In nace I have created an output type ZRD0 and assigned communication strategy CS01. I assigned medium 5. I created a condition record for a customer for ZRD0. When I create a billing document it defaults in output type RD00. I can not run VF31 to get a first processing for this billing document. If I go to the billing document and insert ZRD0 then run VF31 I get my billing document email. But I want them to automatically get created for customers that want email. I do not want all to go to email so RD00 should still stay in effect. How do I set this up?
