Is SuiteGL the best way to get Credit Memos for RMAs to hit a different account than Accounts receivable? or am I overlooking a config somewhere?

jhaubner: SuiteGL has 2 aspects. 1) you customise the GL impact on the current transaction (I.e. add on additional GL impact). 2) you create custom transactions and define it's GL impacts. Assuming you mean the 1st one, the transaction will hit Accounts receivable, SuiteGL will add another line to back it out of AR and hit the account which you define. You can also create JE's to do the same thing. Whether you automate that part through scripting or do manual is up to you. You will still be required to go into the customer record and click an accept payment to close off those lines.
