Sales return account

Hi,

I would like to have the double entry as below when performing AR Credit Memo:

Dr Sales return

Cr Customer

Meaning to say, the flow is SQ --> SO --> DO --> Invoice --> Credit Note. How can I post to Sales return account. I have tried setting 'Sales Credit Account' in GL account determination to be Sales Return account but it still post to Sales account instead of Sales Return account. Anyone can help?

I am using version 9.0 PL13.

thanks in advance.
