Sending dunning letters by email

Hello frens

Can anyone tell me the procedure to send dunning letters as email? I want to send email when F150 TCode is executed. I am new to dunning and I dont know how to go about it.

I read on sdn about some BTEs and coding in teh function module but I cant understand it clearly.

Could anyone please help me out with this?

Thanks.

Regards,
