Auto generate invoice (F2) when saving TA document

Hello,

I need to create a F2 invoice (as if I were using transaction VF01) when I create a TA document for selling a service (I'm using TAN positions). I'd like to generate this invoice as soon as I save the TA sales document without having to do anything else.

Does anyone know if this is possible and how could I do it?

Thank you very much in advance.

Regards,

David.
