc does not have a contact person as it would end up in error anyway. What is the best way to handle this scenario - would it be through a requirement routine linked with the output in the output determination procedure to check whether the partner function first exists or not?
Also, since it is a pro-forma invoice, users may create the document multiple times. We only want the output to get triggered at the time of the first pro-forma invoice creation. How can this be accomplished?
Thanks!!
