Payee Field not substituted in the accounting document from MIRO

Hi SAP Gurus,

I am in the process of automating the selection of Payee from MIRO and into accounting. I am using substitution rule, user exit and few other BAPI's but it didn't work out for me.

Is there any way which I could employ to select the payee automatically while posting from MIRO?

Kindly provide your valuable comments.

Thanks in Advance.
