How to separate create accounting line amount in multiple account using SLA

Hi,

We currently use asset tracking to track our Fixed Asset Item and when we do a create accounting - CM on a reception, the debit expense account that is being used is an offset account which include the PO line amount + PO US taxes.

However, I want to know if there is a possible way through SLA to split that offset account amount in two different account with the right amount. Which mean that instead of having 1 total line amount for the offset account, I would like to have :

Offset account = PO Line Amount

Offset Tax Account = PO Line US TAXES
